吉林省高梁育种工作者经过20多年的杂优育种工作培育和引进上百个不育系和恢复系亲本材料,通过筛选、加工,培育出一大批优良的亲本。这些优良材料基本上可代表目前该省高梁亲本的种质资源。本文采用随机抽取亲本按不完全双列杂交设计估计了该省高粱亲本总体的单株产量等数量性状的基本遗传参数。为其在杂优育种中合理利用及进一步改良这些材料提供一定的理论依据。 After more than 20 years of hybrid breeding, sorghum breeding workers in Jilin Province have cultivated and introduced hundreds of male sterile lines and restorer lines, and screened and processed a large number of excellent parents. These fine materials can basically represent the germplasm resources of sorghum parents in the province at present. In this paper, randomly selected parents were used to estimate the basic genetic parameters of quantitative traits per plant such as single plant yield in the whole province. Provide some theoretical basis for its rational utilization in heterosis breeding and further improvement of these materials.
