Registration of FloRun ‘T61’ peanut

Abstract

FloRun ‘T61’ (Reg. no. CV-159, PI 700039) is a high-oleic, runner market-type peanut (Arachis hypogaea L. subsp. hypogaea var. hypogaea) cultivar developed by the University of Florida Agricultural Experiment Station, North Florida Research and Education Center, near Marianna, FL. It resulted from a cross between ‘Georiga-06G’ and a University of Florida Agricultural Experiment Station experimental line ‘UF12302’ and was tested under the experimental designation UF11 × 41-HO1-4-1-1 and was approved for release in 2021. FloRun ‘T61’ has a semi-prostrate growth habit, with moderate vine size and a prominent center stem. The seed is smaller than seed of Georgia-06G but larger than FloRun ‘331’ (67.3 g vs. 64.6 g; P < 0.0001). It yielded similarly to FloRun ‘331’ over the 4-year period of 2017–2020 in three Florida locations (7862 kg ha⁻¹ vs. 8068 kg ha⁻¹), and its pod yield was slightly greater than Georgia-06G during the 5-year period of 2016–2020 (7680 kg ha⁻¹ vs. 7273 kg ha⁻¹; P = 0.0137). The total sound mature kernel grade of FloRun ‘T61’ was slightly greater than that of FloRun ‘331’ (78.6% vs. 77.7%, P < 0.025) but was similar to the total sound mature kernel grade of Georgia-06G. FloRun ‘T61’ has high oleic oil chemistry composed of 77.1% oleic fatty acid versus 58.7% for Georgia-06G in 2020 (P < 0.001) and 79.2% in 2021 compared with 65.7% for Georgia-06G (P < 0.001). Over 5 years, the spotted wilt ratings of FloRun ‘T61’ (2.5) were less than for FloRun ‘331’ (4.8; P < 0.01). In summary, FloRun ‘T61’ combines excellent yield, grade, disease, and oil chemistry traits and should be beneficial to farmers and manufacturers of peanut foods.
