摘要:

经对来自10个省(区)184个种质资源号及275个地方品种、单亲家系、双亲家系和无性系系统的研究分析与选育,基本摸清油桐主要性状的遗传参数,并得出油桐为“常异花授粉树种”的结论;制定了油桐育种程序和途径,选育出3个优良家系、4个优良无性系、1个“矮早丰”优良品种和1个优良杂交组合;收集了来自全国油桐产区的种质资源451个;生产并推广良种13×104kg。应用这些良种的遗传增益(△G)在34.0%-59.8%。这一研究为油桐生产和遗传改良提供了理论依据,并提供了部分育种和生产资料。

Abstract:

By systematic analysis, selection and breeding of 184 germ plasm resources and 275 local varieties, half-sib families, full-sib families and clones from ten provinces or districts, the hereditary parameters of main characters of Aleurites fordii were found out. The conclusion that Aleurites fordii is a tree species of normal cross pollination has been drawn. The progamme and way for Aleurites fordii breeding have been laid. Three fine families, four fine clones, one 'dwarf, early and high yield' fine variety and one fine hybrid combination have been selected. 451 germ plasm resources were collected from the producing area of Aleurites fordii throughout the whole country. 13×104kg elite seeds were produced and spread, with which the hereditary gain (△G) was 34.0%-59.8%. The theoretical basis was provided for production and hereditary improvment of Aleurites fordii in this study, part of data were provided for seed selection and production.
