Genetic variability, correlation and path coefficient analysis for metric traits in wheat (Triticum aestivum L.)


Najibullah Hakimi, G Roopa Lavanya, G Suresh Babu, Ali Ahmad

Wheat genotypes (including one check) were evaluated during Rabi 2015-2016 to determine genetic parameters for grain yield and its component characters in order to select the more desirable traits which may contribute for the improvement of yield. The mean sum of squares due to genotypes was significant for all the fifteen characters studied. High magnitude of GCV and PCV were recorded for seed yield per plant, number of grains per spike and biological yield. High heritability (h2bs) was recorded for all characters under study except. High genetic advance was recorded for plant height, number of grains per spike, peduncle length and test weight. Seed yield exhibited positive significant correlation with biological yield, plant height, test weight, peduncle length, and number of grains per spike at both genotypic as well as phenotypic level. While seed yield exhibited positive significant correlation with harvest index, flag leaf length and number of spikelets per spike at genotypic level. Biological yield and harvest index recorded direct high effect on grain yield per plant both genotypic and phenotypic levels. These traits should be given due emphasis for future bread wheat genetic improvement which may yield high genetic advance under proper selection pressure in a breeding program.
