摘要: 【目的】对在川北丘陵区直播种植的参试品种进行对比和综合评价,筛选出适合在此区域直播的高产水稻品种。【方法】以50个品种作为试验材料,对比油后直播条件下各参试品种的生育期与产量性状,研究其中对水稻产量产生影响的关键因素,对参试品种做出综合评价。【结果】相关性分析表明,油后直播条件下,生育期对产量性状均没有显著相关性,所有参试品种均能正常成熟。每穗实粒数和千粒重对产量显著正相关,选用大穗型品种是取得高产的一个关键。【结论】主成分分析表明,参试杂交稻中广8优589等品种产量表现较好,参试常规稻中粤禾丝苗等两个品种产量表现较好,这些品种适合在川北丘陵区进行油后直播。

Abstract: 【Objective】 To compare and comprehensively evaluate the tested varieties that were directly planted in the hilly area of northern Sichuan,and to select high-yield rice varieties suitable for direct seeding in this area.【Method】 With 50 varieties as test materials,the growth period and yield characteristics of each tested variety under the condition of direct seeding after harvesting rapeseed were compared the key factors affecting rice yield were studied,and a comprehensive evaluation of the tested varieties was made.【Result】 Correlation analysis showed that under the condition of direct seeding after harvesting rapeseed,the growth period had no significant correlation with yield traits,and all tested varieties could mature normally. The number of grains per panicle and 1 000-grain weight are significantly positively correlated with yield. The selection of large panicle varieties is a key to high yield.【Conclusion】 Principal component analysis showed that among the tested hybrid rice varieties,Guang 8 You 589 and other varieties performed better,and among the tested conventional rice varieties,four varieties including Yuehe silk seedlings performed better. These varieties are suitable for cultivation in the hilly areas of northern Sichuan after harvesting rapeseed.

Key words: rice, directly seeded after harvesting rapeseed, variety adaptability
