New Cultivars Derived from Crosses between Commercial Cultivar and a Wild Population of Papaya Rescued at Its Center of Origin
Table 4
Values and proportion of total variance explained by (a) a principal component analysis and (b) ratio of variability for each trait evaluated in the first three principal components obtained from the morphological analysis of seven traits at the F1 and F2 progenies resulting from the intraspecific cross L7 M22.
