Narrative
TifGP-3 and TifGP-4 are both runner market-type in seed and pod size with a spreading growth habit. They both have a very high level of resistance to late leaf spot. TifGP-3 and TifGP-4 exhibited a high level of resistance when evaluated in field trials for two years. This resistance has also been documented in in vitro detached leaf studies. Similar to field results, TifGP-3 and TifGP-4 produced significantly fewer LLS lesions 20 days after inoculation in comparison to susceptible lines. TifGP-3 and TifGP-4 also exhibited significantly lower % sporulating lesions and smaller lesion area in comparison to a susceptible check. TifGP-3 has introgressed segments from A. cardenasii on the top of chromosome A02, the bottom of A02 and the bottom of A03. TifGP-4 has the introgressed segments on the top of A02 and the bottom of A03. The level of resistance to LLS observed in these two lines was not significantly different. Segments on the top of A02 combined with the bottom of A03 accounted for the majority of LLS resistance. Some breeders may choose to use TifGP-4 to minimize the chance of linkage drag. However, important traits may exist in the segment on the bottom of A02 so we are also releasing TifGP-3.

Pedigree
Description:
An F2 population was developed by crossing TifNV-High O/L x IAC 322. The F2 population consisted of 392 individuals and was genotyped by KASPar assays and selected for presence or absence of the A. cardenasii segments on chromosomes A02 and A03. TifGP-3 has introgressed segments from A. cardenasii on the top of chromosome A02, the bottom of A02 and the bottom of A03. TifGP-4 has the introgressed segments on the top of A02 and the bottom of A03.
