Abstract:
The present study was based on the germplasm evaluation experiment involving evaluation of 72 germplasm including three checks viz., Shusk Samrat, NDR-359 and MTU-7029. The field experiment under present investigation was conducted in Kharif season 2019 at the Crop Research Station (CRS) Masodha and lab experiments was conducted in Seed Testing Laboratory, Seed Technology Section, ANDUA&T, Kumarganj, Ayodhya (UP). The experiment was conducted in Augmented Block Design with three replications. The data were recorded for 17 quantitative characters to study genetic variability, heritability and Genetic advance. Analysis of variance revealed that there is considerable variability among the genotypes. On the basis of mean performance, high seed yield per plant were exhibited by the genotypes LSD-1, MTU-7029 and NDR 359. Analysis of variance among 72 genotypes showed significant difference for all characters studied. The high estimates (>15%) of phenotypic (PCV) and genotypic (GCV) coefficients of variation were recorded in case of panicle bearing tillers per plant followed by biological yield per plant, seed yield per plant and plant height indicating that these characters could be used as selection for crop improvement. The higher estimates of heritability coupled with moderate genetic advance for plant height, days of 50% flowering, biological yield per plant, days to maturity, seedling dry weight, vigour index-II, seed yield per plant, panicle length, 1000-grain weight, seedling length, vigour index-I, grains per panicle and speed of germination, indicated that heritability of the trait is mainly due to additive effect and selection is effective for such traits.
