Genotyping of <i>Le</i> and <i>Af</i> Haplotypes in Dry Pea (<i>Pisum sativam</i> L.) with Field Trials: Short and Semi-Leafless Plants Are Not Always Better in Kazakhstan.

ABSTRACT: Lodging of pea plants has long been one of the greatest problems encountered at harvest, but it can be avoided with reduced plant height (PH) and increased number of tendrils. Two genes, Le (stem length), Psat5g299720, for PH, and Af (Afila), Psat2g173360, for semi-leafless types with multiple tendrils, were studied in the 6 most popular pea cultivars in Kazakhstan and in 60 pea accessions from a germplasm collection. ASQ molecular markers were developed based on an identified SNP in the Le gene. Two groups of 41 tall and 25 short (semi-dwarf) pea plants with average PHs of 83.6 and 56.3 cm, respectively, showed dominant and recessive Le alleles. Nine haplotypes of Af gene were found in the same set of pea genotypes and the PsPALM1b (Psat2g1
