摘要：

长粒型籼粳杂交稻新组合浙优77是由浙江省农业科学院作物与核技术利用研究所、谷之雨(浙江湖州)农业科技有限公司、杭州种业集团合作选育的中熟三系籼粳杂交稻组合,以长粒粳型不育系浙杭K68A(浙75A)为母本、广亲和偏籼型恢复系浙恢F27为父本配组而成,2024年通过浙江省品种审定(浙审稻2024017)。浙优77具有产量高、米质优、转色好、适应性广等特点,适合在浙江省及周边稻区作单季晚稻种植。本文对浙优77的选育、品种特征特性和栽培技术做了简要介绍。

Abstract:

Zheyou 77, a new combination of long-grain indica and japonica hybrid rice, is a medium-maturity three-line indica and japonica hybrid rice co-bred by Crop and Nuclear Technology Utilization Institute of Zhejiang Academy of Agricultural Sciences, Guzhiyu (Huzhou, Zhejiang) Agricultural Technology Co., Ltd., and Hangzhou Seed Industry Group. It was composed of long-grain japonic-based sterile line Zhehang K68A (Zhe75A) as the maternal parent and a wide-compatibility partial indica restorer line Zhehui F27 as the male parent, and passed the Zhejiang provincial variety approval (Zhejiang-approved Rice 2024017) in 2024. Zheyou 77 has the characteristics of high yield, excellent rice quality, good color transformation and wide adaptability, which is suitable for single season late rice planting in Zhejiang Province and surrounding rice areas. In this paper, the breeding, variety characteristics and cultivation techniques of Zheyou 77 were briefly introduced.)
