Abstract:	An intercrossed population was developed using the ten most resistant cultivars or experimental lines and the ten most resistant plant introductions available in 1975. Each cycle of selection required one year and involved selecting the ten most resistant lines before flowering, and then crossing them in a diallel for the next cycle of selection. There was a significant linear improvement in mean chlorosis score from cycle 0 to 2. The average genetic gain per cycle ( 0.2 units) was 9% of the cycle 0 mean. The results indicated that resistance is influenced by genes with additive effects and that early generation selection for resistance should be effective
