Genetic variability and correlation analysis in guava

Genetic variability, heritability and genetic advance of 13 fruit characters in 15 guava genotypes were studied. Significant differences were observed for almost all the traits under study viz., fruit weight, fruit length, fruit diameter, acidity and ascorbic acid with high value of GCV, PCV, h² and GA which, makes them prime traits for direct selection. TSS, total sugars, reducing and non-reducing sugars with high values of h² and nearly moderate values of GA are other important characters which have to be considered for selection. The fruit yield/tree was positively and significantly correlated with fruit weight and fruit length.
