Portrait of Patrick J. Conner

UGA Tifton Campus


I am the research leader of the University of Georgia's pecan breeding program which was initiated in 1998 when I was hired. In addition, in 2004 I became the new leader of the UGA muscadine grape breeding program which has been in existence for over 100 years. Both of these are active breeding programs which have the goal of producing new cultivars adapted for the southeastern U.S. growing region. While our breeding programs primarily revolve around the traditional fruit breeding methods of making crosses and evaluating seedlings, we are also investigating the potential of molecular biology tools to make this process more efficient. Molecular markers are also being used to increase our understanding of the pecan and muscadine genomes and the genetic diversity of cultivar populations

I am the Research, Extension, and Instruction (REI) Coordinator for the Horticulture Department at the Tifton campus.


Research Areas of Interest

  • Using biparental mapping and GWAS analysis to better understand the genetic control of horticulturally important traits in pecan and muscadine.
  • Broadening the germplasm pool of muscadine by evaluating and incorporating native vines into the breeding program.
  • Understanding the diversity of aroma volatiles in muscadine germplasm and how they might be manipulated to produce cultivars suited to the fresh-market and wine industries.
  • Development of pecan cultivars with reduced tree size.
  • Evaluation of existing pecan cultivars and germplasm for disease and insect resistance as well as nut quality and tree productivity.

Pecans and muscadines share many interesting features. Both are among the few native North American crops. Pecans are native to the lower Mississippi river and itsĀ tributaries, and muscadines are native to the southeastern U.S. Both have been recently domesticated and current cultivars are only a few generations removed from wild populations. While pecans and muscadines play an important role in the horticulture of the southern U.S., they have not received nearly as much research attention as traditional fruit crops such as apples and peaches. These crops have much untapped genetic diversity which should allow the breeding programs to advance quickly.
