Abstract
In guava significant correlations were observed between duration of flowering with their respective seasons and their yield and total yield. Duration of flowering was positively correlated with yield of respective seasons. Fruit weight was positively and significantly correlated with fruit size (r=0.860**) and fruit volume (r=0.981**). T.S.S. was positively and significantly correlated with reducing sugar (r=0.586**) and total sugar (r=0.683**). Acidity also positively and significantly correlated with reducing sugar (r=0.497**) and total sugar (r=0.417*). Reducing sugar was positively and significantly correlated with total sugar (r=0.888**). Yield was significantly and positively correlated with fruit size, weight and fruit volume (r=0.327*).
