Abstract

Abstract: Chunyou 84 was developed by China National Rice Research Institute and Zhejiang Nongke Seed Industry CO., Ltd. Chunyou 84 belongs to three-line hybrid japonica rice, and the female parent of this combination is Chunjiang 16A, the male parent of this combination is C84. Chunyou 84 performed well in the field, showing stronger stem, higher lodging resistance, bigger panicles, higher spikelet fertility and good grain quality. Chunyou 84 was released by Zhejiang provincial crop variety appraisal committee in 2013 . The combination is suitable for cultivation in Zhejiang province as single cropping late rice. The growth characteristics and key cultivation techniques for high yield of Chunyou 84 were concluded in this study.

Key words: hybrid japonica rice, chunyou 84, characteristics, high yield cultivation techniques

摘要： 春优84是中国水稻研究所和浙江农科种业有限公司合作，用春江16A与C84组配而成的三系杂交粳稻新组合。该组合表现出茎秆粗壮、耐肥抗倒、穗大粒多、丰产性好，米质较优等特点。2013年通过浙江省农作物品种审定委员会审定，适宜在浙江省作单季晚稻种植。本文总结了该组合的生育特性及高产栽培技术要点。
