摘　　要：通过对转基因恢复系转ipt R527和金23A杂交后代F1群体的DNA检测,检测到杂种F1群体中阳性植株和阴性植株的比例为7∶1,不符合孟德尔规律;考察了转ipt R527和金23A杂种F1的株高、单株产量、结实率、千粒重、穗长、穗粒数、穗数等7个性状,与对照(金优527)相比,结实率、千粒重、穗长高于对照,单株产量、穗粒数、穗数低于对照,农艺性状间的相关分析表明,千粒重和穗数是影响转基因杂种F1单株产量的重要因素。The ratio of positive and negative plants of F1 generation of R527（Transgenic ipt）×Jin23A is 7∶1 by DNA testing,which do not accord with the Mendelian laws.Their seed setting rate,1000-grain weight and spike length are higher than Jin23A and their yield per plant,kernels per spike and effective spike number are lower than Jin23A.The correlation analysis of agronomic traits show that 1000-grain weight and effective spike number are the most important factors to affect yield per plant of F1 generation.
