Genetic analysis and heterosis breeding of seed yield and yieldattributing traits in Indian mustard (Brassica juncea (L.) Czern & Coss.).

Among the 28 crosses evaluated, 7 F 1 hybrids demonstrated highly significant and desirable negative heterosis over the better parent for early flowering, namely RW-85-59 × DRMR-15-16 (− 6.550), RW-85-59 × SKJM-05 (− 7.830), RW-85-59 × Kranti (− 5.200), RW-85-59 × PHR-2 (− 9.040), DRMR-15-16 × Kranti (− 6.360), DRMR-15-16 × RNWR-09-3 (− 8.190), and DRMR-15-16 × PHR-2 (− 9.040).
