Glycim e soja 被认为是 Y M V(黄化花叶病毒)和 B H C(棉灯蛾)的野生抗源,通过 Glycine m ax 和 Glycinesoja 种间杂交研究了 Y M V、 B H C、 B P(大豆细菌性斑疹病)与抗性之间的基因连锁。结果表明只有 Y M V 抗性与 B P感病之间是连锁的(显著偏离9:3:3:1)。用平方根法、 Product ratio 法, Em erson 法和极大似然法四种方法估算了这对性状之间的重组值。所有组合、四种方法的总平均重组值为 29.05% ,表明这两个基因(性状)间有着不太紧密连锁(重组值不等于图距)。这样的连锁强度应不难得到对 Y M V 和 B P均抗的重组型。
Glycim e soja is considered as a wild anti-source of Y M V (yellow mosaic virus) and B H C (cotton budworm). YM V, B H C, B P ( Soybean bacterial disease) and genetic linkage between the resistance. The results showed that only the linkage between Y M V resistance and B P susceptibility was significant (significant deviation from 9: 3: 3: 1). The square root method, Product ratio method, Em erson method and maximum likelihood method were used to estimate the recombination value between these traits. The total average recombination value for all combinations and the four methods was 29.05%, indicating that the two genes (traits) are not very closely linked (recombination value is not equal to the distance). Such a linkage strength should not be difficult to obtain a recombinant that is resistant to both Y M V and B P.
