Abstract:
Transformation ability characteristics of dry matter were one of important high-yielding traits.Two hundred and twelve soybean lines belonging to 7 maturity group in 2005 and 191 lines belonging to 6 maturity group in 2007 were adopted to investigate transformation traits of harvest weight(HW)，seed weight(SW)，apparent harvest index(AHI)，stem weight(SW)，seed-stem ratio(SSR)and actual harvest index(AHI).The data of transformation ability were accurate in 2005(normal year)，but not accurate in 2007(arid year).Average transformation ability of four groups from middle-ate maturing to early maturing was increased in proper order in 2005.The inhibition of transformation ability led to the decrease of seed yield and the disorder of transformation ability among different maturing groups in 2007.In 2005，variation coefficient(CV)of HW，SW and AHI were smaller，while variation coefficient of SW was relatively bigger，and opposite trend was presented in 2007.Correlation between maturity and transformation ability varied greatly among different maturing group soybeans.CV between SW and SSR varied greatly among different maturing groups and less than fifty percent of them reached significant level，while CV between AHI and SSR was significant.Selection for AHI using SSR or AHI was efficient.Obvious difference in SSR existed in same maturing group lines.Soybeans with high transformation ability could be obtained in different maturing period materials and germplasms with high transformation ability had been screened.
