| Popis: | `White Half Runner' is a popular green bean (Phaseolus vulgaris L.) cultivar in the southern Appalachian region of the United States. The cultivar is highly susceptible to rust and virus diseases. Nine breeding lines with `White Half Runner' parentage were compared to `White Half Runner' for rust tolerance, yield, and pod quality in 1998 and 1999 field trials at Crossville, Tenn. The BelTenn selections were developed by USDA plant breeders and the UT selections were developed by University of Tennessee plant breeders. Selections `BelTenn-RR-2', `BelTenn 4-12028', `BelTenn 4-12046', `BelTenn 4-12053', `BelTenn 5-2717' and `UT-96-3' were resistant to rust. Only `UT 96-4' had lower yields than `White Half Runner' in 1999. The BelTenn lines had slightly smaller pods, and the UT selections had larger and rougher pods than `White Half Runner'. `BelTenn-RR-2' wasreleased in 1995 as a breeding line with rust resistance and pod quality similar to `White Half Runner'. Further selection of BelTenn-RR-2 by a private seed company led to the naming of a cultivar named `Volunteer White Half Runner'. |
