Accelerating Sunflower Breeding with Genotyping by Sequencing
By Farhad Ghavami

Published January 14, 2019

Since 2010, Eurofins BioDiagnostics has worked together with the National Sunflower Association (NSA) and the USDA to create a high-density marker panel applicable for modern breeding programs. Unfortunately, the number of markers and the cost of the genotyping using the arrays were prohibitive and many breeders were unable to use the technology in their day to day breeding selections. More recently, the power of sequencing has made genotyping much more affordable...READ MORE

A Regulated Pathogen Challenges Global Tomato Seed Shipments
By Ravi Chitrampalam

Published December 12, 2018

Potato Spindle Tuber Viroid (PSTVd) is one of the top challenges to international tomato seed shipments due to strict phytosanitary regulations by importing countries. It reduces both the yield and marketable quality of the fruit. Seed is believed to be the source of PSTVd outbreaks in tomato and therefore, many countries impose rigid phytosanitary regulation on...READ MORE
