HETEROSIS IN RICE HYBRIDS)
Main Article Content
Abstract
All the five testers used in this study acted as complete restorer for WA source and maintainer for O. perennis. The hybrids IR 58025 A x IR 54742 and IR 58025 A x IR 29723 showed greater heterotic expression for all the economic traits studied. The mean outcrossing percentage was high in V 20 A and IR 58025 A among the cytosteriles. High outcrossing rate was observed in IR 58025 Awhen interplanted with IR 29723. The crosses IR 58025 A x IR 29723 and V 20 A x IR 24 can be used in hybrid rice programme since it displayed higher heterosis with high outcrossing rate.
