水稻糯质的遗传规律,据有关研究报道,都认为是属于隐性基因控制的隐性性状,而非糯性则是由显性基因控制的显性性状。根据遗传一般规律,糯稻与非糯稻杂交(无论正反交),其当代母本上杂交的颖花上结的种子(F_0)的性状应为母本的性状。杂种一代(F_1)的基因型是杂合型,性状上应显示显性性状(对完全显性而言)。但我们在杂交育种实践 The genetic law of waxy rice, according to relevant research reports, are considered recessive traits of recessive genes, whereas non-waxy genes are dominated by dominant genes. According to the general rule of inheritance, the hybrid (non-reciprocal crossing) of glutinous rice and non-glutinous rice, the character of the seed (F_0) of the hybrid of the current female parent should be the female parent. The genotype of the hybrid F1 (F_1) is heterozygous and traits should show dominant traits (for complete dominance). But we practice in hybrid breeding
