It is very important to recognize genetic variations in the seed production characteristics of radish (Raphanus sativus L.), because, based on the land area devoted to cultivation and the number of local varieties, radish is one of the most common Japanese vegetables. We used 219 lines, belonging to 23 varietal groups, of cultivated radishes and examined 3 seed productioncharacteristics: the self-incompatibility alleles (S-alleles), the level of self-incompatibility and the number of seeds per pod in bud pollination. Thirty-seven S-alleles, designated as S²⁰¹ to S²³⁷, were identified by cross pollination tests and PCR-RFLP. These varietal groups were classified by principal component analysis, based on the similarity of the S-alleles calculated by quantification method IV. The classification of the varietal groups in these experiments did not correspond to that based on the morphological characteristics or geographical distribution of the local varieties. Thus, the tests revealed that the S-gene is not correlated with the phyletic diversification of Japanese cultivated radishes. The level of self-incompatibility (SI) was evaluated by the rate of self-seed setting, i. e. the number of pods setting seed/the number of flowers artificially self-pollinated in anthesis×100 (%). The level of SI in these lines ranged from 0 to 100 %. However, there was no correlation within these varietal groups in this characteristic as well as in the S-alleles. The number of seeds per pod ranged from 0.9 to 6.2 seeds. No correlation among the above characteristics was detected. In conclusion, we considered the importance of seed production characteristics in the evaluation of radish germplasm collection and suggest that the breeders should pay attention to the selection of these characteristics.
