A REVIEW OF THE GENETICS OF SEED COAT COLOR AND HILUM COLOR IN-FIELD BEANS (VICIA-FABA L. (PARTIM)) WITH COMMENTS ON SOME IMPLICATIONS FOR NATIONAL LISTING AND CERTIFICATION

Variations in results among various workers in the dominance relations hips of some of the alleles controlling seed coat colours in Vicia fab a L. (Partim) have raised the possibility that, in addition to white, other seed coal colours may be controlled by more than one pair of ind ependent genes. In one case, different patterns of segregation were re ported. This may have a bearing on experiments where particular seed c oat colours are associated with specific anti-nutritional factors. Rav e variation in the inheritance of hilum colour is discussed. Possible problems in seed production as a result of inter-crop cross pollinatio n between the two genes for white flower associated with 'white/grey' seed coat colour are identified.
