摘要

为了使大豆品种得到广泛应用,希望它们不含库尼茨胰蛋白酶抑制剂(Kti),并对黄花叶病(YMD)具有抗性。将具有YMD抗性的大豆品种SL525与具有空kti等位基因的YMD易感品种NRC101杂交。用两个SSR标记(satt409和satt322)分别与空kti等位基因和抗YMD基因连锁,以及一个空kti等位基因特异性标记对F5后代进行筛选。表型数据进一步证实了这两个理想性状的存在,表型数据与基因型数据显示出良好的相关性。这14个基因型的产量潜力与SL525相当或优于SL525,因此是SL525的改良版本。

Combining the null Kunitz trypsin inhibitor and yellow mosaic disease resistance in soybean (Glycine max (L.) Merrill)
For the wide adoption of soybean varieties, it is desirable, that they are Kunitz trypsin inhibitor (Kti) free and resistant to yellow mosaic disease (YMD). The soybean variety SL525 with YMD resistance was crossed with the YMD susceptible variety NRC101 with a null kti allele. The F5 progeny derived from the cross was screened with two simple sequence repeat (SSR) markers (satt409 and satt322) linked with the null kti allele and the YMD resistance, respectively, and one null kti allele-specific marker. The presence of both desirable traits was further confirmed with the phenotypic data which showed good correlation with the genotypic data. The yield potential of fourteen such identified genotypes having both desirable traits was either at par or superior to SL525, hence, represent improved versions of SL 525.
