Abstract
of December and heat stress was induced due to the delay in sowing. For each genotype, yield attributing characters and physiological growth stages showed up differently, and the yield obtained was not similar. Among the parameters measured, genotypes with shorter vegetative periods and longer reproductive periods thrived well in existing environmental conditions. Days to anthesis and days to maturity were major parameters for selection criterion of yield effective genotype i.e., faster the anthesis, higher the yield; slower the maturity, higher the yield. Growth stages and quantitative yield attributing parameters justified the majority of variation in yield (80.2%) whereas the remaining is expected to be environmental and nutritional factors. Vijay variety (4.06 ton/ha) out-yielded the other six genotypes while NL1193 produced the least (1.97 tons/ha). Considering Vijay best, Vijay (4.06 ton/ha) and Gautam (3.52 ton/ha) are major genotypes recommended for the cultivation in a farmer's field with the least effect of heat stress in the Terai region of Nepal.
