Abstract:
Clusterbean [Cyamopsis tetragonoloba L.] Taub is an important leguminous crop of kharif season in arid and semi-arid region of India. It is affected by several fungal, bacterial and viral diseases but stem rot incited by Sclerotium rolfsii is emerging as severe problem in recent years and cause yield losses ranging from 50-70 per cent depending upon disease severity. The total sugar, reducing sugar and non- reducing sugar were higher in healthy stems as compared to diseased stems in all the tested varieties i.e., RGC-936, RGC-1003 and RGC-1033. Maximum reduction in total sugar and non-reducing sugar was found in RGC-936, followed by RGC-1003 and RGC-1033. Total protein and total phenol content were higher in diseased stem as compared to healthy tissues of all the tested varieties. Maximum increase in total phenol was observed in diseased stems of RGC-1033 followed by RGC-1033.
