研究高粱主要性状的遗传规律,对提高育种成效密切相关。笔者在几年的育种工作中,就高粱的早熟性、矮秆,品质,配合力、抗败育和不育性等方面的遗传育种问题进行了研究,结论如下:1、用早熟亲本,特别是早熟性遗传的亲本与其他早熟、中熟或晚熟亲本组配,只要组配得当,使其早熟生育阶段互补,均能获得超亲的早熟材料。用获得的早熟材料与其他早熟亲本继续组配,或选早熟株系进行姐妹交,可以获得越来越早的早熟材料。2、矮秆育种,以矮×矮出现矮秆株系频率最高,易获得矮秆材料。矮×高或高×矮
Studying the genetic rules of the main traits of sorghum is closely related to improving the breeding effect. In several years of breeding work, the author studied the genetic breeding of sorghum in terms of precocity, dwarfness, quality, combining ability, resistance to abortion and infertility. The conclusions are as follows: 1. Using precocious parents, especially Is a premature inheritance of parents and other early maturing, maturing or late-maturing parent group, as long as the well-equipped, so that its premature birth stage of complementary, can get super pro-early material. With the early maturity of the material obtained with other early maturing parents to continue with the group, or selected early strains of sisters to pay, you can get earlier and earlier precocious material. 2, dwarf breeding, to dwarf × short dwarf strains appear the highest frequency, easy access to dwarf material. Short × high or high × short
