The development of early mature high yielding faba bean (Vicia faba L.) cultivars is one of the most important activities of breeding program in Egypt. Early mature cultivars are needed to increase faba bean area through planting faba bean prior to cotton instead of berseem clover. The new cultivar Sakha 1 (x 957) was released in 2001 for early maturity and resistance to chocolate spot (Botrytis fabae) and rust (Uromycis fabae) along with high yield potential. Sakha 1 was evaluated through a series of yield trials conducted during 1994-95 and 1995-96 seasons in back-up research at Sakha Agric. Res. Station beside 8 on-farm trials conducted in Beheira, Kafr El-Sheikh and Dakhlia governorates in North Egypt during 1996-97, 1997-98 and 1998-99 seasons. Finally, Sakha 1 (x957) was evaluated in 18 demonstration plots selected in Kafr El-Sheikh (14) and Dakhlia (4) in 1999-00 season to demonstrate to farmers and extension staff the impact of planting Sakha 1 prior to cotton in cotton rotation comparing with farmers' cultivars. Data indicated that, Sakha 1 (x 957) produced the highest seed yields (1304, 12.97, 11.30, 12.55 and 8.95 ardab/fed.) among all tested breeding lines in the five growing seasons, respectively and exceeded the check cultivar Giza 461 by 17% in seed yield as an average of the five seasons. Also, over 18 demonstration plots, Sakha 1 exceeded farmers' cultivars in seed yield by about 2 ardab/fed. (28%) as an average. Data of foliar diseases reactions showed that over five seasons, Sakha 1 was markedly resistant to chocolate spot and rust, and almost similar to the resistant cultivar Giza 461. Concerning to earliness, Sakha 1 reached maturity earlier than Giza 461 by about 24 days
