26个花生品种果柄强度研究

Analysis on Peg Strength of 26 Peanut Varieties

果柄强度是影响花生机械化生产的重要农艺性状。本研究对分段式收获的26个花生品种的果柄强度进行了测定。结果表明,26个花生品种经起拔、大田晾晒3日后的果柄强度普遍偏低;大花生、小花生品种的果柄强度没有显著差异;其中13个品种的果柄强度随荚果成熟度变化而有显著变化,而另外13个品种并没有显著变化。本研究为培育适合机械化收获的花生新品种奠定理论基础。

Peg strength is one of the important agronomic traits in peanut mechanized production. The peg strength of 26 peanut varieties were detected and analyzed after harvest in this paper. The results showed that the peg strength of all the varieties were generally lower after pulled up and naturally dried in field for three days. There were no significant differences between large and small podded varieties in peg strength. In13 varieties,the peg strength changed significantly with the pod maturity,while that of the others was not.This study would provide a theoretical basis for breeding new peanut varieties suitable for mechanical harvest.
