Introgression of earliness in Brassica napus L. I. An interspecific B. juncea and B. napus cross


, : Introgression of earliness in Brassica napus L. I. An interspecific B. juncea and B. napus cross. International Journal of Tropical Agriculture 11(1): 14-19

B. juncea cultivars Varuna and Pusa Barani were crossed with B. napus cultivars ISN4 and ISN706 during 1987-88. Subsequent segregating and backcross generations grown during winter 1989-90 were studied for days to flowering, flowering period, seed development period and days to maturity. Transgressive segregants were obtained for flowering period, seed development period and days to maturity in the F2 and F2M2 generations.

A new strategy to localise and characterise interspecific introgressions in the genus Brassica is presented. It consists of the localisation of RAPD specific markers from the donor species (B. juncea) by RFLP on a genetic map of the recipient (B....
