HORTSCIENCE, 35:310-312. 2000. Interpretive Summary: Nebraska has ranked number one in the US in the production of Great Northern dry beans (Phaseolus vulgaris L.) with a production of 8,412,698 kg in 1998. Rust, common bacterial blight, and white mold diseases cause serious reductions in bean yield and seed quality in Nebraska. Halo blight has been observed in some years, but is not considered a major problem. There is a need to develop an adapted high yielding Great Northern variety with resistance to strains of the above bacterial and rust pathogens pre- vailing in Nebraska, and also with an architectural avoidance of white mold. Presently there is no Great Northern variety with those trait com- binations. The release in 1998 of the Great Northern 'Weihing' variety with the above combination of traits should provide benefits to growers, as it should ensure improved yield, quality, and reduce the need to apply pesticides.
Technical Abstract: The principal merits of "Weihing" are its resistance to prevailing strains of rust, common blight, halo blight in NE, and a moderate avoidance to white mold due to its upright and porous plant canpoy. Seed production is expected to be successful in Idaho due to BCMV resistance. BCMV is not a problem in Nebraska. The multiple disease resistance of 'Weihing' reduces disease risk and lowers cost of production for growers. 'Weihing' is more upright than 'Beryl' and 'Harris' thus facilitating furrow irrigation and cultivation.
