Abstract:
In order to determine the correlation of important agronomic characteristics and yield of medium late genotypes of head cabbage (Brassica oleracea var. capitata L.), both reciprocally and with the yield, a collection of Institute for Vegetable Crops Smederevska Palanka, Serbia has been used. The research has been conducted, under field conditions, during 2009 and 2010. Twelve middle late cabbage genotypes have been included (Be; Lin 3; Gol; Rubin; P44; K.G.; Vod; K7; SM-4; Triumf; Katun; Scc) collected from different localities. Thirteen phenotype characteristics have been observed: plant weight, head weight, rosette weight, head circumference, head height, head width, number of rosette leaves, rosette height, rosette width, plant height, external core length, internal core length and vegetation period. Beside the phenotype characteristics, the yield has also been measured. The highest Pirson’s correlation coefficients found between the agronomic traits were: yield and head weight (r=0.99); length of vegetation period and head width (r=0.93); head weight and head height (r=0.92); yield and head height (r=0.92); head width and head height (r=0.90). The results of correlation analysis show that 30% of estimated correlations were statistically significant. Head weight and head height, showed the highest correlation coefficients with the yield.
