Genetic Variation of Plus Tree Open-pollinated Progenies in Quercus variabilis
摘要
Abstract
The variations of the leaves and growth traits as well as peroxidase of 4-year-old plus tree open-pollinated progenies from six Quercus variabilis populations were investigated.The results showed that there were significant differences in seedling height, leaf length, leaf width, petiole length, and leaf area among different populations, and in seedling height, leaf length among different families.The peroxidase isozyme of Q.variabilis consisted of two locis.The mean of alleles was2.479 and the expected heterozygosity was 0.282.Within the population, genetic variations accounted for 54％ of the total genetic variations.With seedling height as the main character, 10 superior families were selected preliminarily from 57 tested families.Their height growths increased by 31.7％～84.0％ than the overall population average.关键词
