Research Project: Genetic Dissection of Heterotic Effects in Upland Cotton

Location: Coastal Plain Soil, Water and Plant Conservation Research

Project Number: 6082-21000-007-02-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Jan 1, 2013
End Date: Dec 31, 2013

Genetically characterize yield heterotic effects in an elite Upland x elite Upland cotton cross.

A population of approximately 200 Upland cotton, intraspecific recombinant inbred lines will be derived at the F5. Using a single replicate, augmented design, the recombinant inbred lines will be seed increased and phenotyped for agronomic and fiber quality performance. DNA will be extracted from each line and used to genotype the population. Each recombinant inbred line will be crossed to each parent following a NC Design III mating scheme. F1 seed will be harvested and seed increased at the Cotton Winter Nursery. To provide a pure seed source, each recombinant inbred line will also be self-pollinated and seed harvested.
