Mapping of microsatellite markers in two wheat crosses segregating for Pm23 and Pm4b, respectively, in combination with the reported mapping of Pm4a, indicated that the three genes were all linked to the marker Xgwm356 with a distance of 3-5 cM. Allelism between Pm4b and Pm23 was then confirmed, when the progenies of a cross between VPM1 (Pm4b) and Line 81-7241, were shown to be all resistant to a B.
利用获得的8个标记对Pm4b进行遗传作图,结果表明,4个标记与Pm4b连锁(Xgwm356、Xgdm93、Xbar76和Xbarc122)。3个抗白粉病基因(Pm4a、Pm4b和Pm23)均与标记Xgwm356连锁,遗传距离为3-5cM,等位性测验证明Pm23与Pm4b为等位基因。

The allelic diversity in terms of number of alleles per locus and expected heterozygosities in cultured populations N=8.0-9.4, H(subscript e=0.754-0.787 was considerably lower than that found in the wild populations N=11.3-15.0, H(subscript e=0.821-0.866. Allele distributions at all seven microsatellites indicated that the cultured populations lost some rare alleles belonging to wild populations. The small number and the biased sex ratio of abalone for hatchery broodstock might be responsible for the remarkable reduction of genetic variation in the studied populations.
结果表明,从等位基因数与杂合度上分析,养殖群体(N=8.0~9.4, H=0.754~0.787)遗传多样性显著低于野生群体N=11.3~15.0, H(下标 e=0.821~0.866;等位基因频率分布揭示出野生群体中一些稀有等位基因在养殖群体中有所丢失;亲鲍选用数量少与性别比例不均衡可能是产生养殖群体中遗传多样性显著减少的原因。
