茶树单株选择
individual selection of tea plant
茶树单株选择(individual seleetion oftea Plant)茶树选择育种法之一。又称茶树系统选择或茶树个体选择,即从现有茶树群体品种或育种材料中,根据育种目标.选出一定数量的优良个体,分别进行扦插繁殖,然后通过品比试验,从而育成新的茶树品种的方法。单株选择方法简单,效果显著,是最常用的茶树育种方法。国内外许多茶树新品种,多数都是采用此法育成的。OQQ皿命。户。喊只 ,协.,、护口,才,尸、 I矛尚画┌────┐│乡礴黔 │└────┘ ┌──┐ │‘奋│ │命 │ │Q │ │石户│ │Q │ │戈奋│ └──┘ 尹 ︸碗.︸‘l咬峨心嵘叹< r..﹄L‘ 护l由回回图┌─────┐│户.产产, ││严产严 ││严产,尸 ││严严严 ││尹.加尹, ││声.产,产.│└─────┘┌──────┐│l。尸尸 ││声,产,产,││产,严声, ││声,严户 ││户严尸 ││产,尸尸 │└──────┘ 茶树单株选择图式 由上至下:1.第l年从原始群体中选择优良植株2.第2~3年分株初步繁值,并继.续鉴定入选单株3.第3~10年比较试脸(右第1行为对照品种),同时进行区城性试脸4.第10年以后良种繁殖推广 (刘祖生)
