ABSTRACT
Correlation studies with 11 early and 6 medium maturing advanced potato hybrids were conducted at the experimental field Agricultural Research Station, Madenur, Hassan during kharif season of 2010. Results in early maturing potato hybrids indicated that number of leaves, tuber weight per plant and marketable tuber yield per plot were shown significant positive correlation with tuber yield per plot in both genotypic and phenotypic levels. Results in medium maturing potato hybrids indicated that tuber yield was positively and significantly correlated both at phenotypic and genotypic levels with number of tubers per plant and marketable yield per plot. Since, the association is in desirable direction, selection for these traits may ultimately improve the yield.
Key words :
Genotypic and Phenotypic correlation, Potato hybrids.
