Muscat Hamburg (Panneer) is the most popular cultivar in Tamil Nadu for its pleasant musk flavor. It is consumed as table variety and also used for juice and wine-making purposes. The present investigation was conducted during summer and winter pruning from April 2016 to March 2018, in the grapes vineyard located at Shanmuganathy dam road, Rayappanpatty village in Cumbum valley of Theni district, Tamil Nadu. The experiment was laid out by adopting Randomized Block Design with seven treatments and three replications. The exeprimental results revealed that the treatment with foliar application of chelated EDTA calcium @ 0.2% + boric acid @ 0.1% recorded the maximum number of bunches (41.00 vine-1), fruit yield (14.87 kg vine-1), individual bunch weight (636.87g), bunch volume (498.42 mL) and TSS (19.53ºbrix). The minimum berry cracking (3.46%), titrable acidity (0.52%) and physiological loss in weight (10.18%) were also recorded in the treatment with chelated EDTA calcium @ 0.2% + boric acid @ 0.1% (T5) as compared to other treatments. Further, the same treatment combination noted the lowest berry shattering (2.42%). Whereas the highest berry diameter was recorded in the treatment with a spray of calcium chloride @ 0.3% than all other treatments. [ABSTRACT FROM AUTHOR]

Association study and selection of best rice genotypes based on grain quality traits was experimented with 44 rice cultures. The study material comprised of 40 stabilised mutant lines of ADT 37 and ADT (R) 45 and four varieties. The grains with 11-13 per cent of moisture content were subjected for all grain quality estimation/quantification. It is observed that the amylose did not show any correlation with any of the milling properties as well the Alkali Spread Value. Protein has a negative correlation with Gel Consistency. Kernel breadth exhibited a negative correlation with most of the traits. Volume expansion has a good positive correlation with grain elongation after cooking. Upon comparison of selection indices viz., Multiplicative Index, Index Free of Weights and Parameters, Base Index, Classical index, Index based on the sum of Ranks and Index based on gains desired, the multiplicative index has given higher gains for most of the traits. However the index based on the sum of ranks was found to give good weightage to all the important traits. Hence the genotypes viz., ACM17006, ACM 18001, ACM18021, ACM18011, ACM18017 were found promising in this study based on the sum of ranks index. [ABSTRACT FROM AUTHOR]
