以农大高诱1号诱导系和辽3162(大斑病感病材料)×A619HtN(大斑病抗病材料)组配的材料为亲本获得的5个DH(doubled haploid)系与辽3162、A619HtN和中106为父本系组配的15个杂交组合为试材,采用数量遗传学方法进行DH系产量和田间农艺性状的配合力分析。结果表明:诱导DH系的基础材料决定其诱导后代的类型,利用DH育种技术可以快速改良自交系的一般配合力,组配优良的杂交组合。
Five DH (doubled haploid) lines, which were obtained from the induction lines of Nongda Gaoyu 1 and Liaodong 3162 (big leaf disease-sensitive material) × A619HtN (big leaf spot disease-resistant material), were used in combination with Liao 3162, A619HtN Fifty-six cross combinations of parental line and parental line 106 were used as materials to analyze the combining ability of DH lines and field agronomic traits by quantitative genetic method. The results showed that the basic materials inducing DH lines determined the type of induced offspring, DH breeding technology could quickly improve the general combining ability of inbred lines, with excellent hybrid combinations.
