【摘要】 采用ＮＣⅡ设计，用３个自交系和２个单交种测定中综３号８个改良群体的一般配合力。结果表明，单交种测验效果优于自交系测验效果。大多数性状上２个单交种测定结果与５个测验种总体测定结果高度正相关；３个自交系测验结果与总体测验结果之间在产量和果穗性状上相关性不显著。测验种一般配合力高低与测验效果呈不显著负相关。更多还原

【Abstract】 By using NC Ⅱ design,3 inbred-lines and 2 single crosses were used as test varieties to investigatethe general combining ability of 8 recurrent maize im proved population of Zhongzong 3. The test re-sult and their relationships with the relatedtraits were analysed. The results indicated that :(1) Thetest effect of single cross was superior to that of inbred lines.(2 ) In the most of agronomy traits, thetest results of general combining ability. using single crosses as tester were highly positively correlatedwith that of the total test results using 5 testers including 3 inbred lines and 2 single crosses.(3)In theyield traits and the ear traits , the correlation between the test results of3 inbred lines and that of the 5totaI testers was not significan(4 ) The correlation between general combining ability of tester andtest effect、vas not significantly negative.更多还原
