CORRELATION BETWEEN ECONOMICALLY VALUABLE TRAITS OF PARTHENOCARPIC CUCUMBER FOR PLASTIC GREENHOUSES

Abstract

The article presents the statistical analysis of correlations between economically valuable traits of cucumber for plastic greenhouses. The positive correlation between yield and number of fruits per plant (r = 0.82), yield and duration of fruiting period (r = 0.85), number of flower buds and the number of fruits per plant (r = 0.74), duration of fruiting period and number of fruits (r = 0.73), yield and number of flower buds (r = 0.68), downy mildew and powdery mildew affecting (r = 0.77) are identified. The negative correlations between the period from germination to fruiting and the number of fruits (r = –0.78), yield and the period from germination to fruiting (r = –0.81), yield and downy mildew (r = –0.64), yield and powdery mildew (r = –0.60) are determined. At the same time correlation between the olive spot and downy mildew affecting (r = 0.02), olive spot and powdery mildew affecting (r = 0.05) is not identified.
