筆者綜述了雜種優(yōu)勢遺傳基礎的兩個經(jīng)典假說-顯性假說和超顯性假說的基本觀點、不足之處。
In Population H21 Mol7, nine QTL were detected for resistance to ACB, which were localized on chromosome 1,4,5,8 and 10. These QTL showed predominantly overdominance, subsequently dominance or partial dominance gene action.
對H21×Mo17群體，共檢測到9個抗性QTL，分別位于染色體1、4、5、8、10上，表現(xiàn)的基因效應以超顯性為主，此外還有顯性效應和部分顯性。
In Population ZJ330XK36, eight QTL were detected for resistance to ACB, which were localized on chromosome 1,2,3,4,5,8 and 9. These QTL showed overdominance, dominance, partial dominance and additive gene action.
對自330×K36群體，共檢測到8個QTL，分別位于染色體1、2、3、4、5、8和9上。這些QTL表現(xiàn)的遺傳效應涉及超顯性、顯性效應、部分顯性和加性效應。
