Sažetak
Elucidating photoperiod response is important for better understanding of adaptation to specific eco-geographic conditions and manipulation for wheat breeding purposes. Using a set of wheat near-isogenic lines differing in series of photoperiod sensitive alleles on the 2 group chromosomes, under conditions of eastern Croatia, we found that the allelic effects varied from 9.2 days for date of heading, 8.7 days for date of flowering and 11.7 days for date of physiological maturity for the “strongest“ allele Ppd-D1a vs. Ppd-D1b allele. Ppd-A1 locus showed strongest effects on grain yield for both allelic variants indicating it as useful alternative source of photoperiod insensitive alleles.
