江麦23丰产稳产性及产量构成因素分析
Analysis of High Yield,Stable Yield and Yield Components of Wheat Variety Jiangmai 23
【摘要】 根据江苏省2013—2017年淮北小麦品种试验4年汇总数据,分析了江麦23的丰产性、稳产性、适应性及产量构成要素。结果表明,江麦23是一个具有良好的丰产性(较对照淮麦20增产3.13%~5.79%)、稳产性(3年高稳系数HSC高于对照)、适应能力较强(4年适应度高于对照)的小麦新品种,适宜在淮北地区推广种植。此外,产量构成三要素分析表明千粒重对产量的直接作用最大,其次是穗数,穗粒数对产量的直接作用最小。因此,在稳定穗粒数的前提下,提高千粒重和增加有效穗数是提高江麦23产量的关键。
【Abstract】 The high yield, stable yield, adaptability and yield components of Jiangmai 23 were analyzed based on the 4-year data of wheat test in Huaibei area of Jiangsu Province from 2013 to 2017. The results showed that Jiangmai 23 was a new wheat variety with high yield(3.13%-5.79% higher than that of the check variety Huaimai 20), stable yield(the high stability coefficient was higher than that of Huaimai 20 in 3 years) and good adaptability(higher adaptability than that of Huaimai 20 in 4 years). Jiangmai 23 was suitable for planting in Huaibei area of Jiangsu Province. In addition, the analysis of three yield factors showed that 1 000-grain weight had the most direct effects on yield, followed by panicle number, and grain number per panicle had the least direct effects on yield. These results indicated that under the premise of stable grain number per panicle, increasing the 1 000-grain weight and the effective panicles were promising to increase the yield of Jiangmai 23.
