بررسی ارزیابی صفات کمی و کیفی ارقام جدید سیب زمینی در کشت بهاره

The experiment conducted in six location in order to introduce new potato with high yield and good quality in order to replace of old varieties. Experiment design was Random Complete Block Design (RCBD) with three replication. Area of each plot was 9 square meter. Harvest done after deletion of one plant from first and end of each row. The results revealed varieties have differed for dry matter, specific gravity and starch. Relation among them were linear and positive.. The results of combine analysis variance for location and year revealed for the most characters, difference among varieties were significant and marketable yield for varieties of Chandramokhi, Goliat and Luca XI was more than others varieties. The results of combine analysis variance for year in all location revealed for total yield, marketable yield, percent of seed and vare tuber, number of main stem per plant, number of tuber per plant and lenght,difference among varieties was significant. The results of least significant difference (LSD) for dry matter, specific gravity and starch showed Camila, Ramola, Sponta, Aphrodit and Goliat had the most amount. In base of all trait for Chandramokhi, Goliat and Luca XI introduce for spring culture. Keywords: Potato varieties, Qualities and quantities characters, Introduce of new varieties .
