摘　　要：为探究不同类型向日葵品种产量及其相关性状的差异性,试验选取9个食用型向日葵品种和4个油用型向日葵品种,进行了产量及其构成因素、干物质、叶片SPAD值等方面的研究。结果表明:食用向日葵以SH363产量为最高,达到了5.15 t/hm2,较平均产量高出28.43%;油用向日葵以TP261产量为最高,达到了4.34 t/hm2,较平均产量高出6.03%;产量及其相关性状相关性分析表明:单盘粒重对产量的影响最大,可以作为高产品种评价的参考指标之一,而单盘粒数与籽粒长度可作为衡量皮壳率的重要指标之一。该研究为筛选不同类型高产向日葵品种指标的确定提供了理论依据。To study the differences in yield and characters of different sunflower varieties,9 edible sunflower and 4 oil sunflower varieties were selected.The yield,yield components,dry matter accumulation and SPAD values were studied.The results showed that the yield of SH363 was the highest of the edible sunflowers,up to 5.15 t/hm2,which was 28.43%higher than the average yield;the yield of TP261 was the highest of the oil sunflowers,up to 4.34 t/hm2,which was 6.03%higher than the average yield.The correlation analysis of yield and its related characters showed that the single disk weight had the greatest impact on the yield,and can be used as one of the reference indexes for the evaluation of high yield varieties.The single disk number and the length of grain can be used as two of the important indexes to measure the shell rate.This study provides a theoretical basis for the determination of the indexes for screening different types of high-yield sunflower varieties.
