Abstract:
Prog enies of crosses amo ng three obv iously di fferent ty pes o f so ybeans w ere madefo r selection by fo llowing methods: pedig ree selectio n, o ptimum selectio n wi thin a cro ssand random selection wi th simila r purposes in Haina n Island. The o bjectiv e o f thi s studyw as to compare the effectiv eness o f th ree selectio n methods, and to find an appropria temethod fo r soybea n breeding co rresponding to the speci fic type o f cross in Haina n Island.The ex perimental resul ts pointed out that there w ere no sig nificant di fferences ong enetic adva nce in ma turi ty, plant height , pods, seeds and yield per pla nt. How ev er,there w ere larg er dif ferences in si ze of 100- seed w eig ht , lo dging , pod- spli tting indexamong the ma terials selected by three methods. In mo st cases, ma terials selected byprdig ree method a nd optimum selection f rom crosses containing wild o f semi- w ild soybean paren show ed faster genetic adv ance than that by random selection method.Based on the result s o f the study, the optimum selection method wi thin a cross w assug gested the interspeci ffic crossing of so ybeans in Hainan Island.
