Autumn Maize Varieties Screening Test and Correlation Analysis of Main Quantitative Traits in Fujian

摘要: 引进不同生态类型的品种进行秋季多年和多点试验, 并对产量及主要数量性状进行相关和通径分析, 探讨选育福建省秋玉米高产品种的方法。结果表明, 登海3622、德瑞29和苏试50103丰产性、稳产性和抗逆性好, 适宜福建作秋玉米种植;在秋玉米高产品种的育种策略上, 要注重南方锈病的抗性选育, 并注重穗长、百粒重的增加, 生育期应适中, 不宜太长。

Abstract: In this study, in order to select the suitable autumn planting maize varieties in Fujian, we introduced a lots varieties of maize from different ecological types, and tested them through years and multi-point testing in the autumn.Moreover, we carried out the correlation and path analysis of the main quantitative characteristics and yield on maize, in order to study the method of breeding high yield of autumn planting maize.The results showed that denghai3622, derui29and sushi50103had high and stable yield and good resistance adapted to autumn planted in Fujian.In the strategy of breeding high yield autumn planting maize, it′s important to select the varieties of resistant to south-rust disease, and take into account of ear length and hundred-grain weight increase. Furthoremore, the growth season for maize should moderate, but the long growth season is not inadvisable.
