Abstract:
Indian mustard is a most widely cultivated oilseed crop of India. The productivity of this crop should be boost up in order to meet out the future edible oils demand of the country. Heterosis breeding could be a potential alternative for increasing productivity of Indian mustard. Therefore, 40 crosses had developed in Line x Tester fashion in order to study the extent of heterosis for yield and its component traits in Indian mustard. In terms of heterotic effects for both seed yield and oil content, four best hybrids were RH 1599-44 × DRMR 2035, RH 1599-44 × EC 597328, PM 26 × DRMR 2035 and RH 1658 × EC 597328. Besides, heterosis for seed and oil yield, later two crosses also expressed significant heterotic effects for most of the yield attributing and agronomically desirable traits. These cross-combinations can have potential to serve as commercial F₁ hybrids after transferring them in to suitable cytoplasmic genetic male sterility system.
