Sažetak
Wheat is dominant crop in temperate climate and its success depends on its adaptability and high yield as well as specific quality traits. Large natural variation of this species is enabled by its hexaploid genome structure. Adaptation of wheat genotypes to diverse environmental conditions is under strong influence of flowering time. The aim of this study was to detect presence of functional markers for plant height, response to photoperiod and vernalisation requirement among 70 elite wheat germplasm. Selected cultivars, originated from Croatia, Serbia, Italy Austria, Germany, France, Hungary, Russia, were evaluated for plant height and flowering date in field trial located in Eastern part of Croatia. DNA extraction from three phase leaves was carried out by CTAB method. Average plant height was 88.92 cm, ranged from 62 to 159.32 cm with CV of 19.23%. Days to heading ranged from 142 to 119 days with CV of 4.06%. Our results indicated that Rht-B1b, Rht8 (192bp), Ppd-D1a dominate with frequencies of 62%, 68%, and 72% respectively, followed by Rht-D1a, Rht-D1b and Ppd-D1b alleles. Seventeen cultivars with Rht-B1a and Rht- D1a had plant height ≥98 cm, while 25 cultivars carrying dwarf alleles had plant height from 62 to 96 cm. Among Croatian cultivars Vrn-A1a was detected in only one cultivar, Vrn-A1c in three while vrn-A1 dominated with 92%. Prevalence of vrn-B1 and vrn-D1was recorded with 95% and 100%
