粳稻杂种早期世代产量性状选择效果研究

Selection effects of grain yield and nitrogen use efficiency (NUE)in earlier generation were studied under N-fertilized and N-unfertilized conditions using two crosses of Dasanbyeo/IR66746-76-3-2 and TR22183/IR66167-27-5-6.

利用“Dasanbyeo/IR6 6 74 6 2 6 3 2”和“TR2 2 183/IR6 6 16 7 2 7 5 6”两个杂交组合探讨了在施氮和未施氮条件下杂交早期世代对产量及氮素利用效率的选择效果。

６蒙特卡罗模拟，作为一种唯象的研究，对于ＬＨＣＰＰ对撞中来自Ｈ→ｒ＋ｒ－，Ｄｒｅｌｌ－Ｙａｎ，以及ｔｔ和Ｗ＋Ｗ－过程的ｅμ事例，用一具有多个输出网点的前馈式神经元网络进行鉴别，对各物理过程均获得了满意的选择效率和本底压低水平。

To study the selection efficiency for 5 traits selected in the swine breeding plan by LE,LD and DR marker in MAS and GAS in 5 discrete generations,respectively,3 closed nucleus base populations were designed: 100,200,300 sows,and 10 boars each population,where the pigs were unrelated.

结果表明,利用DR标记在各种情况下都比利用LD和LE标记获得的选择效率高;5个性状中,MAS对低遗传力、限性性状NBA的选择效率最高;当性状的QTL方差占遗传方差基本相同时,中等遗传力性状FCR的选择效率比高遗传力性状BF的更高;当性状的遗传力差异不大时,QTL方差占遗传方差比例大的性状FCR的选择效率比QTL方差占遗传方差比例小的性状ADG的更高。
