Is the P gene in common bean located in linkage group VII?
1988
Bassett, M.J. | Awuma, K.
Linkage tests in common bean (Phaseolus vulgaris L.) were made between black-seeded lines carrying the marker genes round leaf (rnd) and stipelless lanceolate leaf (sl) and the white-seeded lines 'Miami' and 'Inepuisable' and an induced mutant for white seed, 3-254. The crosses 'Miami' X 'Inepuisable' and 'Miami' X 3-254 were made to test for allelism of the white seed genes in these lines. 'Miami' was found to be allelic to 'Inepuisable' and 3-254 at the white seed locus (presumed to be P). Furthermore, there was no indication of linkage between the white seed locus and the markers rnd and sl. These results contradict expectations of linkage of P with rnd and sl based on previously published linkage maps and indicate that the present map position of P is incorrect.
