Abstract

Heterosis was estimated in Indian mustard for 12 quantitative characters. The experimental material consisted sixty F 1′s derived in a line x tester mating fashion (4 lines + 15 testers) and one standard variety ‘Kranti’ as control. The five crosses RLM 198A x YRT-3 (104.40%) followed by PCMS 106A x Jatai ral (98.12%), RLM 198A x Jatai ral (81.13%), Pusa Bold A ‘siifolia’ x JMM 1628 (73.28%) and PCMS 106A x RK 8401 (63.19%) showing heterobeltiosis for seed yield with significant and positive sea effects; Desirable heterobeltiosis for oil content was exhibited by three crosses RLM 198A x RH 8819 (6.91%), followed by Pusa Bold A ‘siifolia’ x JMM 1628 (4.49%) and RLM 198A x BIOYSR (3.21%) and two crosses Pusa Bold A ‘siifolia’ x JMM 1628 (3.76%) and Pusa Bold A ‘siifolia’ x Local mustard (3.66%) were expressed significant and positive standard heterosis and sea effects.
