Ofogh, a new red bean cultivar with early and large grains

The red bean Ofogh cultivar introduced to Iran in 1994 under the name of Line D81083 from the International Center for Tropical Agriculture (CIAT) and was evaluated in several experiments with breeding, agro-techniques, plant protection and onfarm aspects. This cultivar with grain yield of 2324 kgha-1 had 11% higher yield compared to the Goli check cultivar in evaluation of adaptability of red bean cultivars in Khomein region. Based on its grain yield and also due to early maturity, plant stand type, excellent grain size and good marketing this line was selected for further studies. Ofogh cultivar had the lowest yield reduction under drought stress conditions and had a lower susceptibility index and higher drought tolerance index compared to Goli check cultivar. Also, with an efficiency of 0.28 kgm-3 under drought stress conditions, it had a good water use efficiency. This cultivar is resistant to bean common mosaic virus disease. Also, it is 20-25 days early mature than conventional red bean cultivars and cut down at least four irrigations, where under flood irrigation conditions it will save at least 3400 m3 of water consumption. This cultivar is recommended for areas where cultivation of beans is not possible due to early autumn cold damage, or in the areas where bean planting time is delayed in spring due to coincidence with irrigation of autumn crops such as wheat, barley and canola.
