A genetic-physiologic study of iron-induced manganese chlorosis in beans was initiated. The experiments were conducted in a greenhouse in sand-culture. Soil culture was used for crossing and seed multiplication only. Approximately 60 breeding lines of navy beans (phaseolus vulgaris L.) were planted under two nutrient conditions; normal (control) and screening (5.0 ppm iron and zero manganese). Differential chlorotic symptoms were noted on plants in the screening solution 3-4 weeks after planting. On the basis of the appearance, two extremely chlorotic (50 and 80) and two nonchlorotic lines (40 and 47) were selected for further studies. The analysis of plant parts indicated that the chlorotic and nonchlorotic lines differ in the pattern of distribution of iron and manganese. Chlorotic lines transport relatively more iron and less manganese to the shoot, whereas the converse is true for nonchlorotic lines.
