Assessment of frost tolerance of wheat double haploids by gliadin electrophoresis.
Original language description
The relationship betweeen gliadin alleles, known to mark frost tolerance, and actual frost tolerance was investigated in 52 doubled haploids (DH) from the cross FloridaxVlada. Frost tolerance was expressed as a percentage ofplant winter survival in potsplaced at different heights above the ground. Gliadin allelic blocks (GLI) were determined by starch electrophoresis. From the sic GLI, known as frost tolerance markers, GLI 1B1, GLI 1D5 or GLI 6D2 were present in 27, 27 or 31 DH, respectively. A weak, but significant correlation of r=0.29 was found in the DH between their survival and frost tolerance prediction values based on the presence of the gliadin frost toleranec markers. The average survival of DH with glisdin tolarence marker GLI 1B1 or GLI 6D2, but not with GLI 1D5, was significantly higher than the survival of DH without these blocks. The DH without any gliadin frost tolarence marker had the lowest survival. Some gliadin genes thus can be used as frost tolerance markers in s
