89—28 利用自交系的自交亲和性配制品系间杂种Plant Breeding Abstracts.1988.(58)9:845,已研究的甜菜自交系多数是自交不亲和的。利用带有遗传标记的品系测定其纯合度,杂交以后,可以识别出杂种。仅在部分自交亲和的品系中,发现自交系的自交亲和性与其本身的杂合性存在负相关。无论是在自交亲和的品系还是在自交不亲和的品系中,均未发现类似 89-28 Inbred Lines Using Inbred Lines to Inbred Hybrids Plant Breeding Abstracts.1988. (58) 9: 845, most of the beet inbred lines studied have been self-incompatible. The homozygosity was measured using lines with genetic markers and hybrids were identified after hybridization. Only in partially self-compatible lines, it was found that there was a negative correlation between inbreeding self-compatibility and its own heterozygosity. No similar inbred lines or self-incompatible lines were found
