Multilocation Evaluation of Virginia and Runner -Type Peanut Cultivars for Yield and Grade in Virginia–Carolina Region

The peanut is mostly grown in semi-arid tropical regions of the world, characterized by unpredictable rainfall amounts and distribution. Average annual precipitation Virginia–Carolina (VC) region around 1300 mm; however, distribution can result significant periods water deficit subsequent reduction yield gross income. development new cultivars with high acceptable levels stability across various water-availability scenarios an important component breeding program Virginia Carolinas, where large-seeded Virginia-type predominantly market type. In addition, simultaneous use runner developed dryer southeastern has been proposed as a practical solution to limited irrigation availability VC region. Still, identification adequate utilization available commercial best combination yield, drought tolerance, income more immediately beneficial industry, yet this assessment not carried out date. aim study was identify that maintain grade, therefore income, wide range environmental conditions. We evaluated five commercially runner-type for pod using multilocation trials over four years 13 environments. Additive main effects multiplicative interaction (AMMI) different approaches were used genotype (G), environment (E), their (G × E) on yield. Pod specifically assessed Lin Binn approach, Wricke’s ecovalence, Shukla’s stability, Finlay–Wilkinson approach. combined analysis variance showed highly (p ≤ 0.001) genotypes, environments, G E environments varied (2840–8020 kg/ha). Bailey, Sullivan, Wynne are cultivars. grade factors SMK, SS, TK changed regime within both types. Among cultivars, TUFRunner 297 presented mean productivity; it specific adaptation Based approaches, concludes Sullivan Bailey most stable adaptable testing whereas exhibited adaptability some These findings have implications cultivar recommendations terms meeting industry standards grading quality, progress.
