原始语种摘要: The newly identified SSR marker AVRDC-PP12 linked to the male sterility gene ms10 distinguished the heterozygous ( Ms10ms10 ) fertile from the homozygous ( Ms10Ms10 ) fertile plants in chilli segregating populations. To assess efficiency of AVRDC-PP12 in marker-assisted backcrossing for transfer of ms10 gene; the marker was screened in four backcross progenies. The marker co-segregated with ms10 gene in three progenies derived from the crosses ‘MS-12 × VR-16’, ‘MS-12 × S-217621’ and ‘MS-12 × Selection Dev’ with recombination frequency of 3.22, 4.16 and 3.27%, respectively. The marker failed to differentiate the parents in the cross ‘MS-12 × DCL-524’and hence was not used for further genotyping of the population.
