果蔗间种菜用大豆的主要性状表现及其相关性分析

在果蔗间种条件下,考察13个菜用大豆的全生育期、株高、主茎节数、主茎分枝数、单株荚数、鲜百粒重、标准荚率、单粒荚率、瘪荚率和单株产量等性状表现,并进行相关性分析。结果表明:不同菜用大豆农艺性状存在差异,其中95C-10、桂鲜豆1号等5个品种单株产量较好;单株产量与主茎节数、单株荚数、标准荚、多粒荚呈显著正相关。因此,在果蔗间种菜用大豆时,要增加产量,应选主茎节数、单株荚数、标准荚和粒数较多的品种。

Agronomic Performance and Correlation Analysis of Vegetable Soybean when Interplanted with Chewing Cane

Under vegetable soybean/chewing cane interplanting conditions,the agronomic traits of vegetable soybean including growth duration,plant height,nodes of main stem,branches,pods per plant,fresh 100-seed weight,standard pod rate,1-seed pod rate,flat pod rate and yield per plant were determined and calculated.The agronomic traits varied greatly with varieties,and 5 varieties(lines)including 95C-10,Guixiandou No.1,Shanghaihongpi,Yin-01 vegetable soybean and Jiaoda 02-89 had higher seed yield.Seed yield per plant showed positive correlation with nodes of main stem,pods per plant and standard pods.Results suggest that in order to increase yield of vegetable soybean when interplanted with chewing cane,the varieties with more main stem nodes,pods per plant and seeds per plant should be selected.
