用矮变1号与农林10号小麦矮源,分别以同样的组配方式进行正反交试验。结果表明:(1)矮变1号株高的遗传,不同于农林10号的隐性遗传方式,可认为控制矮变1号株高遗传的主要矮化基因是部分显性的;(2)矮变1号各组合子二代分离出超矮秆植株的比例显著大于农林10号;(3)相关性分析表明,杂种后代随着株高的降低,不孕小穗增加,主穗粒数减少,穗粒重和株粒重明显下降。但是,不同杂交组合的表现不尽相同。“矮变1号”ד8582-201”,子二代平均株高44.7厘米,在田间以矮、齐、多穗而注目,杂种穗粒性状的表现也比较突出。
Using short dwarfing No.1 and Nonglin10 dwarfing wheat, the same combination method was used to carry out the reciprocal crossing test. The results showed that: (1) The inheritance of plant height of Dwarfing No.1 was different from that of Hailin10. The dominant dwarfing gene controlling the height of Dwarfing No.1 was partially dominant; (2) (3) The correlation analysis showed that the offspring of hybrids with increasing plant height, spikelets increased, the number of main grains per spike Reduce, grain weight per ear and grain weight decreased significantly. However, the performance of different crosses is different. “Dwarf No. 1” × “8582-201”, the average height of the second generation was 44.7 cm. In the field, dwarf, homogeneous and multi-spike were the focus, and the performance of the hybrid spikelet was also outstanding.
