Yield and oil content of doubled haploids of mustard (Brassica juncea (L.) Czern. and Coss.)

Abstract

Progenies of androgenetic doubled haploid plants of mustard cv TM-4 in A4−A6 generations were evaluated for their seed yield and oil content. Eight progenies in the A5 generation out of the 97 (8%) A1 plants regenerated were equal in yield to the parent cultivar. The oil percentage in these doubled haploids were in the same range as that of the parent cultivar. The remaining androgenetic doubled haploids were statistically lower in yield. The data indicates that about 8% of thein vitro raised androgenetic plant progenies had no adverse effects on yield potential and point to the need for obtaining a large number of androgenetic doubled haploids to recover genotypes more productive than the better parent.
