Genotypic evaluation of different rice varieties for yield and yield related traits of Eastern Uttar Pradesh

Abstract

Investigation were undertaken at Zonal Agricultural Research Sub Station, (ANDUAT) Ghazipur, during 2018 and 2019 to study the performance of various rice genotypes for yield and yield characters under the agro-ecological conditions of Gazipur to investigated among 10 rice varieties including check. The experiment was laid out in Randomized Complete Block Design (RCBD) with having three replications. This evaluation is vital to know the effects of various characters on yield for selection criteria for high yielding genotype. Yield and yield related traits were studied. Statistical analysis exhibited that rice varieties differed significantly for days to 50% flowering (DFF), plant height cm (PH), panicle length cm (PL), panicle per sqm, (EBT), days to maturity (DM), grain yield q/ha (GY),total grain/panicle. Sterility % and thousand grain weight (TGW). Moreover, significantly positive genotypic correlations of grain yield with PH, PL, EBT and TGW were observed. Principal component analysis also classified superior varieties, shows that maximum yield was recorded for NDR- 370135 (58.20 q/ha), followed by NDR-370133 (57.30q/ha), NDR – 370134 (56.68 q/ha) and NDR- 2105 (52.85 q/ha).These varieties can be used as commercial cultivars in Gazipur area after multi- location yield test trials.
