为了得到分蘖数、种子大小、每穗粒数和籽粒产量方面的遗传资料,在印度旁遮普Lud—hiana旁遮普农业大学研究WG357×Tobari66的春性小麦品种间杂交的早期分离世代。研究了亲本、F_1、F_2、B_1、B_2、双亲本、F_3(双亲本的亲代)、F_3集团和F_4集团以提供世代平均值分析和变量组成分析。在本研究中证明了轮回选择对性状改良的利用是有限的。遗传上,加性基因作用占优势,特别在产量组成上。因此,在分离世代中简单的育种程序对产量组成的改良可能是最有用的。
In order to obtain genetic information on tiller number, seed size, grain number per panicle and grain yield, the early segregation generation of spring wheat varieties of WG357 × Tobari66 was studied at Punjab Agricultural University in Ludhiana, Punjab, India. The parents, F_1, F_2, B_1, B_2, parents, F_3 (parents of parents), F_3 and F_4 groups were studied to provide generation mean analysis and variable composition analysis. It is demonstrated in this study that the use of recurrent selection for trait modification is limited. Genetically, the role of additive genes dominates, especially in the composition of the output. Therefore, simple breeding programs in the isolated generation may be most useful for improving yield components.
