Three promising corn hybrids of KasetsartUniversity : Single cross Suwan 3701 ; three-way cross Suwan 3702 and three-way cross, KTX 3503, produced high yield in TAMNET trials from 7-13 countries of public and private sector, 2 international organizations (FAO & CIMMYT) , 141 entries tested at 69 locations in 6 years (1993-1998), (Chutkaew, 1994, 1994b, 1995; Chutkaew, et al, 2000), hence, inbred lines of these 3 hybrids (Ki31, Ki 32, Ki 42 and Ki 21) were provided to TAMNET member countries in 1995 and 1999 with an FAO Grant to KU.

4. Contributions of Inbred Lines of Promising Hybrids

With the promising performance to 2 KU hybrids, Suwan 3701 and Suwan3702, therefore, they were selected to be standard regional check varieties 1 and 2 in TAMNET trials in 1994 – 1998.

Their 3 promising corn hybrids and their parents are useful and applicable to farmers, corn breeders and young scientists.

5. Contribution for Regional Check

6. Training Corn personnel

Due to the KU contribution of both promising hybrids and inbred lines in No. (4) and (5) as mentions above, hence, the FAO requested KU to train 10 field corn and 15 baby corn scientists from 5 and 10 countries in 1994 and 1995, with the sponsor of FAO.
