Abstract

Cross pollination in some of apples cultivar exists; also Iran is near the origin of apple trees so, large genetic diversity can be seen between Iranian cultivar. Also very famous apple cultivar is known in Iran for special flavor and taste. The name of this cultivar is Golab. This research was studied in the years 2010 and 2011 in Khorasan Razavi Province on Golab apple ecotypes to evaluate characteristics of Golab apples in Khorasan region, providing keywords for Identification, collect valuable ecotypes, preventing extinction and also use in apple breeding. Ecotypes were including: Golab Torbat Heidariyeh, Golab Sabz Pishras, Golab Kermanshah, Golab Kohanz, Golab Bahareh Shoghan. 31 qualitative and quantitative traits about fruit characteristics in a completely randomized design with 10 replicates to valuate these ecotypes were investigated. Average comparison showed that the greatest variability between cultivars was at the traits like: fruit weight, fruit firmness, fruit skin thickness, pH and TSS. The correlation results showed that the most significant positive correlation exists between fruit weight and stylar end width (0.92±0.06), fruit tail and fruit weight (0.87±0.07), Length to width ratio of fruit with fruit weight (0.85±0.08).
