Quantitative trait loci and candidate genes associated with freezing tolerance of winter triticale (× Triticosecale Wittmack).

ABSTRACT: Freezing tolerance of triticale is a major trait contributing to its winter hardiness. The identification of genomic regions - quantitative trait loci (QTL) and molecular markers associated with freezing tolerance in winter hexaploid triticale - was the aim of this study. For that purpose, a new genetic linkage map was developed for the population of 92 doubled haploid lines derived from 'Hewo' × 'Magnat' F₁ hybrid. Those lines, together with parents were subjected to freezing tolerance test three times during two winter seasons. Plants were grown and cold-hardened under natural fall/winter conditions and then subjected to freezing in controlled conditions. Freezing tolerance was assessed as the plants recovery (REC), the electrolyte leakage (EL) from leaves and chlorophyll fluo
