为了有效地选育小麦矮杆品种,我们初步探讨了杂种后代株高的遗传特点,作为第二代选择矮杆类型以及选配亲本的参考。本试验选用十六个组合的材料。73年春观察记载F_1的表现,株数依各组合材料多少而定。74年春测定了F_2株高,每组合200株,亲本各30株左右。现将结果整理如下:
In order to breed wheat dwarf varieties effectively, we first discussed the genetic characteristics of the hybrid offspring plant height as a second-generation selection dwarf rod type and optional parent reference. This test uses a combination of sixteen materials. 73 years of spring observed the performance of F_1, the number of strains depending on the number of combinations of materials. In the spring of 74, F_2 plant height was determined, with 200 plants in each group and about 30 parents each. The results are now organized as follows:
