Single Nucleotide Polymorphism Analysis Using KASP Assay Reveals Genetic Variability in .

This study employed single nucleotide polymorphisms (SNPs) to determine the genetic variability present in 26 isolates of from Louisiana, Mississippi, Arkansas, South Carolina, Georgia, Hawaii, and Alabama. Genomic DNA from reniform nematode was extracted and increased quantitatively using the process of whole genome amplification. More than 162 putative SNPs were identified, 31 of which were tested using a KASP kompetitive allele-specific PCR genotyping assay.

The Elusive Search for Reniform Nematode Resistance in Cotton.

The reniform nematode (Rotylenchulus reniformis Linford and Oliveira) has emerged as the most important plant-parasitic nematode of cotton in the United States cotton belt. Success in the development of reniform nematode-resistant upland cotton cultivars (Gossypium hirsutum L.) has not been realized despite over three decades of breeding efforts.
