摘　　要：以育成的5份糯玉米DH系及其杂交组合为研究材料,分析糯玉米DH系主要品质及农艺性状与我国主要生态地区骨干糯玉米亲本自交系的配合力效应,并对其遗传特性和规律作进一步探讨。结果表明,结合单株产量等8个性状特殊配合力效应表现,15ND 13×景白浚34、15ND 15×JN-2、15ND 14×1211是特殊配合力表现优良的前3个组合。供试糯玉米DH系与黑龙江、山东、北京地区糯玉米骨干自交系较易组配出强优势杂交组合,但与山西和河北地区糯玉米骨干自交系较难组配出高产组合。Based on 5 DH lines of waxy maize and their hybrid combinations as experimental materials, the combining ability effect of main quality and agronomic traits in waxy maize DH lines with the parent inbred lines of waxy maize in main ecological regions of China were analyzed.Also, the genetic characteristics were further discussed.The results indicated that the effect of special combining ability on 8 traits was that the combination 15 ND 13×Jingbaixun 34,15 ND 15× JN-2 and 15 ND 14X 1211 showed excellent on special combining ability.In addition,the experimental waxy maize DH lines were more likely to have a strong heterosis combination with the waxy maize inbred lines in Heilongjiang, Shandong and Beiiing,but it was difficult with the waxy maize inbred lines in Shanxi and Hebei areas.
