Effects of specific Rht and Ppd alleles on agronomic traits in winter wheat cultivars grown in middle Europe
Original language description
Based on studies of the distribution of alleles at the important Rht and Ppd loci on wheat chromosomes 4B, 4D and 2D, different groups of winter wheat cultivars registered in the Czech and Slovak Republics during the period 1976-2007 were examined for arange of agronomic traits using official data from multi-location trials. Significant variation for all traits was detected among and between genotype groups. The frequent introduction of ´Rht-D1b´cultivars from the UK and Western Europe to the Czech Republic since 1995 has positively influenced lodging resistance and undoubtedly also yielding ability, but negatively affected winter-hardiness and bread making quality. An improved opportunity for earlier flowering cultivars with high winter-hardiness levels, in combination with high bread-making quality, can be obtained with genotypes carrying the Xgwm261 allele 192-bp that is probably indicative of the presence of Rht8.
