DIALLEL ANALYSIS OF THE INHERITANCE OF QUANTITATIVE CHARACTERS IN CABBAGE (BRASSICA OLERACEA L. VAR. CAPITATA L.)

Abstract

Additivity of inheritance of length of inner core and days to maturity appeared to be rather important in this diallel cross of cabbage. Equal importance of additivity and dominance was observed in polar diameter and equatorial diameter of cabbage heads. Dominance contributed a large portion of genetic variation in yield while number of wrapper leaves varied with environment. However, there were indications that overdominance was also involved in all characters except polar diameter and days to maturity. The effective factors controlling each character ranged from one to three. The heritability values were high for polar diameter and days to maturity, moderate for number of wrapper leaves and length of inner core, and low for equatorial diameter and yield.
