ABSTRACT
In the south part of Ukraine the haplotype of Rht8c and Ppd-D1a genes is highly distributed among modern bread wheat varieties. During the time of breeding program it has been selected as one of the most important adaptive complex for plants of this region. Genetic distance between Rht8c and Ppd-D1a was clarified.

85 winter bread wheat varieties and lines that have been developed mostly in Ukraine were analyzed with NIR for parameters of hardness and protein content. The hardness data were compared with the data of puroindoline gene alleles analysis done earlier and the published data. Significant variation of parameters of hardness was revealed when there was low polymorphism of puroindoline genes indicating the presence of additional genes that influence the hardness parameters.
