One of the most pressing concerns related to seed supply mechanisms of improved varieties of rainfed crops is how to establish sustainable seed provision systems for commodities that cannot be economically supplied through a centralized, formal seed industry. The seed supply bottleneck primarily affects self-pollinating crop seeds saved and sown year after year in local systems. The restrictions imposed by national seed authorities on free exchange and marketing of seed, especially compulsory variety registration and seed certification, as practiced by many developed and developing countries are constraints on the efficient functioning of the formal seed sector and on the development of alternative seed systems. A good quality and improved variety seed can enhance production by 20% and with improved crop production practices can increase yield by 30–40%. Availability and accessibility to improved variety seed is a big task. Sorghum seed system is very unique in India with contrasting situations and systems. In the case of post-rainy season sorghum cultivated on black soils under residual moisture condition, open-pollinated varieties are the cultivar choice because of stringent quality considerations and lack of appropriate hybrids and inadequate hybrid seed production and supply chain. Ways of strengthening seed systems that could potentially address the needs and counter the vulnerabilities of smallholder farmers in these areas using specific seed delivery models need to be explored. Research and development programs of State Agricultural Universities (SAU) have developed improved varieties and are available in public domain for several years. To augment seed production and for dissemination of improved varieties, “seed consortium” model was developed with various partner institutions like the Department of Agriculture, agriculture universities, seed certification agency, state and national seed development corporations, private seed companies, NGOs, SHGs, and KVKs was brought onto one platform with a basic objective to enhance availability and accessibility of improved variety seed at right time and for right price to increase production and productivity of post-rainy sorghum. The present chapter discusses the successful implementation of seed consortium model to suggest the way forward for developing sustainable seed systems for higher productivity in sorghum.

Interaction of plants with environmental factors and microbial world is a dynamic process. As part of this ever-changing process new disease emerges or minor disease may become major with time. This chapter presents a very brief account of well-studied old diseases of sorghum and emphasizes on emerging diseases with particular reference to India. Description of sorghum diseases caused by fungi, bacteria, and their transmission through seed implies quarantine significance. Thus, awareness about the quarantine pests of different countries is essential for facilitation of smooth germplasm exchange. Diseases distribution, losses, symptomatology, and management options have been discussed in detail. In this chapter, we have generated environmental (ecological) niche model for the pathogens causing sorghum diseases due to fluctuations in environment caused by climate change. Ecological Niche Model using Maxent is a class of method that uses occurrence data in conjunction with environmental parameters to make a correlative model of the environmental conditions that meet pathogens’ ecological requirements and predicts the relative suitability of habitat.

- Abstract
Sorghum is the most important cereal crop grown in the semi-arid tropics (SAT) of Africa, Asia, Australia and Americas for food, feed, fodder and fuel. It is the fifth most important cereal crop globally after rice, wheat, maize and barley, and plays a major role in global food security. Sorghum is consumed in different forms for various end-uses. Its grain is mostly used directly for food purposes. After the release of the proceedings of two international symposia in the form of books “Sorghum in Seventies” and “Sorghum in Eighties”, global sorghum research and development have not been documented at one place. Of course, few books on sorghum have been released that focus on specific issues/research areas, but comprehensive review of all aspects of recent development in different areas of sorghum science has not been compiled in the form a single book. This book is intended to fill in a void to bridge the gap by documenting all aspects of recent research and development in sorghum encompassing all the progress made, milestones achieved across globe in genetic diversity assessment, crop improvement and production, strategies for high yield, biotic and abiotic stress resistance, grain and stover quality aspects, storage, nutrition, health and industrial applications, biotechnological applications to increase production, including regional and global policy perspectives and developmental needs. This book will be an institutional effort to compile all the latest information generated in research and development in sorghum across the globe at one place.

To meet the energy requirement for transport, blending automotive fuels with ethanol has been mandated in India like several other countries across the globe. The entire blending requirement has to come from molasses (by-product of sugarcane). Ethanol produced from molasses will not be able to meet the blending targets due to cyclical nature of sugar cane production resulting in shortage of molasses and its competing uses (potable and pharmaceutical use). This has promoted research efforts to augment energy sources that are sustainable and economically viable. One such source that can be commercially exploited for ethanol production is sweet sorghum. The sugars in the stalks of sweet sorghum can be crushed to produce juice, which can be processed into ethanol for blending. An attempt is made in this paper to assess viability of ethanol production from sweet sorghum. Net Present Value (NPV), the indicator of economic viability assessment, is negative and would thus be difficult for the industry to take off under the current scenario of ethanol price, feedstock price and ethanol recovery rate. Hence, an enabling environment and policy support for bio-ethanol production from sweet sorghum is crucial to meet future blending requirements.

The paucity of information on the moulds in Indian pearl millet (Pennisetum glaucum) led to the studies that were conducted at ICRISAT, India to evaluate (a) 447 germplasm accessions of 32 countries for mould reaction in rainy season, (b) threshed grain mould rating (TGMS) and mycoflora on grains of each accession, and (c) mould scores in field and in vitro. Post physiological maturity evaluation showed that 16% of the accessions secured a mould rating of 2. In TGMS, 18% were mould free and 57% secured a rating of 2 on a 1 – 9 scale. Assessment of twenty representative accessions in vitro against individual and mixed conidial suspensions (1610(6) conidia ml(71)) of Fusarium moniliforme, F. pallidoroseum and Curvularia pennisetti indicated significant correlation (r¼0.97) between the overall field and in vitro scores of mixed spores inoculations. The mycoflora for TGMS in blotter test revealed that Fusarium moniliforme, F. pallidoroseum, Curvularia pennisetti, Helminthosporium spp., Alternaria spp. and Colletotrichum spp. to be the major fungi affecting pearl millet grain. It is advisable to harvest panicles at the physiological maturity stage to obtain better quality grains. A strong negative correlation between TGMS and % GS (r¼0.4601) and positive correlation between TGMS and % UGS (r¼0.4654) indicated that, the lesser the threshed grain mould rating higher the % seed germination.

