VARIETAL IMPROVEMENT OF WHEAT UNDER RAINFED CONDITIONS IN MID-WESTERN TERAI OF NEPAL

Subarna Sharma, Nav R. Acharya, Sharad Adhikari & Krishna K. Mishra

Coordinated Varietal Trials (CVT) of wheat were planted under rainfed conditions at Regional Agriculture Research Station Khajura in winter season of 2011/12 and 2012/13 and Initial Evaluation Trials (IET) were planted in 2012/13. Trials were planted in Randomized Complete Block Design and recommended cultivation practices were followed. In CVT, combined analysis of genotypes over the years revealed significant differences in terms of days to heading, maturity days, grains per spike, grain yield and straw yield. Significantly highest grain yield was obtained in genotype NL1094 followed by Bhrikuti. Correlation coefficient showed that days to maturity had highly positive correlation with days to heading. Similarly; in IET, tested thirty genotypes showed significant difference for grain yield and genotype NL1193 revealed the highest yield followed by BL 4406. Correlation coefficient computation showed that days to maturity had positively highest and highly significant correlation with plant height.
