Assessment of heterosis based on parental genetic distance estimated with SSR and SNP markers in upland cotton (Gossypium hirsutum L.).

ABSTRACT:

Background

Heterosis has been extensively utilized in different crops and made a significant contribution to global food security. Genetic distance (GD) is one of the valuable criteria for selecting parents in hybrid breeding. The objectives of this study were to estimate the GD between parents using both simple sequence repeat (SSR) markers and single nucleotide polymorphism (SNP) markers and to investigate the efficiency of the prediction of hybrid performance based on GD. The experiment comprised of four male parents, 282 female parents and 1128 F₁, derived from NCII mating scheme. The hybrids, their parents and two check cultivars were evaluated for two years. Performance of F₁, mid-parent heterosis (MPH), and best parent heterosis (BPH) were evaluated for
