Abstract :
The present study was carried out to access the vigor of F1 hybrids for drought tolerance. Higher heritability and genetic advance were found for dry root weigh and total dry weight, strong genotypic correlation was found for dry root weight, dry shoot weight and total dry weight. Higher dry root and shoot weight and dry root-to shoot weight ratio was found for B-336 and Sh-139 × EV-347, B-336 × EV-347, EV-1097 × EV-340, EV-1097Q × B- 316 and B-327 × EV-340. Higher heterosis and heterobeltiosis were found for F1 hybrids for dry root weight EV-1097 × EV-340 (190.476, 154.167), EV-1097 × Pop/209 (112.121, 94.444), dry shoot weight EV-1097 × Pop/209 (130.769, 114.286), dry root-to-shoot weight ratio EV-1097 × B-316 (115.519, 52.985) and B-27 × EV- 340 (138.657, 102.344) and for total dry weight EV-1097 × Pop/209 (175.391, 108.333), EV-1097 × EV-340 (133.846, 85.366) respectively. The higher heterosis and heterobeltiosis for all traits indicated that hybrid vigor was higher due to which hybrids may be used for drought tolerance and to improve grain yield of maize.
