摘要:
为拓宽玉米种质遗传基础，黑龙江省农业科学院齐齐哈尔分院采用20份美国玉米种质选育的48份中晚熟优良玉米自交系为试验材料，以NSS群自交系N8942，SS群自交系N79232为测验种，采用NCⅡ遗传交配设计组配96份杂交组合，进行单株产量一般配合力及特殊配合力分析。结果表明：48份优良自交系的一般配合力（P1）F=0.930 6，差异不显著（P=0.596 8）；特殊配合力(P1×P2)间的F=2.824 8，差异极显著（P=0.000 1），NMX02-5212和NMX11-3321的一般配合力和特殊配合力都较高。48份自交系中，偏向于NSS群的共计29份，包括NMX02-212、NMX02-2231、NMX03-124等；偏向于SS群的共计19份，包括NMX02-5212、NMX02-6233、NMX04-23211等。96份杂交组合的小区产量平均对照优势为正值的有27份，占全部组合数的28.13%，较对照优势表现突出的组合为NMX11-3321×N8942、NMX18-122×N8942和NMX11-1111×N79232，小区产量均超过对照5%以上，最高6.21%，NMX11-3321、NMX18-122、NMX11-1111这3份自交系育种潜力较大。
Abstract:
In order to broaden the genetic basis of maize germplasm,the Qiqihar Branch of Heilongjiang Academy of Agricultural Sciences used 48 medium-late mature maize inbred lines selected from 20 US maize germplasms as experimental materials,and NSS group inbred lines N8942,SS group inbred lines.N79232 was used as a test species.The NCII genetic mating design was combined with 96 hybrid combinations to analyze the general combining ability and special combining ability analysis of individual plants.The results showed that the general combining ability (P1)F=0.930 6 of 48 excellent inbred lines was not significant (P=0.596 8)；The F value of the special combining ability (P1×P2) was 2.824 8,and the difference was extremely significant (P=0.000 1).NMX02-5212 and NMX11-3321 had higher general combining ability and special combining ability.In the 48 inbred lines,29 were partial to the NSS group，including NMX02-212,NMX02-2231,NMX03-124,etc.；A total of 19 parts were biased toward the SS group,including NMX02-5212,NMX02-6233,NMX04-23211,and the like.The average yield advantage of the yield of 96 hybrid combination was 27,accounting for 28.13% of the total combination.The combination with outstanding performance advantages was NMX11-3321×N8942,NMX18-122×N8942 and NMX11-1111×N79232.The yield of the plots exceeded 5% of the control and the highest was 6.21%,inbred lines NMX11-3321,NMX18-122,NMX11-1111 have great potential for breeding.
