油茶优良家系亚_1、亚_2、亚_6家系的选育,是在表型选择后进行测定而选出的。按试验要求重复布置试验,经连续4年测定,其经济性状和每平方米产果、产油量都超过全国优良家系标准,折算亩产油50kg以上,比参试家系平均亩产分别增产30.80％、34.7％和28.35％,具有显著的增产效果。产量、分枝数、分枝角度遗传力较高,家系内主要性状有较强的一致性,为选育提供了有价值的依据。
Breeding of excellent lines of Camellia oleifera subspecies, subfamilies, subfamilies, subfamilies, and subfamilies of the Camellia oleifera was selected after phenotypic selection. According to the test requirements repeated layout of the test, after 4 consecutive years of determination, the economic traits and yield per square meter of fruit, oil production exceeded the national standard of good families, converted per acre oil more than 50kg, than the average yield of the test families were increased 30.80 %, 34.7% and 28.35%, with significant yield increase. The heritability of yield, branch number and branching angle was higher, and the major traits in the pedigree had stronger consistency, which provided valuable basis for breeding.
