Abstract: This paper describes a partícip.tol)'maize breeding program that is a coll.boratíveproject between BiTS, Agricultural Universíty and the KRlBHCO Indo-British Rainfed Farming Project (Enst).At the beginning ofthe project, a base population was produced in Ihe rainy season of 1997 by making nine crosses between tbree yellow-endospermed flinl varieties (Suwan, Birsa Makka 1, and Chandan 3) and three white-endospermed flint varieties (GDRM 187, Shweta, .ndRudarpur local).The parental varielies were selected either because farmers in the project area had accepted Ihem or because they contributed complemental)' trails to the.population.The population has becn randomly m.ted for tive cycles by hiJI-planting seed derived from the original nino erosses .nddet.sseling 50% ofthe plants.After the initial random mating, eaeh eyele was planted from pale yellQw grains that sbould be heterozygous at the locos controlling endosperm color.Three composite varieties have been extracted from cyeles !bree and fOUT by nmdom mating of early-maturing plants (75 to 80 days) with eitheryellow or white grains.Preliminal)' resolts show !hat these populations are superior to local checks for multiple traits.lnterv.rietalhybrids were also made from farmer-preferred vaneties.Farmer-managed partí.ipatol)'researeh (FAMPAR) trials conducted in the rainy season.of1998 showed that farmers preferred the BM 1 x Suwan intervarietal hybrid lO the local varieties.Further evaluations ofhybrids in on-farro and station trials are being condocted.
