【摘要】用15个粳型亲籼系分别与2个籼型光(温)敏核不育系W9593S、GD-
8S和2个粳型光(温)敏核不育系N5088S、N8819S进行了亲和性测定.结果表明,粳型亲籼系与籼型光(温)敏核不育系和粳型光(温)敏核不育系的亲和性都较高.平均花粉育性分别为74.71%、79.21%、78.27%和84.66%,平均小穗育性分别为57.52%、72.43%、57.23%和51.86%.就花粉育性而言,粳型亲籼系与粳型光(温)敏核不育系的亲和性略优于籼型光(温)敏核不育系:就花小穗育性而言,粳型亲籼系与籼型光(温)敏核不育系的亲和性略优于粳型光(温)敏核不育系.IC3-5-2-1-2、
IC3-11-2、IC9-9-1-1与W9593S亲和性高;IC2-1-1-3-3、IC3-5-2-1-1、
G2417-2-1与GD-8S亲和性高;IC10-4、IC10-9-3-3与粳型光(温)敏核不育系亲和性高,说明粳型亲籼系与籼、粳光(温)敏核不育系还存在特异亲和性.%The compatibility was tested between 15 indica-compatible japonica lines and 2 indica PTGMS lines(W9593S,GD-8S)as well as 2 iaponica PTGMS
lines(N5088S,N8819S).The results indicated that the compatibility between indica-compatible japoniea lines and indica PTGMS lines as well as japeniea PtGMS Wag good.The average fertility rates of pollen were
74.71%,79.21%,78.27%and 84.66%respectively,and the average fertility rates of spikelet were 57.52%.72.43%,57.23%and 5 1.86%respectively.As for the fertility rate of pollen,the compatibility between indica-compatible
japonica lines and japonica PTGMS lines Wag a little better than it between indica-compatible japonica lines and indica PTGMS lines.As for the fertility rate of spikelet.the compatibility between indica-compatible iaponica lines and indica PTGMS lines was a lit-tle better than it between indica-compatible japoniea lines and japonica pTGMS lines.High compatibilities were observed 8S,and between IC10-4、IC10-9-3-3 and iaponica PTGMS lines.It indicated that there were specific compatibilities be-tween indica-compatible iaponiea lines and iaponica PTGMS lines as well as indica PTGMS lines.
