Effect of Vrn and Ppd genes on frost resistance in bread wheat






Tsitologiya i Genetika 32(6): 59-62

Effect of Vrn and Ppd genes on frost resistance in bread wheat

The dominant alleles of the major vernalization requirement (Vrn) and photosensitivity (Ppd) genes of bread wheat affect the level of frost resistance. The degree of seedling injury correlates closely with the speed and rate of juvenile growth and corresponds within certain genotypes to heading date acceleration. Sets of lines congenic and isogenic for the 3 major Vrn and Ppd loci in various backgrounds were studied in the phytotron.
