贵州芝麻不同地方种质资源产量

通过对贵州芝麻不同种质资源的产量与相关性状分析。结果表明：各个品种产量在35.72kg/亩—146.94kg/亩之间。其中产量最高的品种是P41(SI17TR-2),为146.94kg/亩；其次是P28(SI16BZ-14),为143.95kg/亩；最低的品种是P8((SI16BZ-7),为35.72kg/亩。各个个性状对产量影响的大小顺序为：单株果数>千粒重>主轴果数>主轴结果长度>生育期>单果粒数>生育期。株高、单株果数、主轴果数、单果粒数、千粒重的直接通径系数均为正值；而生育期、主轴结果长度的直接通径系数均为负值。综合考虑,P41(SI17TR-2)、 P28(SI16BZ-14)两个品种为高产品种,适宜在遵义地区大面积推广种植。

Analysis on Yield And Related traits of germplasm resources in different places of Sesame in Guizhou

the yield and relative characters of different germplasm resources in Guizhou sesame were analyzed. The results showed that the yield of each variety was between 35.72 kg/mu and 146.94 kg/mu. The highest yield species is P41(SI 17TR-2), which is 146.94 kg/mu; Followed by P28(SI 16BZ-14), 143.95 kg/mu; The lowest variety is P8((SI 16BZ-7), 35.72 kg/mu. The order of the effects of individual traits on yield is: individual fruit number GT; Thousands of grains GT; Main axis fruit number GT; Main axis result length GT; Fertility period GT; Single fruit number GT; Fertility period. The direct diameter coefficients of plant height, single fruit number, main axis fruit number, single fruit number, and thousand grain weight were all positive. However, the direct diameter coefficient of the growth period and the length of the main axis were negative. Taken together, the P41(SI 17TR-2) and P28(SI 16BZ-14) varieties are high-yield varieties and are suitable for large-scale cultivation in Zunyi.
