SILVA, Samuel Inocêncio Alves da; SOUZA, Tancredo; SANTOS, Djail  y  SOUZA, Renato Francisco da Silva. Evaluation of yield components in lima bean landraces grown in the Agreste region of Paraiba. Rev. de Ciências Agrárias [online]. 2019, vol.42, n.3, pp.151-160. ISSN 0871-018X.  https://doi.org/10.19084/rca.16956.

The aims of this study were: (i) to evaluate the yield of lima bean landraces; (ii) to determine the dissimilarities among landraces of lima bean; and (iii) to assess linear correlations among the yield components of lima bean landraces grown on sandy soils of the Brazilian semi-arid. A field experiment was carried out using a randomized block design with eighteen treatments (nine lima bean landraces vs. two years of cultivation) with four blocks. We evaluated pod length and width, pods.plant^-1, seeds.pod^-1, one-hundred seed weight and yield. Cara Larga, Eucalipto, Rosinha and Roxinha landraces presented the highest values of pods.plant^-1. Orelha de Vó presented the highest one-hundred seed weight and yield. Negative correlations were found between one-hundred seed weight, pod.plant^-1 and seeds.pod^-1. The yield components seeds.pod^-1, one-hundred seed weight and pods.plant^-1 are useful components to estimate yield of lima bean landraces.
