Expression of Genetic Variability and Character Association in Raspberry (Rubus ellipticus Smith) Growing Wild in North-Western Himalayas
The present investigation was carried out in various districts of Himachal Pradesh, Jammu&Kashmir and Uttarakhand States falling under north-western Himalayan region of India. As a result of sustained exploration, 170 wild raspberry genotypes were marked and studied for berry quality attributes. Variation ranged from 0.25 g-0.93 g for berry weight. Berry length varied between 6.31 mm and 14.46 mm, while, berry breadth was 7.02 mm to 15.91 mm. Variation in Total Soluble Solids (TSS) in berry ranged between 9.6oB and 18.6oB whereas, acidity in berries ranged between 1.02 and 1.72%. The range of variation was 2-4.90% for reducing sugars, 4.2° - 11.6° for non-reducing sugars and 2.4- 5.2 mg/100 g for ascorbic acid. Berry weight had significant and positive correlation with its length and its breadth. Berry length exhibited positively significant correlation with berry breadth.
