过去,我们曾经报道,属于所谓爪哇型的印度尼西亚水稻品种,按其与一组籼型和粳型测验种杂交F_1表现的不育关系讲,可以分成若干种不同类型。首先,通过本研究看到这些不同类型间的F_1植株除少数不育外,大多数是可育的。其次。为探索penuh BaruⅡ品种和籼型或粳型测验种间F_1杂种不育的遗传基础,我们做了涉及penuh BaruⅡ,广亲和品种KetanNangka和IR_(30)或IR_(50)(籼型测验种)的三交试验。三交后代表明,小穗育性与某些遗传标记有联系。小穗育性的分离方式利用一个位点等位基因互作的模式得到了解释。认定粳型测验种和penuh BaruⅡ
In the past, we have reported that the Indonesian rice cultivars belonging to the so-called Javanese type can be divided into several different types according to their sterility relationship with F1 hybrids with indica and japonica test varieties. First of all, it can be seen from the present study that F_1 plants of these different types are mostly fertile except for a few infertility. Second. In order to explore the genetic basis of F_1 hybrid sterility between Penuh BaruⅡand indica or japonica test cultivars, we conducted a series of experiments involving penuh BaruⅡ, KetanNangka and IR_ (30) or IR_ (50) Three-handed test. Three generations after the cross shows that spikelet fertility and some genetic markers are linked. Spikelet fertility segregation patterns are explained by the pattern of allelic interaction at one locus. Identified japonica test species and penuh Baru Ⅱ
