Technique for crossing and advancing multiple generations for mungbean (Vigna radiata L.)

Abstract

Mungbean (Vigna radiata L.) Wilczek (2n=2×=22) is an important grain legume cultivated in South-east Asia, Africa, South America and Australia (Shanmugasundram 2007). About 90% of mungbean production occurs in South Asia, where India is the largest producer. It is consumed in various forms like, seed as a good source of easily digested dietary proteins and amino acids. Young pods and sprouts are consumed as vegetable for vitamin and mineral supplement (Engel 1977). Its plant parts are used as fodder for animal and green manure to improve soil health in rice-wheat cropping system (Sharma et al. 1995; Bhuiyan et al. 2009; Yaqub et al. 2010). It is grown as a sole crop as well as a major component in various cropping systems owing to its ability to fix atmospheric nitrogen, rapid growth, and early maturity. Mungbean being a photo insensitive crop is grown in a wide range of climatic variations (Tiwari and Ramanujam 1976) and ideal for catch, inter and relay cropping in many countries (Ali et al. 2000). Because of wide adoptability at various temperature ranges, this crop is likely to be most suitable under currently rising global temperature
