title: Identification of Ppd-B1 alleles in common wheat cultivars by CAPS marker.
abstract: Photoperiod response is a major determinant of the duration of growth stages in common wheat. In common wheat, many genes play a role in determining flowering time, but the Ppd genes located on the homoeologous group 2 play a major role. Of these Ppd-B1 is located on the short arm of 2B. In 107 common wheat cultivars grown in Poland and neighboring countries, the identification of Ppd-B1 alleles using in-del analysis by using a CAPS markers was investigated. 87 cultivars were shown to carry dominant Ppd-B1 alleles. This shows that Ppd-B1 alleles is have been widely used in common wheat breeding programme in these countries. Recessive ppd-B1 alleles were found only in 20 cultivars (12 Polish, 5 former Soviet Union, 2 German, 1 Swedish).
