芝麻三系杂交品种皖芝11号株型特征及产量表现研究

Plant Type Characteristics and Yield Performance of a Three-line Hybrid Sesame Wanzhi 11

为明确芝麻三系杂交品种皖芝11号的株型特征及产量表现,对芝麻三系杂交品种皖芝11号与常规栽培品种进行了比较试验。结果表明,在盛花期,杂交品种皖芝11号的株高、主茎直径、叶长、叶宽、叶面积指数等性状较亲本皖芝2号和对照品种豫芝4号要高,表明其具有较强的光合作用能力;皖芝11号盛花期干物质积累量分别较亲本材料皖芝2号和对照品种豫芝4号高24.45%和34.45%,且其具有最高的经济系数(0.212);杂交品种皖芝11号的每蒴粒数、千粒重、单株产量等产量构成因子表现出超亲优势和超标优势,皖芝11号产量为1 430.00 kg/hm^2,显著高于对照品种豫芝4号,适宜推广种植。

In order to clarify the plant type characteristics and yield performance of a three-line hybrid sesame variety Wanzhi 11,a comparative test of the three-line hybrid sesame variety Wanzhi 11 and conventional cultivar was carried out.The results showed that,compared with the parent Wanzhi 2 and the control variety Yuzhi 4,the plant height,diameter of main stem,leaf length,leaf width,leaf area index of the hybrid variety Wanzhi 11 increased at full-bloom stage,indicating that it had strong photosynthetic capacity.The dry matter accumulation of Wanzhi 11 was 24.45%and 34.45%higher than that of the parent Wanzhi 2 and the control variety Yuzhi 4 at full-bloom stage,respectively.In addition,Wanzhi 11 had the highest economic coefficient(0.212).Transgressive heterosis and superstandard heterosis were observed in the yield component factors of the hybrid variety Wanzhi 11,such as number of seeds per capsule,1000 seed weight,yield per plant,etc.The yield of Wanzhi 11 was 1430.00 kg/hm^2,which was significantly higher than that of the control variety Yuzhi 4,and was suitable to plant widely.
