Abstract:

Acco rding to AV RDC a nnual Prog ress Repor ts, We review ed the adv ances ofsoybean g ermplasm researches a t AV RDC. AV RDC had int roduced 13, 618 so ybeang ermpla sm accessio ns f rom more than 50 count ries or areas during 1973- 1995. All thesoybean accessio ns are co nserv ed in lo ng- term a nd medium- term sto rag e rooms. Anew cent rali zed g ermplasm introductio n sy stem was setabli shed in 1986 and has beenused since that time. All the col lectio ns have their ow n passpo rt data w hich are availableto all scientist s. In order to understand the nature o f di fficulty fo r sto rag e of so ybean seeds, mo re researches w ere co nducted o n storage tech niques, storag e co ndi tio ns, seedlo ng evi ty , cha ng es o f seed chemical substa nces in the period o f sto rag e. Almost all thecollections w ere ev aluated o n the trait s o f high yielding , early maturi ty , insensi tivi ty tophotoperiod, resistance to diseases o r insect pest s etc. Some accessio ns w erecha racteri zed based on IBPGR’s descripto rs fo r so ybean. The researchers o n so ybeanbreeding , patholo gy , entomo log y, seed scicence screened a number o f g eno ty pes w ithdesi rable t rai ts. By using these desi rable germplasm, scienti st s of AV RDC hav edev elo ped a lo t of AGS lines o r GC lines, which are hig h yielding wi th resi stance o rtolerance to soybea n di seases, o r wi th ea rly maturity, o r wi th insensi tiv ity tophotoperids and adapt to pla nt in t ro pical a nd sub - t ropical areas. The so ybeanaccessions a nd breeding lines collected at AV RDC hav e been dist ributed to the na tionalinstitutions and priv ate persons w ho asked for them. The wide di stribution o f AV RDCsoybean col lectio ns has enlarg ed their utilization in t ropical and subt ro pical co unt ries.
