Research Project: ENHANCEMENT OF COLD TOLERANCE IN SORGHUMS Project Number: 6208-21000-017-16
Project Type: General Cooperative Agreement

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

Objective:
1. To characterize selected germplasm lines of sorghum for response to cold stress at early season and at other specified stages of development and accelerate the development of improved germplasm resources for different types of sorghums. 2. To investigate the genetic and physiological basis of cold tolerance in sorghums through genetic studies of tannin genes in sorghum.

Approach:
1. Establish replicated field trial of sorghum lines in various locations to estimate genotype by environment interaction. 2. Perform fine mapping of two QTLs in the population of 109 F6:7 RILS developed from Tx430/SQR, and in two additional mapping population Tx430/SC1103 and Tx430/SC1345, each with 250 F6:7 RILS and characterize, phenotypically and genotypically the 300-line sorghum diversity panel for testa layer.
