Abstract

The associations among phenotypic and genotypic traits of rice and the pattern influence on rice grain yield were investigated among 18 rice varieties. This evaluation is vital to know the effects of various characters on yield for selection criteria for high yielding genotype. Experiment was carried out in randomized complete block design (RCBD) with three replications. Yield and yield related traits were studied. Statistical analysis exhibited that rice varieties differed significantly for days to 50% heading (DH), number of primary (PB) and secondary branches per panicle (SPB), spikelets per panicle (SP), days to maturity (DM), thousand grain weight (TGW), and grain yield (GY). Moreover, significantly positive genotypic correlations of grain yield with PB, SPB, SP and TGW were observed. Principal component analysis also classified superior varieties. Swat-1, IR-8, DR-82 and Fakhr-e-Malakand showed superiority for yield and yield related traits. These four varieties can be used as commercial cultivars in Peshawar area after multi- location yield test trials.
