Use of the molecular markers for identification Co gene determining columnar growth habit in apple
Abstract
Columnar growth habit is important breeding trait of apple. The use of molecular markers allows in the early stages of ontogenesis to determine with high reliability the identified columnar genotypes and to reduce the time of the selection process. The results of the identification of columnar apple forms using molecular markers С18470-25831, Mdo.chr10.12, 29f1-jwl1r and 29f3-30r were revealed. Markers C18470-25831, Mdo.chr10.12 does not allow high reliability to differentiate apple genotypes for by growth habit. Markers 29f3-30r and 29f1-jwl1r flanking the insertion in the Co locus of the columnar forms the most reliable are the identification of columnar genotypes. That insertion in the genome of non-columnar apple cultivars is absent. With the use markers 29f3-30r and 29f1-jwl1r the dominant allele of the Co gene was identified in the genome of columnar cultivars Valuta, Vasyugan, Geyser, Gotika, Zelyonyy shum, Kaskad, Moskovskoe ozherel’e, Ostankino, President, Priokskoe, Strela, Teleymon.
