8个糯玉米自交系的配合力分析

摘要

采用不完全双列杂交设计,对重庆市选育的8个糯玉米自交系主要性状进行配合力效应分析.结果表明:不同自交系所表现的配合力不同,同一自交系不同性状间和同一性状不同自交系同的配合力存在一定差异；自交系S181和N805是较好的亲本,可配制出高产的优良组合.%With incomplete diallel crossing design, the combining ability effects of the main yield components in waxy maize inbred in Chongqing was analyzed. Results showed that various inbred lines had different combining abilities, or even various traits in an individual line or the same trait between lines also showed some difference. Two inbred lines S181, N80S were evaluated as fairly good parents, so could be used to make fine high-yield combinations.
