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.
