为了进一步理解遗传学的基本规律,克服育种盲目性,提高育种成效,摸清水稻的遗传规律,1980年我们进行了不同生态类型的早、晚稻品种间的杂交F_2代的遗传规律研究,现将试验报告如下。一、试验材料和方法供试验的两个不同的生态型水稻品种是“红410”(早稻、矮秆、稃尖紫红色、翻秋成熟10月9日)和“浙场9号”(晚稻、高秆、稃尖无色、中熟偏迟)。观察分析其正反交F_2代的性状遗传变异。试验于6月27日播种,7月25日移栽,秧龄28天。以亲本为对
In order to further understand the basic rules of genetics, to overcome the blindness of breeding, improve the breeding effect and find out the genetic law of rice, we carried out the genetic law of F_2 generation between hybrid rice varieties of early and late rice with different ecological types in 1980. The test report is as follows. First, the test materials and methods for the test of two different ecological rice varieties are “red 410” (early rice, dwarf, spire purple color, ripe autumn October 9) and “Zhejiang field 9” (late rice , Tall stalk, tip sharp, late maturity). Observation and analysis of the reciprocal crosses F_2 generation of genetic variation of traits. The experiment was sown on June 27, transplanted on July 25, and the seedling age was 28 days. The parents are right
