| Abstract: | Using the mustard male sterile lines JL154-5A as sterility source, and fine cultivars of Brassica juncea (inbred lines) as male parents, four B. juncea CMS, DJA, K6A, HK -1A and K46A, with representativeness, stable sterile characteristic and fine economic characteristic, were obtained through cross hybridizing and continuous back cross. This paper systematically observed and identified the main characteristics, agronomic trait expression and SSR molecular marker of the male sterile lines, and confirmed that a lot of good B. juncea CMS could be utilized in future actual production. |
