测定表明,茶叶产量是由幼嫩新梢所组成,其生长量是有限的;优质茶叶又必须采摘嫩度较高的幼小的新梢;此乃茶叶产量受到限制的主要原因。世界上饮用的茶叶均采自多年生灌木型茶树(Camellia Sinens1s),目前所采用的无性系品种对茶叶品质均有提高,但其中大部份都是未经筛选或筛选很差的品种,因而在茶园中可以看到高度的多态现象。这种表现型的变异可能是由于它们的遗传起源不同和物种自然异型杂交所致,在田间虽可识别出各种不同的形态学特征,但目前对它们的遗传率或哪些特征与高产相关尚不清楚。本文对选育高产植株作种质材料的重要性进行了讨论。
Determination shows that the output of tea is composed of young shoots, its growth is limited; high-quality tea must pick young shoots with higher tenderness; this is the main reason for the limited production of tea. The world’s drinking tea are collected from the perennial shrub tea (Camellia Sinens1s), the clones currently used to improve the quality of tea, but most of them are not screened or poor screening of varieties in the The tea plantation can see a high degree of polymorphism. This phenotypic variation may be due to their genetic origins and natural heterozygosis of the species, although a variety of morphological traits may be identified in the field, but their heritability or characteristics are currently associated with high yield Not clear. This article discusses the importance of breeding high-yielding plants as germplasm material.
