蔷薇科S-RNase基因型鉴定引物在仁用杏基因组中的通用性分析

Transferability of S-RNase Genotype Identification Primers from Rosaceae to Kernel-apricot

仁用杏为我国六大木本粮油战略性树种之一，是“三北”地区适应性最强、发展潜力最大的重要生态经济树种之一，被誉为“铁杆庄稼”，其抗逆性强，也是集抗旱、抗寒（可低至-35℃）、抗风沙为一体的“先锋”树种。杏仁油中不饱和脂肪酸含量95％左右，其中单不饱和脂肪酸——油酸含量在70％以上，与橄榄油相近，富含丰富的蛋白质、不饱和脂肪酸、维生素、无机盐、膳食纤维及人体所需的微量元素，而且杏仁油还含有一定的异油酸，具有降血脂、调节血压、辅助治疗心脑血管疾病功效，苦杏仁甙更是公认的天然抗癌活性物质。可见，仁用杏蕴藏着巨大的产品开发潜力，应用前景十分广阔。

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.
