ABSTRACT

The association analysis and selection indices were worked out in 28 genotypes of wheat planted under three dates of sowing for representing major growing conditions of wheat. The correlation studies indicated that grain yield per plant had positive correlation with grain yield per spike and number of grains per spike; grain yield per spike with harvest index and number of grains per spike in all the three dates of sowings. Thousand grain weight was an important yield contributing trait in rainfed situation and it exhibited positive correlation with harvest index in all the sowing dates suggesting its importance in improving yieid per se. Selection indices revealed that the genotype 747, 305–222 and Sujata had the highest index value in first, second and third dates of sowing respectively.
