选用16份绿豆品种为试验材料,研究产量与主要农艺性状之间的相关性。结果表明,产量与单株荚数和单荚粒数呈极显著正相关,而与生育期、株高和荚长呈极显著或显著负相关。偏相关分析表明,产量与株高、单株荚数和百粒重呈显著或极显著相关。通径分析显示,主茎节数、百粒重和单株荚数对产量的直接效应最大。高产育种选择中,应考虑到绿豆农艺性状之间的相互关系,实现各性状之间最佳关系,达到产量最大化目标。
16 mung bean varieties were selected as test materials to study the correlation between yield and main agronomic traits. The results showed that there was a significant and significant positive correlation between yield and pod number per plant and grain number per pod and extremely significant or significant negative correlation with growth stage, plant height and pod length. Partial correlation analysis showed that there was a significant or significant correlation between yield and plant height, pods per plant and 100-kernel weight. Path analysis showed that the direct effect of the main stem number, 100-grain weight and pods per plant on the yield was the largest. In the selection of high-yielding breeding, the relationship between the agronomic characters of mung bean should be taken into consideration to achieve the best relationship among the traits and achieve the goal of maximizing the yield.
