Comparative single nucleotide polymorphism analysis of maize Iodent and BSSS germplasms

Popis výsledku v původním jazyce

The analysis of single nucleotide polymorphisms of 107 maize inbreds was performed on 384 special single nucleotide polymorphism (SNP) markers to receive their unique certificates and determine their degrees of affinity and heterotic potential. All inbreds were selected in the steppe zone of Ukraine, among them, 39 inbreds belonged to the Iodent and 28 inbreds to the BSSS germplasms. 40 inbreds of the Iodent/BSSS breeding group developed after hybridization of Iodent and BSSS, were also analysed by the same SNP markers. The average homozygosity of lines amounted to 98.05%, and the genetic diversity was 0.1746. According to pairwise SNP distances, lines of the Iodent and BSSS pedigrees formed two separate clusters, while the Iodent/BSSS lines were distributed among them. The allelic patterns of SNP markers specific for Iodent and BSSS inbred lines in comparison with each other and with the original inbreds P165, B14, B37, and B73 were formulated and discussed. Inbreds within the Iodent germplasm were on average much more closely related (GD = 0.2494) than those within the BSSS germplasm (GD = 0.3900) and the Iodent/BSSS breeding group (GD = 0.3967). The potential of the heterotic model IodentxBSSS was assessed as high (mean GD = 0.4509). Based on SNP distances, inbreds have been recommended for the development of single cross heterotic hybrids, sister hybrids, and initial populations for subsequent breeding cycles.
