TAILIEUCHUNG - Determination of the apomictic fruit set ratio in some Turkish walnut (Juglans regia L.) genotypes

Female flowers were bagged and/or pollinated with pollen of the apple cv. ‘Golden Delicious’ (Malus x domestica Borkh.), and the apomictic fruit set was determined 8 weeks after anthesis. | Turk J Agric For 30 (2006) 189-193 © TÜB‹TAK Determination of the Apomictic Fruit Set Ratio in Some Turkish Walnut (Juglans regia L.) Genotypes Bekir fiAN, Hatice DUMANO⁄LU* Ankara University, Faculty of Agriculture, Department of Horticulture, 06110, Ankara - TURKEY Received: Abstract: This study was carried out to determine the amount of apomictic fruit set in 10 Turkish walnut (Juglans regia L.) genotypes in 2001, 2002 and 2003. Yalova-1, fiebin, Bilecik, KR-1, KR-2, fien-2, 07-KOR-l, Tokat-1, Kaman-1 and Kaman-5 cultivars and selections were used in the experiment. Female flowers were bagged and/or pollinated with pollen of the apple cv. ‘Golden Delicious’ (Malus x domestica Borkh.), and the apomictic fruit set was determined 8 weeks after anthesis. The percentage of apomictic fruit set without pollination ranged from to in 5 walnut genotypes, namely Yalova-1, Bilecik, 07-KOR-l, Tokat-1 and Kaman-1, in the first 2 years. In the third year, the highest apomictic fruit set () was obtained from Tokat-1 after pollination with apple pollen. Apple pollen did not induce apomixis in the other 4 genotypes. The results indicated that apomictic fruit set is insufficient for economical seed and crop production in these ten Turkish walnut genotypes.
