Effect of screening in different breeding generations on yellow mosaic virus incidence in mungbean

摘要

Mungbean (Vigna radiata L. Wilczek) commonly known as 'green gram' is one of the important pulse crop of India. It is cultivated during summer and kharif season in north India, whereas, in southern India it is cultivated in kharif and rabi. It is tolerant to drought and can be grown successfully on well drained loamy to sandy loam soil in areas of erratic rainfall. In India it is the third important pulse crop after chickpea and pigeonpea. India is the largest producer of mungbean in the world. It accounts for 65% of mungbean area and 54% of world's production. It covers 3.34 million hectare with a production of 1.06 million tonnes (2004-05). Orissa, Maharashtra, Andhra Pradesh, Madhya Pradesh, Gujarat, Rajasthan and Bihar are the major mungbean growing states in India. In general, the productivity of mungbean is very low and unstable, primarily due to abiotic and biotic stresses. Diseases are found to be the most important biotic stress in mungbean cultivation.
