一、茶树抗寒育种研究动态随着人民生活水平的提高,茶叶已成为多数人日常生活中的饮料,茶叶消费量日渐增多。种茶的面积日渐扩大,出现北方茶区迫切要求抗寒性强的茶树品种,因而对茶树育种工作者提出一个重要的问题——选育抗寒性强的优良品种。从六十年代以来,国内外不少茶树育种工作者根据茶树不同的遗传特性,选育抗寒茶树品种。日本乌屋尾忠之(1977)曾研究抗寒茶树的基因型和表现型,认为茶树叶子抗寒性是由多基因支配的,杂交后代呈常
First, the cold tea breeding research trends With the improvement of people’s living standards, tea has become the majority of people’s daily life beverages, tea consumption is increasing. The growing area of tea has led to the urgent need of the tea plantations in the northern tea plant that have strong cold hardiness. Therefore, tea plantation workers have raised an important issue - breeding excellent cold-resistant varieties. Since the 1960s, many tea tree breeders at home and abroad have selected different varieties of cold-resistant tea trees according to the different genetic characteristics of tea trees. Japan Wuyao Tatsumi (1977) had studied the genotype and phenotype of cold-resistant tea tree, that tea cold hardiness is dominated by polygenes, hybrid progenies were often
