Inter-relationship studies among grain yield and its component characters in wheat (Triticum aestivum L.)

Author(s): Ibrhim Hassani, Shailesh Marker and GM Lal
Abstract:
An experiment was conducted during Rabi (2015-16) by using randomized block design with three replications and 20 wheat genotypes along with two checks to obtain information on genetic variability parameters, heritability, genotypic and phenotypic co-relations. Analysis of variance revealed that there were significant differences among genotypes. On the basis of Per se performance for grain yield per plant, genotype viz: SHIATS BW 1105, SHIATS BW 1103, SHIATS BW 1101 and SHIATS BW 1111 were found promising line as they showed high value for grain yield of wheat. Wide range of phenotypic (VP or σ2p) and genotypic variance (VG or σ2g) were observed in the experimental material for all the traits studied. High estimates of phenotypic coefficient of variation (PCV) was obtained for grain yield per plant (16.33) and the lower phenotypic coefficient of variation (PCV) was observed for days to maturity (2.39), whereas wide range of genotypic coefficient of variation (GCV) was observed for all the traits, however the high estimates from grain yield per plant (14.40) and the lower estimates was recorded for days to maturity (1.16). High heritability (broad sense), in same value were recorded for plant height (0.89), number of grains per spike (0.89), while Moderate heritability was observed for peduncle length spike length, harvest index, days to maturity and the low heritability were observed for days to maturity. Suggest predominance of additive gene action in the expression of these traits. Grain yield showed the positive significant genotypic and phenotypic association with days to flowering, flag leaf length, leaf width, days to maturity, number of tiller per plant, no of spikelets per spike, number of grains per spike, biological yield, and test weight.
