摘要:

为筛选适宜浙江地区种植的双季稻新品种,本研究以浙江省诸暨市为例,于2024年开展新品种展示试验,以中早39和甬优1540为对照品种,对20个早稻和14个连作晚稻品种的主要农艺性状进行综合评价。结果表明,早稻品种舜达135的667 m2产量最高,为679.1 kg,较对照增产18.2%;晚稻品种嘉丰优2号的667 m2产量达732.2 kg,较对照增产15.3%。甬优59等品种在产量与抗倒性方面表现均衡。本研究通过产量和抗性综合分析,筛选出综合性状优良的早稻品种和连作晚稻品种,为浙北地区双季稻品种更新提供了科学依据。

Abstract:

To screen for new double-cropping rice varieties suitable for cultivation in Zhejiang,this study conducted a demonstration trial of new varieties in Zhuji City,Zhejiang Province,in 2024. Using Zhongzao39 and Yongyou1540 as control varieties,we comprehensively evaluated the major agronomic traits of 20 early rice and 14 continuous-cropping late rice varieties. The results showed that the early rice variety Shunda135 had the highest yield(679.1 kg per 667 m2),an increase of 18.2% compared with the control. The yield of late rice variety Jiafengyou2 reached 732.2 kg per 667 m2,an increase of 15.3 % compared with the control. Varieties such as Yongyou59 exhibited a balanced performance in terms of yield and lodging resistance. This study screened early rice varieties and continuous cropping late rice varieties with excellent comprehensive traits through comprehensive analysis of yield and resistance,providing a scientific basis for the renewal of double-cropping rice varieties in northern Zhejiang.
