ABSTRACT
Guava (Psidium guajava L., 2n = 22) belongs to the family Myrtaceae, has got adequate genetic variation which will be an essential criteria for any crop improvement programme. The study of phenological stages and growth behavior is crucial to exploit these species in introgressing beneficial genes. Hence, the present study deals with the phenology of wild species of guava viz., Psidium guineense, P. chinensis, P. cattleianum and cultivar Arka Kiran. Phenological stages from time of leaf flushing to duration of fruiting were considered. The results revealed that synchronization was noticed in P. guineense and P. chinensis with Arka Kiran for peak flowering, duration of flowering and anther dehiscence, whereas P. cattleianum showed differential flowering time (June) compared to other species. P. cattleianum recorded lowest values for duration of flower bud initiation to full bloom, duration of flowering, peak flowering, per cent pollen germination, duration of flowering to fruit set and duration of fruiting.
