Abstract:

Studies on genetic variability parameters were carried out in Quality Protein Maize (QPM) genotypes at AICRP on maize Rajasthan College of Agriculture, MPUAT, Udaipur, Rajasthan and in kharif 2014 for 15 various traits like days to 50 per cent tasseling, days to 50 per cent silking, anthesis silking interval, days to 75 per cent brown husk, plant height, ear height, ear length, 100-grain weight, grain yield per plant, harvest index, oil content, starch content, protein content, tryptophan content and lysine content in QPM genotypes. The experimental material consisting of 18 lines and 4 standard checks viz., Pratap QPM hybrid-1, Vivek QPM-9, HQPM-1 and HQPM-5 was raised in randomized block design in three replications. In the present investigation significant differences between the test entries were observed for all the yield and yield contributing traits and quality parameters. The grain yield per plant had highly significant and positive correlations both at genotypic and phenotypic levels with 100-grain weight (rg=0.863, rp=0.829), starch content (rg=0.657, rp=0.649), harvest index (rg=0.529, rp=0.504), lysine Content (rg=0.518, rp=0.486), ear length (rg=0.476, rp=0.463), tryptophan content (rg=0.468, rp=0.457) and ear height (rg=0.351, rp=0.339). The highest positive and direct effect was found for days to 50% tasseling (5.559) followed by lysine content (0.710) and starch content (0.439). The negative and direct effect was found for days to 50% silking (-5.774) and plant height (-0.331).
