Research Project: SIMULTANEOUS IMPROVEMENT OF FIBER QUALITY AND HEAT TOLERANCE

Location: Plant Stress and Germplasm Development Research

Project Number: 6208-21000-018-11
Project Type: Reimbursable

Start Date: Jan 01, 2012
End Date: Dec 31, 2012

Objective:
The research proposed for 2012 will focus on cotton reproductive stress tolerance and the further development and characterization of recombinant inbred populations of PHY72(F) X STV474(M) and STV474(F) X PHY72(M). The proposed research will focus on understanding the genetic control of cotton pollen dehydration tolerance and the underlying biochemical reasons for observed differences in stress tolerance.

Approach:
The PHY72(F) X STV474(M) and STV474(F) X PHY72(M)recombinant populations will be advanced to the F7 generation. Flower shape and pollen dehydration tolerance will be re-evaluated on F7 plants. DNA will be harvested and sent to the USDA-ARS Cotton Fiber Bioscience Research Unit, New Orleans, LA, for mapping studies. Lint samples will be harvested and sent to CI for quality evaluation. If we are able to obtain sufficient seed, we will plant the population in the field for initial yield evaluations.
