以高EGCG茶树新品系为主要杂交亲本,分析其杂交F1代儿茶素类的遗传表型。结果表明:杂交F1代的EGC、EC、EGCG、ECG、酯型儿茶素类、简单儿茶素类、TC(儿茶素总量)、酯型儿茶素类/TC、简单儿茶素类/TC、EGCG/咖啡碱、EGCG/TC、儿茶素(类)品质指数等指标,不同株系差异很大;不同杂交组合存在显著差异,Kruskal Wallis检验和稳健检验均达显著性水平;不同杂交组合的分离存在极显著性差异,方差齐性检验表明达到极显著性水平。不同杂交组合F1代TC的分布因亲本的遗传力而定;不同杂交组合F1代高EGCG单株、高酯型儿茶素类单株和高儿茶素(类)品质指数单株的分布也因亲本的遗传力而定。
The high EGCG tea tree new lines as the main hybrid parents, analysis of their F1 hybrid generation of catechins genetic phenotype. The results showed that EGC, EC, EGCG, ECG, ester type catechins, simple catechins, TC (total catechins), ester type catechins / TC, simple catechins TCB, EGCG / caffeine, EGCG / TC, catechin (quality index) and other indicators, different strains vary greatly; different cross combinations there are significant differences, Kruskal Wallis test and robust test were significant levels; different There was a significant difference in the segregation of hybrid combinations, and homogeneity of variance test showed that it reached a very significant level. The distribution of TC in F1 hybrids of different crosses was determined by the heritability of the parents. The distribution of high EGCG single plants, high-ester catechins and high catechins in different hybrid F1 hybrids Due to the heritability of the parents.
