Abstract:

The inheritance o f a fiv e leaf let muta tion of so ybeans o riginally inheri ted from the w ildw as studied using cross a nalysi s. Six cro sses w ere made betw een "Five Leaf Bean" wi th the fiv eleaf let t rai t a nd o ther 6 lines of no rmal leav es. F2 plants o f 5 crosses produced majo r three a ndfiv e leaf let leav es and also some mino r four six a nd sev en multifoliola te leav es. There w ere tw okinds of seg reg atio n ra tios fo r major fiv e leaf let ( including other multifoliola te leav es) and t rifo liolate characters in the F2 prog eny plants. Fiv e crosses show ed a g oodness of fit to a 3∶ 1 ratioand one cro ss show ed a sa tisfacto ry 63∶ 1 ra tio. The cro ss a nalysi s indicated tha t besides theL f 1g ene co nt rolling fiv e lea flet s, there could be other tw o new ly found g enes g ov er ning this t rai t.These th ree g enes w ere independently g enetic, incompletely dominant and ef fect- duplica ted.
