POSSIBILITY OF APOMIXIS IN MUNGBEAN AND URDBEAN

Abstract

The crosses of mungbean and urdbean were confirmed in Fl by visualizing one of the prominent trait from male parent. The Fl crosses were harvested plantwise and were carried to F2 in plant to row progenies. Critical observations (Table. 1) made on morphological feature of every hybrid revealed that there was high percentage of hybrid plants (92.8, 93.6 per cent) in mungbean as compared to those in urdbean (30.4 and 50.0 per cent). The confirmed Fl plants were harvested separately and were grown plantwise in F2 progenies. Surprisingly, some of the F2 lines were very uniform without segregation. At the same time, the hybrids were very much distinct from theiF respective female parents and confirmed the presence of prominent trait of male parent seen in Fl' It indicated that they were derived from perfect hybridization.
