| Description |
The present investigation was carried out to study genetic variability for different biometrical and harvest plus traits and association among the different traits in pearl millet. The experimental material was comprised of 100 advance inbred lines grown in randomized block design in two replication during kharif 2012. The observations were recorded for 12 field traits [Days to 50 per cent flowering, plant height (cm), spike length (cm), spike girth (cm), total tillers (number/plant), effective tillers (number/plant), leaf length (cm), leaf width (cm), ear weight (g), grain yield (g/plant), dry fodder yield (g/plot), 1000-grain weight (g)] and harvest plus traits [ Iron and Zn content (mg / kg grains)]. Dry fodder yield, grain yield, ear weight, iron content and 1000-grain weight had high heritability and high genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) Correlation study revealed that grain yield per plant expressed positive significant correlation with dry fodder yield followed by ear weight, total tillers /plant, effective tillers/plant and plant height. The path coefficient analysis suggested the importance of dry fodder yield, ear weight, total tillers /plant, effective tillers /plant, leaf length and zinc content as these had positive direct and indirect effects on grain yield. Therefore, selection for higher yield will be useful if it is based on traits such as dry fodder yield, ear weight, total tillers/ plant and effective tillers/plant. Inbreds 12-0125 [1660 (M.T.)], 12-0069 (IPS 98-2) and 12-0107 (H 08/004) were found better not only for grain yield but also for traits viz., plant height, spike girth, total tillers per plant, effective tillers per plant , leaf width, ear weight, dry fodder yield and iron & zinc content |
