Release of three new Guatemalan bean varieties tolerant to golden mosaic virus

In search of tolerance to BGMV, screening of 41 F2 and F3 populations of a group of crosses from CIAT was started in Guatemala in 1977. In 1978, some F4 F5 and F6 selections were evaluated in preliminary yield trials with high infection pressure. In 1979 the best F7 and F8 lines were widely tested in NE, SE and S. coastal Guatemala on the basis of 50 regional trials, 3 new bean BGMV-tolerant var. were evaluated: (1) ICTA-Quetzal (Porrillo Sintifico x ICA Pijao), highly tolerant to BGMV, wide adaptation, intermediate maturity, indeterminate growth habit, bush type; (2) ICTA-Jutiapin (ICA Pijao x Turrialba-1) tolerant to BGMV, adaptable to regions at 400-1200 m art., intermediate maturity, indeterminate growth habit, bush type; and (3) ICTA-Tamazulapa (ICA Pijao x Turrialba-1) moderately tolerant to BGMV, wide adaptation, intermediate maturity, indeterminate growth habit, bush type with vines.
