摘要： 研究了云南稻种矮源雪禾矮早的矮秆基因sd-s (t)与20个已知矮秆基因以及与2个标记基因gh-1和st-t间的关系。结果表明，sd-s(t)与d-2、d-3、d-6、d-7、d-10、d-11、d-14、d-17、d-18h、d-19、d-27、d-30、 d-35、d-42 、d-47、d-51、d-52 等19个矮秆基因为非等位关系，而与d-1可能为复等位关系。建议将sd-s(t)命名为 d-1x。 该复等位基因系列的显隐关系为+>d-1x>d-1. 在第VI+IX连锁群上的d-1x与gh-1的交换值为33%±5.6%，与st-2的交换值为23%±6.1% gh-1与st-2的 的交换值为48%±4.7%，即d-1x位于gh-1和st-2两个标记基因之间。

Abstract: The research deals with the relation of the dwarf gene sd-s(t) presenting in Yunnan rice variety Xueheaizao, with 20 known dwarf genes and 2 marker genes gh-1 and st-2 in linkage group Ⅳ+Ⅸ. The results indicated that sd-s(t) was nonallellc to the following dwarf genes: d-2, d-3, d-6, d-7, d-10, d-11, d-12, d-13, d-14, d-17, d-18h, d-19, d-27, d-30, d-35, d-42, d-47, d-51, d-52, but possibly a multiple allele to d-1. It suggests that the gene symbol sd-s (t) be renamed as d-1x. The dominance order of these multiple alleles is+>d-1x>d-1. The recombination value between d-1x and gh-1 is 33%+5.6%, that between d-1x and st-2 is 23%±6.1%, while a 48%+4.7% recombination occurs between gh-1 and st-2, indicating that d-1x locus is between gh-1 and st-2 loci in linkage group Ⅵ+Ⅸ.
