چکیده
ABSTRACT Cowpea (Vigna unguiculata (L.) Walp.) is an excellent crop for research in semi-arid regions, due to its tolerance high temperatures and water deficit, with satisfactory yields rain-fed cultivation. The objective this work was evaluate the genotype x environment (G × E) interaction, adaptability stability of cowpea landraces used Cariri, Paraíba, semiarid region Northeast Brazil. experiment carried out under conditions two locations region. For all traits evaluated, G E interaction simple, which means that evaluated can be recommended different environments tested. results also suggest phenotypic selection efficient enhance yield and, therefore, practiced by farmers themselves. most advantageous were ranked good (qi <5%). Although performance standards between similar environments, best values obtained on farm environmental conservation history higher precipitation. Therefore, integration landraces, agricultural landscapes, strategic planning considers possible variations local precipitation essential models sustainable development zones

Stability Analysis of Genotype × Environment Interaction Effect on Sugar Yield in Sugar Beet Hybrids
Testing plant varieties under different regions is necessary to assess their stability. In this study, 17 sugar beet genotypes were evaluated in a randomized complete block design with six replications in five regions including Karaj, Hamedan, Miandoab, Mashhad, and Shiraz. After checking the homogeneity of mean squares in five experiments by Bartlett’s test, analysis of the combined was per...
