POSSIBLE UTILISATION OF COMMERCIAL HETEROSIS IN INDIAN MUSTARD BRASSICA /UNCEA (L.) COSS & CZERN.

Published on

Possibilities of exploitation of heterosis using functional-genetic male sterility in B
juncea was explored by studying the extent of heterosis for yield and other characters
in 19 Fl hybrids against five commercial cultivars. Eighteen hybrids outyielded the
best check RLM 514. Three of them viz. MS X Pant Rai 1002, MS X RH 848 and
MS X RLC 1047 were significantly superior over the best check in seed yield by
81.19%, 5065% and 64.94 % respectively. The overall heterosis (taking all hybrids
and checks into account) for seed yield was very high (59.69%). The agronomic
superiority of the three hybrids was reflected by 1.5 to 2.0 times oil yield and one
week earliness in flowering as compared to RLM 514.
