Abstract

This study was carried out to purify Chitti bean cultivars. In the first year, 11 populations were collected from main Chitti bean cultivating areas. Based on some criteria such as higher yield, earlier maturity, more pods and tolerance to pests and diseases, single plants were selected. In the second year, seeds of each selected single plant as well as controls (Talash and COS16) were managed to compare in a preliminary yield trial. 23 lines were chosen based on the traits as mentioned above. In the third year, these lines along with two controls were planted in a 5*5 square Lattice design in two replications. From this experiment, nine superior lines were selected. These lines along with three controls were compared in a RCBD with 4 replications to distinguish the best lines. In the fifth year, from the 6 last year selected lines, three pure lines showed good performance to be selected. To determine environmental compatibility, yield and other agronomic traits, these three lines and four native pure lines from Fars province were evaluated. Results showed that there were significant differences among lines. Z1 from Zanjan and E10 and E9 from Eghlid were the best lines with 2546, 2328 and 2313 kg/ha seed yield, respectively.
