绿豆主要数量性状与杂交后代的选择

Selection among Main Quantitative Characters and Hybridized Progeneies in Green Gram

采用ＳＷｒｉｇｈｔ提出的通径分析方法，对绿豆１１个数量性状与产量之间的关系进行了研究。提出了在杂交后代选育绿豆高产品种的策略，即选择荚长９ｃｍ左右、百粒重＞５ｇ、单株荚数适中（２０个左右）、主茎节数多（＞１０个）、植株矮（８０ｃｍ左右）。

The relationship among 11 quantitative characters and yield in green gram was studied by adopting path analysis proposed by S Wright. The breeding tactics were put forward as that in developing high yield varieties in green gram,the single plants with shorter pods(about 9cm),higher 100-grains weight(more than 5g),suitable pods No.(about 20),more nods No.in main stem(more than 10),dwarfer plant height(80cm or so),and proper grain No.(12 grains or so per pod)should be selected.
