以华仁杏6个杂交组合为实验材料,利用SSR分子标记技术研究亲本与杂种扩增谱带的多态性,以甄别真假杂种。筛选出在亲本和杂种之间存在双亲互补带型的引物6对,除2个杂种无法鉴别外,其余品种均可鉴别为真杂种。另外亲缘关系和遗传变异分析结果表明,各个组合杂交后代表现出来的一致性较高,遗传多样性水平相差不大,但当父本选择X1时,母本选择H1或H3杂交后代差异比较显著。

The transferability of 53 pairs of self-incompatible S-RNase genotype identification primers from Rosaceae to kernel-apricot was analyzed in order to provide theoretical reference for S-RNase genotype identification and cross breeding work of kernel-apricot. The results showed that only 12 out of 53 primers had good transferability in kernel-apricot which could be used in S-RNase genotype identification. There was a higher transferability in kernel-apricot of Prunoideae than Maloideae, but the highest was in Armeniaca.
