Narrative
The ICGV-SM 86715 (♀) and Serenut 2 (♂) cross was done at National Semi Arid Resources Research Institute (NaSARRI) Serere to improve ICGV-SM 86715 for seed size, sweetness, Groundnut rosette disease resistance, drought, maturity (early). Test for hybridity was done in F1 plants. Selected F3 plants shuttle tested for GRD resistance at Nakabango and Serere two known hotspots for Groundnut rosette disease (GRD) and Late leafspots (LLS). Special attention was put for any transgressive segregation towards to wild type (chacoense) phenotype. As the early segregation materials were being advanced in the observation nursery via combined pedigree and single seed descent, wild type phenotypes were observed in two F5 plants. These two plants (one red and one tan seeded) were row planted in F6 and the tan one gave rise to NARONUT 2T. Naronut 2T has a decumbent 3 growth habit (l), alternate branching, and medium-sized elliptic green leaves. They have, on average, seven primary and four secondary branches. It matures in 75-85days, depending on the season and location in Uganda. It has medium-sized pods (34.7 mm average length, 11.2 mm average width) with prominent reticulation, moderate beak, and moderate to deep prominent constriction. Roots are extensive and long and reticulated pods holds soil. The majority of pods are two or one-seeded (occasionally, three-seeded), with average meat content of 64%. Naronut 2T seeds are oblong, tan, sweet (4.0/6.0), weigh 57 g (100 seed), are 25.74% protein, and contain 39.58 % fat. Naronut 2T has a distinct white seed bed/cushion in the inner pod where the seeds sit. Its pegs are very strong even at maturity, making them easy to hand harvest and pods are soft and easy to shell.

Pedigree
Description:
Naronut 2T was selected from a cross between ICRISAT lines ICGV-SM 86715 and Serenut 2 (ICGV-SM 90704). ICGV-SM 86715 was derived from a cross between Makulu Red and a tetraploid interspecific backcross derivative [(Samaru 38 x Arachis chacoense) x Samaru 61] and has resistance to early and late leafspot diseases and rust. Serenut 2 is a derivative of a cross between RG-1 and ManiPintar. Serenut 2 is drought tolerant with resistance to Groundnut rosette disease and leafspot diseases.
