Phenotypic characterization of wheat–barley ‘Mv9 kr1’/‘Igri’ introgression lines in the field

Abstract

AbstractWheat–barley addition (2H, 3H, 4H, 6HS, 7H) and translocation (7D‐5HS) lines developed from a winter wheat ‘Martonvásári 9 kr1’ × winter barley ‘Igri’ cross were examined to determine how the added barley chromosomes (or segments) influence morphological and agronomic traits. The aim of our study was to investigate whether the advantageous traits of barley can be transferred to wheat by hybridization of the two species. The field experiment was carried out at UP Georgikon Faculty, Keszthely, during 2010–2011. Plants carrying the barley chromosomes had altered ontogenesis: days to 50% flowering, date of maturity, plant height, length and morphology of ear, flag leaf area, yield and components of grain yield. Regarding anthesis and maturity, the 7H addition line was the earliest, whereas the 4H addition was the latest to mature. Plant height and the length of spikes were decreased by the addition of 3H, 4H and 7H. Grain yield was decreased in addition lines 7H and 6HS and increased in addition 3H. Thousand grain weight was decreased in addition lines 2H, 4H and 6HS.
