Marker-assisted selection for temporary maintainers of a recessive epistemic genic male sterility in Brassica napus L

Four varieties of Brassica napus, Xiangyou 15, Huyou 15, You 88 and Huyou 17, were crossed with a temporary maintainer (TAM) named HYZ1-TAM respectively and produced four F<sub>2</sub> populations. In these populations, molecular markers associated with Bnms3 and Bnrf were used to select...

Description
Summary:Four varieties of Brassica napus, Xiangyou 15, Huyou 15, You 88 and Huyou 17, were crossed with a temporary maintainer (TAM) named HYZ1-TAM respectively and produced four F<sub>2</sub> populations. In these populations, molecular markers associated with Bnms3 and Bnrf were used to select new temporary maintainer plants which were identified by test-cross. Sixty-two plants with TAM marker-genotype were selected by marker-assisted selection (MAS) from three hundred and fifty-five plants of four F<sub>2</sub> populations. Fifty-seven plants (with the accuracy of 91.94%) were TAM genotype proved by test-cross. Compared with traditional method, it is very efficient to select TAM by MAS. In the Bnms4 locus, all the four varieties have a same genotype which is ms4ms4.