The last one to two decades have seen several countries stipulating a mandatory requirement of 5–10% blending of biofuels with petrol and diesel. The mandatory blending has triggered a rapid growth in the biofuel sector. Several governments have put in place biofuel policies that have a bearing right from the production of biofuels crops at the farm to their conversion into transport-grade biofuels to be utilised for blending purpose. This paper highlights the salient features of India's biofuel policy and discusses how it influences the economic viability of ethanol production and its commercialisation in the country. The Government of India provides a wide range of policy incentives to promote biofuels as an alternative energy source. The policy challenges affecting biofuel development are discussed under the framework adapted from the Global Subsidies Initiative of Steenblik (2007) showing the existing policies and distortions along the biofuel supply chain to promote alternate feedstocks. For long-term sustainability of ethanol production for blending mandates, this paper explores the options to augment bioethanol production using alternative feedstocks like sweet sorghum that is grown in the drylands and policy support required for its promotion, which will benefit all the stakeholders of the bioethanol supply chain in the long run.

- Abstract
Sweet sorghum is one of the many types of cultivated sorghums and is a promising multipurpose biofuel feedstock. The objective of this study was to assess phenotypic and genotypic diversity among 75 selected diverse sweet sorghum genotypes available at ICRISAT-Patancheru. Genotyping-by-sequencing generated 135,162 SNPs having minor allele frequencies > 0.20. Cluster analysis grouped the genotypes into three distinct clusters, with some of the sweet sorghum lines falling in distinct clusters. This grouping pattern was in conformity with available race and pedigree information. Mean performance and analysis of variance for sugar yield-related traits shows considerable variability. The results also revealed close genetic relationships between elite genotypes such as ICSV 25316, ICSV 25311, SSV 74 and ICSV 25300 that are superior for various sugar yield-associated traits like plant height, biomass, juice yield and sugar content. Not surprisingly given their pedigrees, these elite materials grouped together tightly in a single sub-cluster. [ABSTRACT FROM AUTHOR]

- Abstract
Sweet sorghum is a multipurpose biofuel feedstock that offers grain for human consumption, fodder for livestock and ethanol for transportation purposes. The knowledge on sugar components at different phenological stages of crop growth and identification of appropriate stage of harvesting is critical for sweet sorghum commercialization and value chain sustenance. In this regard, sweet sorghum stalk yield, juice yield, Brix%, pH, sugars (sucrose, fructose and glucose) and their content were analyzed at three different phenological stages i.e. the dough stage, physiological maturity and post-physiological maturity. Variations in sugar content at different growth stages revealed that the sugar yield was high at physiological maturity, but highest at post-physiological maturity. Sucrose accounts for major fermentable sugar (about 70%) and it sharply increased by 146% from dough stage to post-physiological maturity. The variation in the monosaccharides content (glucose and fructose) is not statistically significant. This study points to the potential scope for widening the harvesting window of sweet sorghum, by cutting the stalks from physiological maturity stage and beyond up to 15 days (post-physiological maturity), thus helping the commercial distilleries by addressing a major impediment in sweet sorghum value chain. The entries SP 4495, SP 4511-3 and SPV 422 are suitable for harvesting in a wider window of time as the sugar levels are sustained at same level from physiological maturity to post-physiological maturity.

- Abstract
Written and edited by a team of industry experts, this exciting new volume covers the field of renewable lubricants, their processing, optimization, end-use application, and their future potential. Biolubricants are a viable alternative to synthetic lubricants because they are produced from organic materials such as plant oils, waste oils and by-products. Renewable biolubricants are the subject of research because of their biodegradability, eco-friendliness, and favorable socioeconomic consequences to counteract imitations of synthetic lubricants. Biolubricants have thus emerged as an ideal substitute for mineral oil-based lubricants, as significant economic and environmental acceptability has been received over the last few decades and it has been estimated that there would be a further steady growth in its demand over the next few decades. Furthermore, biolubricants'high-quality lubricating properties, high load carrying ability, long service life, and fast biodegradability have expanded the recent interest. These lubricants can be derived from different sources of vegetable oils, non-edible oils, waste cooking oils (WCO) and microbe-derived oils. Among all these sources, the use of WCOs and microbe-derived oils have received immense interest and provide superior quality biolubricants. This outstanding new volume covers the prospects and processing of feedstocks for biolubricants, extraction techniques, new advancements in the field of bio-based lubricants, epoxide lubricants, hydrogenated lubricants, microbial-based biolubricants, nano-biolubricants, polyester-based biolubricants, lubricants from waste oils and waste materials, its economic and environmental acceptability and biorefinery approaches. The book will be helpful to industry professionals and engineers of all types, students, and other stakeholders working in the field of lubricant, chemical engineering, mechanical engineering and material science, tribological sectors and biorefinery industries. It will also be of great interest to new start-up companies working in the area of processing feedstocks for biolubricant production and end use application, biorefineries, valorization of biolubricant waste, and in the recycling industries.
