Varietal description of sorghum phenotypes for registration

Abstract

The goal of a plant breeding is the generation of new varieties that become agricultural inputs for farmers. For this, it is necessary to verify the genetic identity of the materials and have the breeder's registration and title. The University of Guadalajara has generated varieties and quality sorghum hybrids that must be released to the public. This work was developed to establish the methodology of varietal characterization, an essential requirement for obtaining a breeder's title before the National Seed Inspection and Certification Service (SNICS). For this, 2 andro-sterile lines (A) and a fertility restoration line (R) were described, in two locations and two production cycles. By establishing according to ranges of variation and stability, the appropriate sample size and differential phenotypic characters that facilitated identification.
