| Abstract | Genetics of glucosinolate content was investigated using six generations (P1, P2, F1, F2, B1 and B2) of three crosses, viz., NUDHYJ-3×Varuna, NUDHYJ –3×RL 1359 and NUDHYJ-3×PCR 7. NUDHYJ-3 is a double low strain and Varuna, RL 1359 and PCR 7 are the important varieties of Indian mustard. High glucosinolate content was partially dominant over low glucosinolate content in all the three crosses as revealed by F1 means. The parents NUDHYJ-3, source of low glucosinolate and three high glucosinolate varieties differed by at least 4-5 pairs of major genes for glucosinolate content. Non-allelic interactions were predominant in the genetic control of this trait in all the three crosses as simple additive-dominance model was inadequate to explain total genetic variability for this trait in different generations of the crosses. Although both additive and dominant effects were significant but prevalence of dominant effects along with their interactions suggested that early generation selection for low glucosinolate would not be quite effective. The selection to be useful should be deferred to advanced generations when dominance effects are substantially reduced. The bi-parental mating followed by pedigree selection in F3 / F4 generation may a suitable approach to select for low glucosinolate content. |
