TAILIEUCHUNG - Incompatibility alleles expressed in pollen of Turkish hazelnut cultivars
Sphorophytic pollen-stigma incompatibility is a characteristic of the genus Corylus. Incompatibility alleles expressed in the pollen of Turkish hazelnut cultivars were identified. Cultivars were selected from the field collection at Giresun, and were used as the pollen parents. | Turk J Biol 29 (2005) 111-116 © TÜB‹TAK Incompatibility Alleles Expressed in Pollen of Turkish Hazelnut Cultivars Veli ERDO⁄AN Department of Horticulture, Faculty of Agriculture, Ankara University, 06110 D›flkap›, Ankara - TURKEY Shawn A.

Incompatibility alleles expressed in the pollen of Turkish hazelnut cultivars were identified. Cultivars were selected from the field collection at Giresun, and were used as the pollen parents. Tester plants, whose S-alleles were known, were located in Ankara and Corvallis. Compatible crosses produced masses of long and parallel tubes while incompatible crosses produced very short tubes that often curved or ended with a pronounced bulb. The incompatibility alleles S2, S5, S8, S10, S12, S21 and S24 were identified in the pollen of Turkish cultivars. Pollen of Palaz and Yuvarlak Badem expresses S2, pollen of Fofla, Mincane and Sivri expresses S8, pollen of Kan, Cavcava, Ac› and Kargalak expresses S10, pollen of ‹ncekara, Kal›nkara and Uzunmusa expresses S21, pollen of Yass› Badem expresses S5, pollen of Tombul expresses S12 and pollen of Çak›ldak expresses S24.
