Title	Polymorphism of waxy proteins in Spanish durum wheats
Journal	Plant Breeding
Year	2000
Volume	119
Pages	277-279
Author	Nieto-Taladriz MT Rodriguez-Quijano M Carrillo JM
Abstract	A collection of 547 durum wheats (103 cultivars and 444 landraces) from Spain was analysed for waxy protein composition. The electrophoretic patterns showed low polymorphism. At the Wx-A1 locus, 99.8% of the wheats had the Wx-Ala allele and only one had the null Wx-Alb allele. The Wx-Bl locus was more polymorphic and four different alleles were detected: Wx-Bla (41.3%), Wx-Blc (42.6%), a new allele, not detected before in bread wheat and named Wx-Blf (16.0%), and the null Wx-Blb allele, found for the first time in one durum wheat. Eleven durum wheats with different allelic composition at the Wx-l loci were analysed for amylose content. Wheats with the Wx-Bla allele had a lower amylose content than those with Wx-Blc or Wx-Blf. The lowest amylase content was found in the only durum wheat having the null Wx-Blb allele.
