Research Project: The Development of Breeding Populations in Cotton Through Random Mating

Location: Genetics and Sustainable Agriculture Research Unit

2010 Annual Report

1a.Objectives (from AD-416)
Linkage disequilibrium study on parents and C5 cycles of random mating using molecular markers. Marker data on parental lines have been completed. Development of recombinant inbred lines from half-sib families in the random mating.

1b.Approach (from AD-416)
Winter nursery will be utilized to increase seed of RIL to produce about one pound of selfed seed from each half-sib family. Seed will be planted for agronomic and fiber performance in a field environment.

3.Progress Report

We developed 550 recombinant inbred lines from a random mated population of 11 cultivars. Seed were increased and planted in the field. Leaf samples were collected for simple sequence repeat (SSR) markers analysis. This project was monitored by phone conversations and by two meetings during the year. Quarterly reports were sent to Cotton Incorporated since this is a reimbursable agreement.
