摘　　要：矮泰引－２中半矮秆基因的分离与鉴定研究梁国华，潘学彪，顾铭洪，嵇朝球（扬州大学农学院农学系，扬州２２５００１，现在地址：江苏油田农场，江苏洪泽２２３１２５）关键词：基因分析；基因分离；半矮秆基因ＴｈｅＩｓｏｌａｔｉｏｎａｎｄＧｅｎｅｔｉｃＩｄｅｎｔｉ...In order to discover new semidwarf genes which can be used in breeding program in indica rice, a dwarf variety f Aitaiyin 2, was crossed with a tall native cultivar Naming 6. The segregation of the F, generation appeared to be 9 tall: 6 semidwarf: 1 dwarf, which meant two semidwarf genes were involved. While Aitaiyin 2 was also crossed with two semidwarf varieties, Nanjing 11 with sd-1 and Xingui'ai with sd-g, the segregation of the F2 generation in the former cross was 3 semidwarf: 1 dwarf and that in the latter cross was 27 tall: 27 semidwarf: 9 dwarf: 1 extra dwarf. This indicated that there were two semidwarf genes in Aitaiyin 2, one of them was allelic to sd-1 and the other was a new semidwarf gene which was nonallelic to both sd-1 and sd-g.This new semidwarf gene was named sd-t(t).
