Research Project: Developing molecular markers and a vocabulary for breeding fruit texture in table grapes

Location: Crop Diseases, Pests and Genetics Research

Project Number: 2034-21220-007-29-T
Project Type: Trust Fund Cooperative Agreement

Start Date: May 1, 2020
End Date: Apr 30, 2021

Objective:
The objectives of the proposal are to 1) Develop genetic mapping populations segregating for fruit texture and juiciness 2) Phenotype grape germplasm for fruit quality traits 3) Identify molecular markers associated with fruit texture and juiciness.

Approach:
We propose to phenotype grape breeding germplasm and individual clusters from a segregating mapping population for texture chewiness, and springiness) and juiciness using a Kramer Shear cell equipped to a universal testing machine (UTM).
