Продолжительность вегетационного периода растений является важным биологически адаптивным и хозяйственно ценным свойством в селекции пшеницы. С ним связано большинство признаков и свойств сорта и в итоге его урожайность и качество зерна. Межфазный период «всходы – колошение» является менее вариабельным по сравнению с …

Mining of QTLs for Spring Bread Wheat Spike Productivity by Comparing Spring Wheat Cultivars Released in Different Decades of the Last Century

N. A. Shvachko, Maria Solovyeva, Irina Rozanova, I. A. Kibkalo et autres

Genome-wide association studies (GWAS) are among the genetic tools for the mining of genomic loci associated with useful agronomic traits. The study enabled us to find new genetic markers associated with grain yield as well as quality. The sample under study consisted …
