水稻新品种湘优616选育、品种特性和高产栽培技术

湘优616是湖南省永州市农业科学研究所利用自选恢复系R616作父本与湖南省杂交水稻研究中心选育的湘丰70A作母本配制而成的一个高产、稳产、抗性好、出米率高的三系早籼杂交组合。该组合2011和2012年连续2年参加湖南省早稻迟熟组区试验,2年平均产量达7725.15 kg/hm2,比对照增产4.69%;该组合表现出生育期适中、分蘖力强、穗大粒多、产量高、米质优等特点;同时,介绍了该组合的制种关键技术、品种特性和高产栽培技术要点。...

Xiangyou 616 is a three -line early -season indiea hybrid rice combination with high yield, stable yield, strong resistance and high milled rice rate, which was bred from the hybridization between restoring line R616 （ male parent） and Xiangfeng 70A （female parent） by Yongzhou Municipal Institute of Agricultural Sciences in Hunan Province. In the regional tests for late - maturing early rice varieties of Hunan province during 2011 -2012, the average yield of Xiangyou 616 reached 7725.15 kg/hm2 , being 4.69% more than that of the control; Xiangyou 616 was characterized by moderate growth and developmental duration, strong tillering ability, large spike and more grains, high grain yield, good rice quality, and so on. Meanwhile, the seed -production key techniques, varietal characteristics, and high - yielding culture techniques of this combination were introduced.
