Narrative
TifGP-2 is runner market-type in seed and pod size. It has a spreading runner growth habit with an erect mainstem that is prominent throughout the growing season, and at harvest. It is a medium maturity class peanut, with about 135 days needed for optimal maturity. TifGP-2 has a tan testa (seed coat) with percent meat comparable to other runner cultivars. TifGP-2 is most similar to the cultivar, Tifguard. Tifguard is resistant to the peanut root-knot nematode, and this resistance is the result of a single dominant gene contained within an introgression on chromosome 9A. This introgressed chromosome segment is large, spanning one-third to one-half of chromosome 9A, which may result in yield drag. These late generation sister line with (Tifguard) and without (TifGP-2) nematode resistance can be valuable research tools to obtain a better understanding of the interaction of nematodes with other pathogens of peanut.

Pedigree
Description:
TifGP-2 originated from a cross of C-99R and COAN.. The original population was advanced to the F4 using single seed descent. Individual F4 plants were harvested and the population was subjected to selection pressure for yield, grade, and for resistance to the peanut root-knot nematode and tomato spotted wilt for the next three generations. Tifguard, a cultivar with resistance to the peanut root-knot nematode, was selected from this population. TifGP-2 was developed as a nematode susceptible F4 derived F5 sister line of Tifguard
