SORGHUM.RIL.BTX623XIS3620C.POPULATION

 
Evaluation location: , United States
Phenotypic evaluation of the original 137 F2-derived F6-8 generation inbred lines from the BTx623/IS3620C population was conducted as early as 1994. The population was planted in a randomized complete block design with two replications in College Station, Texas (30.5°N, 96°W) and Lubbock, Texas (33.6°N, 101.9°W). The population was evaluated for 28 traits in both locations and QTL analyses for these traits were performed (Hart et al., 2001; Feltus et al., 2006). In 2004, 119 of the F7 to F9 RILs were cultivated and phenotyped in: College Station, Texas (30.5°N, 96°W), Halfway, Texas (34°N, 101.5°W), and Weslaco, Texas (26°N, 98°W). Utilizing these 119 F7 to F9 RILs, 15 agronomic traits including primary, secondary, and tertiary branching were measured and QTL analyses for these traits were performed by Brown et al. (2006). Laboratory studies were also conducted on a subset of the population at the USDA-ARS Plant Stress & Germplasm Development Unit in Lubbock, TX in 2004 and 2005 for seedling tolerance to chilling and high temperatures.
