Abstract:

Fascia ted cha racter of fasciated soy bean f rom U. S. w as co nt rolled by a recessiv emajo r g ene and few mino r modi fing g enes. Ra tio of no- fasciated plant a nd fasciatedplant w as 5∶ 1 in F2 of crosses betw een common soy bean variety a nd fascia ted so ybeanf rom America. Al l plants in F3 lines from F2 fasciated plant w ere fasciated. In homo zygous dominant ( FF) progenies f rom F2 no rmal pla nt s o r plants that plant high t over parentsthe homozyg ous FF g ene pai r deriv ed no fasciated plants, and in mo st of the heterozygo us ( Ff ) progenies f rom F2 , ratio betw een non - fasciated plants and fasciatedplants did no t fit 3∶ 1, fasciated plant ratio w as clearly low er.Fascia ted so ybean pla nt s o f China w ere divided into 6 g ro ups depend upon thei r fasciated deg ree. 4th a nd 5th g roup plants of less fasciated deg ree and pa rtial fasciation had52% , 3th g ro up plants of middle deg ree fascia tion 20% , 1th a nd 2th gro up plants ofhigher deg ree ot fascia tio n 15% , and o f that of norma l type plants 15% . Thi rd and 4thg roup plant had best seed yield per plant. Fascia ted character can produce easily underthe planting co ndatio n of ferti le soi l. F1 pla nt s of cro sses betw een fascia ted soybea n ofChina and common so ybean v arieties w ere normal ty pe. 40- 90% lines o f F2 o r F3 g enerationof di fferent crosses giv e rise fasciated plants a nd the o ccuring f requency in the linesw as 3- 12% . No. of fasciated plant in F3 lines of most fasciated plant s was more thanthose in F2 lines, being 13- 70% and 6. 6- 23. 0% pla nt s respectivelly. Fix atio n degreeo f fasciated character o f F3 lines w as clearly larg er tha n that of F2 lines. Selectio n ofmore fix ed fascia tion line to compare wi th fasciated soy bean o f China w as probable. Fasciated cha racterc of China w as cont ro lled by a recessiv e majo r g ene and some microeffectmino r g enes.
