在点播的F_2代,采用含有共同母本“Gelenlea”的三个春小麦(Tritcum aestivum L.)杂种,在众多的选择标准中评价了把生产率、产量指数和株高用作选择标准以便识别出高产的F_4代集团的价值。试验表明,利用生产率这一指标能从点播的群体中选出具有高产潜力的高秆品种;而利用产量指数这一指标能从点播的群体中选出半矮秆(矮秆)品种。因此,对于选择具有高产潜力的品种来说,对高秆的F_2代植株可把生产率作为选择标准;对矮秆的F_2代植株可把产量指数作为选择标准。这些结果表明,把生产率、产量指数和株高结合起来进行春小麦的产量选择,是很有用的。
In the on-demand F2 generation, the three triticale (Triticum aestivum L.) hybrids containing the common mother “Gelenlea” were evaluated in many selection criteria using productivity, yield index and plant height as selection criteria to identify high yield The value of F_4 generation group. Experiments show that using the index of productivity can select the high-stalk varieties with high yield potential from the on-demand groups, while using the index of the yield index can select the semi-dwarf (dwarf) varieties from the on-demand groups. Therefore, for the selection of cultivars with high yield potential, the production rate could be taken as the selection criterion for the high-yield F2 generation plants and the yield index for the dwarf F2 generation plants as the selection criterion. These results indicate that it is useful to combine the productivity, yield index and plant height for spring wheat yield selection.
