Stability of yield and fruit quality in promising peach cultivars
Апстракт
Yield and fruit quality (fruit weight, reducing sugar content, sucrose content and total acids content) were studied in 20 introduced peach cultivars. To evaluate the stability of those characteristics in the agro-ecological conditions of Belgrade surroundings, bi and S2di were applied. 'Adriana' had the highest yield and content of reducing sugars, 'Aurelia' the highest fruit weight, 'Pegaso' the highest sucrose content, and 'Croce del Sud' the highest total acids content. Values of bi coefficient indicated that 'Sirio' had the highest stability of yield 'Iris Rosso' the highest stability of fruit weight and content of reducing sugars, 'Aurelia' the highest stability of sucrose content, and 'Emilia' the highest stability of total acids content. Values of S2di, despite being relatively high, did not show any statistical significance, which indicates a more significant deviation from regression and unsatisfactory stability of the studied genotypes. The results of the present work confir...m that bi, being a stability parameter, is more important than S2di in heterozygous genotypes, the genotype of a majority of fruit cultivars, therefore of peach itself.
