Ghaffar, a New Variety of Chitti Bean

Ghaffar cultivar was introduced during 1995 in the form of F2 generation from the International Research Center for Tropical (CIAT) for the first time. Adaptability tests were performed in three areas including Khomein, Boroujerd and Zanjan during 2008 to 2010 that line of Ghaffar was superior in compared to Khomein control. This cultivar in Zanjan by producing 4474 kg ha-1, Khomein 2922 kg ha-1 and Boroujerd by producing and 2965 kg ha-1, which was 32.1%, 16.1% and 27.1% respectively was superior than Khomein as control. Overall in 3 locations and 3 years Ghaffar produced 3376 kg ha-1 more grain yield than control that was about 25.8% increase in grain yield. During 2002 resistance of 36 bean genotypes evaluated to two-spotted mite in a rectangular lattice design. In this study, Ghaffar was the one of the genotype with high-yield and had the highest resistance to the two-spotted mite based on composite index of resistance. Drought tolerance tests were performed during 2009-2010 and yield of Ghaffar was higher than Sadri as control, in normal irrigation and drought stress by about 25.2 and 57% per hectare respectively. Also in 2010, research project extension was conducted and Ghaffar produced 2824.5 kg ha-1 which was 27% more than control. Finally, according to several tests, Ghaffar line in terms of yield, compatibility, marketing, pest resistance and drought tolerance showed superiority to Sadri control. Line Ghaffar has high yield with plant type 2 (indeterminate standing), business class Cranberi, 100-grain weight 40 grams.
