STUDY ON VARIATION, HERITABILITY AND CORRELATION IN OPEN POLLINATED CULTIVARS AND NEW BREEDING LINES OF LATE HEAD CABBAGE

The purpose of the present investigation was to establish the genetic and phenotypic variability, broad sense heritability and phenotypic and genetic coefficients of correlation for some characters in open pollinated cultivars and selected new breeding lines of late head cabbage.
The study was done during 2005–2007 with 4 cultivars and 4 lines of head cabbage grown by the technology for late field production.
It was established that the highest phenotypic and genetic coefficient of variation more than 30% was determinate for the weight and diameter of head.
Broad-sense heritability was high for most of the investigated characteristics and varied from 51% to 92%. The relationships between vegetation continuation and cabbage weight (r_g = 0.819***), leaf rosette weight with cabbage weight and diameter (r_g = 0.770** and r_g = 0.693*), cabbage weight with head diameter and shape (r_g = 0.686* and r_g = 0.615*) and the correlation between cabbage shape and firmness (rg = 0.683*) are with high coefficients of genetic correlations.
