强优势杂交稻新组合在云南的产量潜力及适应性探究
|
摘要
本研究以云南省农业科学院粮食作物研究所选育出的3个杂交籼稻新组合HWHR1、HWHR2、HWHR3为参试品种,绵优725为对照,在云南省水富县、华坪县、芒市3个不同籼稻种植区开展品比试验及生产试验,对主要经济性状及产量表现进行比较分析。结果表明,3个参试品种中,HWHR2综合表现良好,增产点次率大于65%,小区品比试验平均产量12 467.0 kg/hm2,比对照增产3.3%,生产试验产量13 501.5 kg/hm2,比对照增产9.2%,在云南不同籼稻区具有较好产量潜力和适应性。高产广适杂交稻新品种的选育对保障粮食安全具有重要意义,进行生产潜力及适应性研究有助于新品种的推广应用。
In this study, three new combinations of indica hybrid rice(HWHR1, HWHR2 and HWHR3 bred and selected by Institute of Food Crops of Yunnan Academy of Agricultural Sciences)(test materials) and Mianyou 725(control) were used for variety comparison trials and production trials at three different indica rice planting areas(Shuifu, Huaping, and Mangshi Counties) in Yunnan Province. The main economic traits and yield performance were compared and analyzed. The results showed that the comprehensive performance of HWHR2 in three cultivars was good with the increase yield over 65%. The average yield of variety comparison trial was 12 467.0 kg/hm2, which was3.3% higher than that of the control. The yield of production trial was 13 501.5 kg/hm2, which was 9.2% higher than that of the control, indicating better yield potential and adaptability in different indica rice areas in Yunnan Province.The breeding of new hybrid rice varieties with high yield and wide adaptability was of great significance to ensure food security. The study of production potential and adaptability might be helpful to the popularization and application of new varieties.
