To determine the inheritance of resistance in Chuanmai 42, it was crossed and backcrossed with the susceptible Sichuan varieties of common wheat Mianyang 26 (MY26) and Mianyang 335 (MY335) for preparing the F2 and BC1 populations. A total of 208 and 337 F2 plants of Chuanmai 42×MY26,Chuanmai 42×MY335, and 171 and 216 BC1 plants of Chuanmai 42/MY26//MY26,Chuanmai 42/MY335//MY335, respectively, were used for resistance analyses.

为明确川麦42抗条锈性遗传基础，将川麦42分别与高感条锈小麦品种绵阳26、绵阳335杂交和回交，获得杂交F1、F2、BC1群体，其中，川麦42×绵阳26、川麦42×绵阳335 F2群体分别为208和337株，川麦42/绵阳26//绵阳26、川麦42/绵阳335//绵阳335 BC1群体分别为171和216株用于抗性遗传分析。

In this study, genetic analyses were conducted to determine the genetic basis in an elite resistant inbred line Siyi with complete resistance to maize dwarf mosaic. A new genetic model, two dominant complementary genes conditioning the resistance, were found by Mendelian genetic analysis based on parents, F1, F2 and backcrosses in three successive years' field trails. The two genes were further mapped near the centromere of chromosome 3 and 6, respectively by tightly linked microsatellite markers using 242 plants from F2 generation. The resistance gene on chromosome 3 is 1.0 cM apart from the flanking markers phi053 and umc1527, respectively. Whereas the linkage distance between two flanking markers bnlg1600 and phi075 and resistance gene on chromosome 6 was 1.0 and 4.0 cM, respectively. Genotypic analysis of the plants from testcross and F3 populations supported the new genetic manners.

课题组通过连续三年的抗病鉴定，在国内种质资源中筛选出一份综合农艺性状优良、配合力较高的自交系四一，三年的表型遗传研究和两年的分子标记工作，发现四一中的玉米矮花叶病抗性是由两对显性互补基因控制的，进而利用F2作图群体，把发现的两个基因定位在第三和第六染色体的着丝点附近，并获得了双侧紧密连锁的分子标记连锁图谱，其中第三染色体上的分子标记UMC1527和phi053从抗病基因双侧逼近1 cM，而第六染色体上的分子标记phi075、bnlg1600从抗病基因双侧分别逼近4 cM和1 cM；利用B2群体、F2：3家系、BC3F1群体和带有第三、第六染色体抗病基因以及两个抗病基因的近等基因系，进一步证实了四一中成株期抗性是由两个显性互补基因控制的。
