Abstract

Assessment of genetic variability and heritability for grain yield and its associated traits in F2 populations of bread wheat (Triticum aestivum L.)

Highlights

T, tillers plant-1, spike length, spikelets spike-1, grains spike-1, grain weight of main spike (g), grain yield plant-1 (g), seed index (g), biological yield plant-1 (g) and harvest index (%)
Genetic variability is the basic utensil of breeding tactics which could be achieved through hybridization of diversified genetic material
The data were recorded for the ten characters i.e. plant height, tillers plant-1, spike length, spikelet spike-1, grains spike-1, grain weight of main spike (g), grain yield plant-1 (g), seed index

Summary

Introduction

T (cm), tillers plant-1, spike length (cm), spikelets spike-1, grains spike-1, grain weight of main spike (g), grain yield plant-1 (g), seed index (g), biological yield plant-1 (g) and harvest index (%). The result regarding analysis of variance, all the genotypes, parents and hybrids displayed highly significant and significant differences for the all the attributes at 0.01% and 0.05% probability level. It is concluded that these hybrids may be the best choices for the exploitation of heritability and hybrid crop development in bread wheat or selection of desirable plants from later segregating generation. The data were recorded for the ten characters i.e. plant height (cm), tillers plant-1, spike length (cm), spikelet spike-1, grains spike-1, grain weight of main spike (g), grain yield plant-1 (g), seed index (1000 grain weight, g), biological yield plant-1 (g) and harvest index (%). The parents were highly significant at 0.01% probability level for plant height (cm), spikelets spike-1, grains spike-1, seed index (1000 grain weight, g), biological yield plant-1 (g) and harvest index (%), whereas significant at
