FloRun™ '331' Peanut Variety

Barry L. Tillman

FloRun™ '331' peanut variety was developed by the University of Florida Institute of Food and Agricultural Sciences, North Florida Research and Education Center near Marianna, Florida. It was released in 2016 because it combines high yield potential with excellent disease tolerance. FloRun™ '331' has a typical runner growth habit with a semi-prominent central stem and medium-green foliage. It has medium runner seed size with high oleic oil chemistry.

Under irrigated conditions in Florida, it reaches optimum maturity about 140 days after planting or around 2500 adjusted growing degree days. As described below, FloRun™ '331' has demonstrated high yield potential under both irrigated and non-irrigated conditions. In four years of testing in Florida, the irrigated yield of FloRun™ '331' was similar to that of Georgia-06G, TUFRunner™ '297', and Georgia-12Y (Table 1). However, in non-irrigated tests over four years, its yield was about 400 pounds per acre higher than these control cultivars (Table 2). These results demonstrate the great yield potential of FloRun™ '331' in Florida. Results are also available for its performance in 2017 in Georgia (Mailhot et al. 2018) and Mississippi (Burgess et al. 2018). In Georgia, pod yield of FloRun™ '331' ranked within the top nine entries (9, 4, and 3 out of 22) in three irrigated tests. In non-irrigated tests in Georgia, it ranked twelfth in Tifton, GA, fourth in Plains, GA, and first in Midville, GA. In Mississippi, FloRun™ '331' ranked second in pod yield across three locations in 2017.

The seed size of FloRun™ '331' is smaller than that of Georgia-06G. The sound mature kernels (SMK) of FloRun™ '331' contained 660 seeds per pound, whereas the SMK of Georiga-06G had 590 seeds per pound (P>F<0.001). Since peanut seed are sold by the pound, not by seed count, this will mean that the seed cost of FloRun™ '331' is lower than Georiga-06G and other large-seeded cultivars when planting the same seeding density.

FloRun™ '331' has demonstrated very good resistance/tolerance to leaf spot and white mold. Table 3 shows the performance of FloRun™ '331' in white mold tests, with yields of over 4,000 pounds per acre under severe white mold pressure and over 6,000 pounds per acre with minimal white mold pressure. Likewise, FloRun™ '331' has performed well in the presence of late leaf spot. Table 4 shows the performance of FloRun™ '331' under three leaf spot spray programs. Even when it was not sprayed for the entire season, it yielded over 3,000 pounds per acre. FloRun™ '331' has moderate resistance to tomato spotted wilt as indicated in the 2018 Version of the Peanut Disease Risk Index (Kemerait et al. 2019). In that publication, FloRun™ '331' has 15 points for TSWV compared to 10 points for Georgia-06G and 20 points for Georgia-09B.

In summary, FloRun™ '331' has demonstrated an outstanding combination of yield potential, grade, and disease tolerance, all of which makes it well adapted to the southeastern United States peanut production regions. In addition to these important characteristics, it has high oleic oil chemistry, which provides extended shelf life of roasted peanuts and peanut products and may command a premium price at the buying point.
