查询词典 dominant weight

In this research, the ~ and F2 of the crosses between a natural mutant 慪34?with super-minute grain and 慪38?with super-large grain,慡huhui 881擲huhui 527?with middle grain size were carried out to study the inheritance of the grain shape (grain length, grain width, grain thickness and grain length/width ratio) and 1000-grain weight. The main results are summarized as below:? The F1 grain length, grain width, grain thickness and 1000-grain weight of three crosses were lay between the two parents and tended to Y34, which indicated that those grain traits were all governed by the dominant effect of Y34 and influenced by both female and male parents. The differences of F1 grain length, grain width, grain thickness and 1000-grain weight of positive and negative crosses between Y38 and Y34 indicated the existence of cytogene effects.? The broad heritabilities of major grain traits were calculated.

本研究利用一份水稻极小粒自然突变材料Y34与一份水稻极大粒材料Y38、两份常规籽粒大小材料蜀恢881、蜀恢527的杂交F_1及F_2，对主要粒形性状（粒长、粒宽、粒厚、长宽比）及千粒重进行了遗传研究，根据遗传研究的结果利用微卫星标记结合F_2群分法对控制Y34短粒性状基因进行了分子标记定位，主要结果如下：●各组合F_1粒长、粒宽、粒厚和千粒重介于双亲之间且明显偏向于小值亲本 Y34，这表明粒长、粒宽、粒厚和千粒重均主要受小值亲本显性基因的控制并同时也受大值亲本核基因的影响。Y34与Y38正反交F_1在粒长、粒宽、粒厚、千粒重等性状上存在差异，表明存在细胞质效应。

The effect of transgenx Bt cotton on non-target insects The kinds of the dominant species of pests in transgenic cotton field had obvious change, in which the H. armigera was no longer the main pest and the piercing-sucking pests such as Aphis gossypii, Tetranychus urticae, Thrips tabaci etc. rose the main pests. The kinds of the dominant species of predatory natural enemies seemed to be no variation, which was still Propylaea japonica Thunberg. Because of the effect of transgenic Bt cotton on H. armigera laevae-the development delay, the weight reduction, which affected the qualities of parasitic enemies, leading to the reduction of the weight of cocoon and the weight of adult, and the reduction of H.
