【摘要】 美国稻种 RA73与 6个不同矮生基因品种进行等位性测定表明 ,其矮生基因不仅与 sd- 1基因不等位 ,也与 sd- s( t)、dg( t)、sd- s( g)、d- 1以及小粒特特普、KL90 8等矮生基因不等位 ,是一个新矮源。更多还原

【Abstract】 RA73 is an American semidwarf mutant derived from the Bonnet 73 of rice. In order to make its allelism clear, a set of crossing test between RA73 and 6 varieties carrying different semidwarf genes were conducted. The result showed that RA73 is not only non allelic to semidwarf gene sd 1, but also non allelic to sd s(t), dg(t), sd s(g), d 1 genes and unknown semidwarf genes carried by Xiaoli tetep and KL908. So it is recognized to be a new semidwarf resource.更多还原
