Photoperiod response (Ppd) genes play a key role in fine-tuning of heading and flowering time
and adaptation of wheat to different agro -climatic conditions, which could increase crop yield.
The aim of this study was to analyse genotypes carrying different Ppd-1 alleles and their
influence on wheat phenology in growing conditions of the South-Eastern Europe. The
experiment was conducted with 10 well-adapted Serbian wheat varieties and 54 NILs of cv.
Paragon with single, double and triple doses of Ppd-1 alleles. The genotypes were sown in the
plot size of 2 m
2
at the location of Rimski Sancevi (45°20`N, 19°51`E), in randomized complete
block design with 3 replications. Heading and flowering time were recorded during three
growing seasons (2014, 2015 and 2017). The results showed that the genotype, growing season
and their interactions had significant effects on both analysed traits. The Serbian varieties (set
1) were signific...antly earlier regarding the heading and flowering time than cv. Paragon, and
most of the NILs. The NILs with introgressed single (set 2) insensitivity Ppd-1 alleles were
earlier than the original cv. Paragon in 2014 and 2015, but not in 2017. When the same alleles
were introgressed in a double dose (set 3), they significantly reduced heading and flowering
time in all seasons. The NILs with introgressed Ppd-1 null alleles and knock-outs (set 4) were
significantly later than cv. Paragon, and all other sets of genotypes. All indicated changes
caused by different Ppd-1 alleles were variable expressed in different growing seasons.
