金蕾一号晚熟黄花菜品种选育初报

Preliminary Breeding of Late-Maturing Day-lily Jinlei No.1

为了使庆阳黄花菜采收初期错开夏收农忙关键时节,本研究采用系统选育方法,选育出晚熟黄花菜新品种金蕾一号。结果显示,该品种比马莲黄花、线黄花晚熟10 d以上、采收期延长4 d以上,产量分别提高3.41%和5.16%,且农艺性状优良、抗逆性强。新品种可以有效解决庆阳黄花菜产区主栽品种采收初期与夏收农忙季节重叠,种植户因抢收夏粮,无力采收加工黄花菜,造成大量损失的问题。

Abs tract In order to stagger the harvesting time of day-lily and critical busy farming time on summer in the producing region of Qingyang areas, a new variety of late-maturing‘day-lily Jinlei No.1＇was bred systematically.The new variety has good agronomic traits and strong resistance, ripening time of which is more than 10 days late,the harvest time postponed for 5 days and the yield increased by 3.4% and 5.2%, respectively, compared with Malianday-lily and Xian day-lily. This avoids heavy losses due to farmers too busy in harvesting summer grain to harvest day-lily timely.
