Validation of SNP markers for selection of semi-dwarf and peduncle extrusion in barley.

ABSTRACT: This study aimed to validate the use of two SNP markers associated to a sdw1 allele identified previously in a short barley genotype (ND23049) with an adequate peduncle extrusion which reduces predisposition to fungal disease development. First, the GBS SNP were converted in a KASP marker but only one of them, named TP4712, correctly amplified all allelic variations and had a Mendelian segregation in a F₂ population. To corroborate the association between TP4712 allele with plant height and peduncle extrusion, a total of 1221 genotypes were genotyped and evaluated for both traits. Out of the 1221 genotypes, 199 were F₄ lines, 79 were a diverse panel, and 943 were two complete breeding cohorts of stage 1 yield trials. To corroborate the association between the <
