An investigation was carried out to estimate the nature and extent of genetic variability​ ​among twenty Amaranthus genotypes (Amaranthus spp.) under a randomized block designduring the year 2019-20. The phenotypic coefficient of variation was higher than the genotypic​ ​coefficient of variation for all the traits. High genotypic coefficient of variation (GCV) and​ ​phenotypic coefficient variation (PCV) was observed for leaf area, leaf area index, leaf area​ ​duration, AGR, dry weight of leaf per plant, specific leaf weight, speed of germination,​ ​chlorophyll content and ascorbic acid (vitamin C). Moderate GCV and PCV were observed​ ​for leaf length, leaf width, petiole length, dry weight of stem per plant, leaf: stem ratio and​ ​foliage yield per plant. The high estimates of heritability coupled with higher values of genetic​ ​advance as per cent mean (GAM) were observed for the parameters like test weight, speed of​ ​germination, germination percentage, seedling dry matter, seedling vigour index-1, seedling​ ​vigour index-2, plant height, leaf length, leaf width, leaf area, leaf area index, leaf area​ ​duration, AGR, specific leaf weight, stem weight per plot, dry weight of leaf, dry weight of​ ​stem, leaf: stem ratio, foliage yield per plant, chlorophyll, ascorbic acid and beta- carotene​ ​content which indicates the predominance of additive gene action. Arka Arunima,​ ​Chikmagalur local, IC-551486, IC-551494 and IC-551466 recorded high foliage yield per​ ​plot and these can be utilized in further breeding programmes.

Eighteen genotypes of cluster bean [Cyamopsis tetragonoloba (L.) Taub] were evaluated to estimate variability, broad sense heritability, genetic advance over mean and diversity for vegetable pod yield and related attributes, during summer 2014-15. Maximum range of variability was observed for number of vegetable pods per plant, number of clusters per plant and pod yield. High heritability coupled with high genetic gain in percentage was observed for number of pods per plant, number of clusters per plant, pod yield and days to first flowering. The maximum intra cluster distance was observed in cluster I and intercluster distance was high between cluster I and cluster III, this indicated wide range of variability among clusters. The per cent contribution towards genetic diversity was high for dry pod yield per plant (29.41%) followed by number of dry pods per plant (24.18%) and seed yield per plant (16.99 %).
