硬粒小麦SWAHEN 3成株期对中国条锈病新小种条中30(CYR30)和条中31(CYR31)免疫-高抗。为明确SWAHEN 3抗条锈性状的遗传规律，将SWAHEN 3与高感硬粒小麦品种Kappli杂交，获得杂种F1、F2群体；将SWAHEN 3与川育12等5个四川高感普通小麦品种杂交，获得杂种F1。对抗×感硬粒小麦杂种F1、F2群体分小种(CYR30和CYR31)接种鉴定，结果表明，杂种F1抗性反应与抗病亲本SWAHEN 3一致，为免疫-高抗；杂种F2群体中免疫-高抗单株与抗-高感单株之比符合两对显性互补基因分离比例9∶7。对抗病硬粒小麦×感病普通小麦杂种F1分小种(CYR30和CYR31)接种鉴定，结果表明，杂种F1抗性反应也与抗病亲本SWAHEN 3一致，为免疫-高抗。分析表明，SWAHEN 3对条中30、31的抗性受两对显性互补基因控制，其抗性基因能在与四川高产小麦的杂交后代中完全表达。

SWAHEN 3, a durum wheat line introduced from CIMMYT, was highly resistant to Chinese new stripe rust races CYR30 and CYR31 at adult stage. In order to determince the inheritance of resistance in it, SWAHEN 3 was crossed with a highly susceptible durum variety Kappli and five highly susceptible cultivars of Sichuan common wheat. Analysis of data from F1～F2 of cross between SWAHEN 3 and Kappli revealed that the resistance to CYR30 and CYR31 of SWAHEN 3 was controlled by two complementary dominant genes. And all of F1 hybrids of SWAHEN 3 crossed with five Sichuan common wheat cultivars were immune to the two Chinese stripe rust races. This result could indicated the resistance of SWAHEN 3 could be expressed in common wheat.
