贵辐糯系我所采用钴六十伽吗射线处理双城糯干种子,诱发突变体,经多代选育而成的粳型糯稻新品种,具有产量高、品质优、抗逆性强、适应性广和容易脱粒等优点。1989年经贵州省作物品种审定委员会审定为推广品种。在省内已有70多个县(市)、省外有30多县(市)引种栽培和推广利用。 一、选育过程 1980年,采用~(60)Co一у射线3万伦琴照射双城糯干种子,M_1代丛栽混收,M_2代单株栽植,收获前,逐株观察选择,从中选得植株较双城糯稍高、熟期略早和较易脱粒的突变体,从M_3代起繁育成株系,经连续签选、于1984年M_5代定型,1987年定名为“贵辐糯”
Gui Fung Glutinous Rice is a new Japonica type glutinous rice variety which is made of multi-generational breeding of glutinous dry seeds of Shuangcheng using cobalt sixty gamma rays. It has many advantages such as high yield, good quality, strong resistance, Wide adaptability and easy threshing and so on. In 1989 by the Guizhou Provincial Crop Variety Approval Committee for the promotion of varieties. In the province has more than 70 counties (cities), outside the province more than 30 counties (cities) to introduce cultivation and promotion. First, the breeding process In 1980, the use of ~ (60) Co ray ray 30 000 Ruanqin irradiation Twins glutinous dry seeds, M_1 Cong planted mixed, M_2 on behalf of single plant planting, before harvest, the observation and selection of each strain, from the election The plants were slightly higher than the twins glutinous rice, mature slightly older and more easily threshed mutants from the generation of M_3 bred into lines, after a series of sign-off, in 1984 M_5 behalf of stereotypes, 1987, "
