通过对7个旱地芸豆品种(系)的5个主要性状与籽粒产量间进行相关、通径及决定子数分析结果表明,单株粒数、单株荚数对籽粒产量效应值均较大,而百粒重表现为较小的负值。故在旱地品种选育上应注重多荚多粒型,而不能片面追求大粒型,生产上旱地栽培,应选择百粒重在30g左右,单株荚多粒多的串蔓型品种。 Through the correlation analysis of five main characters and grain yield of 7 dry kidney bean varieties (lines), the results of path and decision number analysis showed that grain yield per plant and pods per plant were all larger, The 100-pound weight showed a smaller negative value. Therefore, the selection of dry land varieties should pay attention to multi-pod multi-grain type, rather than one-sided pursuit of large grain type, the production of dry land cultivation, should choose one hundred grain weight in about 30g, single grain pods and more string type varieties.
