Abstract

                                An extra early duration Avarai (Lablab purpureus var typicus - Garden bean) culture COLT 22/1 was developed by hybridization and pedigree breeding. It is a hybrid derivative of CO 9 x CO 4, an extra early duration, dwarf, erect and high yielding culture. It matures in 70 - 75 days as vegetable crop and 80 - 85 days as seed crop. The culture COLT 22/1 has no tendrils and needs no clipping which saves 50 man days ha-1. The total number of pods from a single plant in all the three pickings vary from 30 - 45 and the mean single plant yield varies from 95-150 g. After first picking of vegetables, the crop can be allowed to mature and can be harvested with in 80 - 85 days for seed purpose. It has recorded an average yield of 7984 kg ha-1 of tender pods as against 6518 kg ha-1 of pods by CO 13 and an increase of 22.49% over CO 13.

Key words : CO (Gb) 14, early duration, photo insensitive.
