4th International Walnut Symposium, Bordeaux, Fransa, 12 - 16 Eylül 1999, ss.521-525
This study was carried out on the walnut cultivars Bilecik, Yalova 1, Yalova 3 and Yalova 4 to compare propagation and sapling quality of walnut with patch budding at dormant season in Tokat province ecological conditions. The research was conducted in 1996-97 years. Successful budding ratios in walnut varieties were found as 90 % with Bilecik, 85 % with Yalova 1, 88 % with Yalova 3 and 90 % with Yalova 4. Also, the ratios of budding sprouted at the same year were determined as 3.70, 9.80, 3.77 and 20.37 %, respectively. While the highest sapling yield was obtained from Bilecik variety with 53 %, the lowest sapling yield was obtained from Yalova 4 variety with 28 %. The sapling yield of the other varieties were found as 43 % and 41 %, respectively. In addition to compare the growth values among varieties the diameters(mm) and the heights (cm) of rootstock and scions were measured. The diameters and heights of seedlings were found statistically different because walnut seeds are heterozygous. Therefore the diameter and height degrees of varieties were found statistically different too. While Yalova 1 variety gave the best height (244.5 cm) growth, Yalova 4 variety gave the lowest height (179.7 cm) and diameter (17.28 mm) growth.
