evaluation and selection of new lines from local red bean (phaseolus vulgaris l.) in chaharmahal & bakhtiari province by individual selection method

in order to select the suitable lines of red bean for chahharmahal & bakhtiari province, this experiment was conducted in lordegan & boldaji regions at 2001-2005. at the first year, single plants of local red bean (from lordegan, ardal, boldaji, dastgerd emamzadeh and gandoman regions) were selected at research farm for phenotypic characters, yield and yield components. at the second year, selected plants were sowed at lines with naz, sayyad and lordegan local variety as controls and analyzed by histogram method. at the third and fourth years, selected lines were sowed in rectangular lattice design and analyzed. at fifth year, selected lines were sowed at randomized complete block design (rcbd) with three replications in two regions (lordegan and boldaji). results of third year showed that l1, g17 and a15 lines were better than control naz (p<0.05). results of fourth year showed that d12, g11, d23, l22 and d32 lines were better than control sayyad (p<0.05). the results of fifth year showed that yield of d12, d3 & d10 lines were better (4370.4, 4370.4, 4351.6 kg.ha-1 at lordegan region and 1381, 1261.9, 1238.1 kg.ha-1 at boldaji region, respectively) than other lines and control (sayyad). these lines were selected from dastgerd emamzadeh local red bean and had adaptation to province climate conditions. thus these lines can be introduced to complementary experiments.
