tailieunhanh - Estimation of degree and direction of relationship of the yield contributing characters with yield in bread wheat under terminal heat stress

A study was conducted at Wheat Breeding section, RPCAU, Pusa, Samastipur, Bihar during rabi 2016-17 to evaluate the genotypes of bread wheat (Triticum aestivum L.) for terminal heat tolerance. Observations were recorded on plant height, number of tillers per plant, flag leaf area, days to fifty per cent flowering, canopy temperature, relative water content, spike length, number of grains per spike, spike fertility, chlorophyll content, days to maturity, thousand grain weight, harvest index, yield per plant, thousand grain weight susceptibility index and heat susceptibility index. 24 genotypes were grown under two environments . timely sown (non-stressed) and late sown (stressed). The experiment in each environment was laid out in Randomized Block Design with three replications. In order to find out the degree and direction of relationship of the yield contributing characters with yield and inter relationship between them, correlation (phenotypic and genotypic) coefficient analysis was carried out for all traits under investigation. | Estimation of degree and direction of relationship of the yield contributing characters with yield in bread wheat under terminal heat stress
