Broad bean, Vicia faba L. is one of the important pulse crops in India. Broad bean is grown widely in the hilly terrains of Manipur. However, productivity of this crop is far below the national average and of its potential. Amongst the several abiotic and biotic factors for low productivity of broad bean, the damage caused by insect-pests which attack the crop from seedling to pod maturity stage is considered as one of the major production constraints. Among the different insect-pests of broad bean observed in Manipur, black aphid (Aphis craccivora) causes serious damage to the crop. It is, therefore, considered imperative to initiate investigation on this aphid of broad bean, one of the most important pulse crops of the state. On the other hand, very few research work has been conducted on black aphid resistant/tolerant broad bean varieties in the North Eastern Region of India. Given this backdrop, the present investigation was undertaken for screening of local broad bean (Vicia faba L.) cultivars of Manipur for their resistance reaction to Aphis craccivora (Koch.). The present investigation was carried out under the agro-climatic condition of Manipur with five local cultivars. The significant results generated from the study clearly revealed that Aphis craccivora was a regular pest of broad bean and maintained moderate level of population under valley condition of Manipur. Among the five cultivars tested in the present experiment, BLC-1 and BLC-2 were found to be suitable in terms of their resistance against black aphid. The cultivars may be recommended for the regions where aphid is a predominant pests for broad bean or can be included in future breeding programme to evolve better varieties.
