ABSTRACT
It is utmost desire for plant breeders to know the extent of relationship between yield and its various components, which will certainly facilitate selection of desirable characteristics. So an attempt was made to calculate the correlation coefficients and path coefficients of yield and its yield contributing characters in Malus domestica. Apple yield was significantly and positively correlated with fruit weight, trunk girth, tree height, canopy spread, Flower Density Index and fruit set. Fruit weight made the largest per cent contribution of 45.34 to apple yield followed by Flower Density Index which contributed 5.26. The highest indirect per cent contribution to apple yield was obtained through fruit weight and Flower Density Index. Thus fruit weight and Flower Density Index were the most important yield components of apple crop which should be exploited through a breeding programme for improving its yield potential.
