Abstract

’Serenut 5R’ (Reg. No. CV-129, PI 676092) is a new highyielding,
spanish-type groundnut (Arachis hypogaea L. subsp.
fastigiata var. vulgaris) with two seeds per pod. Serenut 5R was
released in 2010 by the National Semi-Arid Resources Research
Institute, Soroti, Uganda. It was a selection from the ICRISAT
advanced line ICGV-SM 93535. Serenut 5R originated from a
cross made between ICGM 522 and ‘RG 1’. ICGV-SM 93535 was
developed by using repeated bulk selections for groundnut
rosette disease resistance, using the infector row technique
at the ICRISAT-Malawi research station. Performance tests in
replicated trials were performed in Uganda in 2008 and 2009.
Trials were performed in two seasons each year and averaged
over 10 rainfed locations in Uganda. Serenut 5R matures
in 100 to 110 d, similar to the widely grown control cultivar
Serenut 3R. Serenut 5R resulted in significantly higher pod
yields (16%) than Serenut 3R, and the shellout percentage for
Serenut 5R was 4.8% higher than Serenut 3R. Seed testa is red,
and the seeds are slightly larger than those of Serenut 3R. The
sound mature kernel count for Serenut 5R was 38.7 g 100-1
compared with 32.38 g 100-1 for Serenut 3R, an increase of
19.51%. The dormancy period for Serenut 5R was significantly
less than Serenut 3R
