بررسی پتانسیل تولید مینی‌تیوبر کلون‌های پیشرفته سیب‌زمینی متوسط دیررس در سیستم هواکشت

This study was performed in order to investigate mini-tuber production potential of potato promising clones of mid-late maturity for achieve the greatest potato mini-tuber number, weight and quality in Aeroponic system for two years (2012-2013) in the laboratory and greenhouse of Ardabil Sabalan Behparvar Company. Three numbers of promising clones (397081-1, 397097-2 and 397082-10) and Agria cultivar were evaluated as completely randomized design with three replications. During growth period and after harvest some important traits as: the plant height, main stem number per plant, mini-tuber number and weight per plant and per square meter and mini-tuber weight average per square meter were measured. Analysis of variance showed that between clones in traits of mini-tuber number and weight per square meter, mini-tuber weight average per square meter, plant height and main stem number per plant there were significantly differences. The mid-late mature promising clone of 397081-1 had high in traits of mini-tuber number and weight per square meter, mini-tuber weight average per square meter and plant height. In conventional system, were harvested 200 mini-tubers per square meter. In this experiment, the numbers of mini-tubers per square meter in mid-late maturity promising clone of 397081-1 were produced 2766 numbers. The 2566 numbers of mini-tubers per square meter were obtained in aeroponic system more than conventional systems.
