摘　　要：为筛选出适合赣北地区棉油连作轻简高效栽培的早熟高产油菜品种,并探明其产量形成特征,以13个油菜品种(系)为材料,对其早熟性、抗性、产量及产量构成等特征进行研究,并采用聚类分析、主成分分析等方法对参试品种进行综合评价。结果表明,这些品种的油菜籽产量为2361.4~2798.3kg/hm^(2),生育期为198~205天;产量与每株角果数、日均产量成极显著正相关;高产类品种的产量、收获密度、每株角果数及日均产量均显著大于低产类品种,千粒重显著低于低产类;高产类品种主要表现为具有较高的收获密度、每株角果数和每角粒数,且早熟性好。通过综合评价筛选出中油899、zy832两个高产且性状优良的品种,适合赣北地区种植。In order to screen out high-yield rape varieties suitable for light,simple and efficient cultivation of cotton-rape continuous cropping in northern Jiangxi,and explore their yield formation characteristics.13 rape varieties(lines)were used as materials to study their characteristics such as early maturity,resistance,yield and yield composition,and comprehensively evaluate each rape variety by means of cluster analysis and principal component analysis.The results showed that the rapeseed yield of these varieties ranged from 2361.4 to 2798.3 kg/hm^(2),and the growth period ranged from 198 to 205 days;the yield was positively correlated with the number of pods per plant and daily average yield;the yield,harvest density,number of pods per plant and daily average yield of high-yield were significantly higher than those of low-yield variety,and the 1000 grain weight of high-yield was significantly lower than that of low-yield.High yield varieties are mainly reflected in their high harvest density,number of pods per plant and number of grains per pod and good early maturity.Two high-yielding and excellent varieties of Zy899 and zy832 were selected through comprehensive evaluation,which are suitable for planting in northern Jiangxi.
