“…Results obtained for the different osmotic potentials reinforce the idea of the need to study the clustering of genotypes for a wide range of saline environments. According to Almeida et al (2011), similar results to those obtained in this study were found, where the grouping of genotypes of Vigna unguiculata was altered during plant development in different saline environments, due to the phenotypic responses varying greatly from one environment to another.…”

“…However, the lack of water reduces turgor pressure, thereby reducing the sap flow through the conducting vessels, causing retardation in cell elongation and plant production. According to Almeida et al (2011), the ability of plants to minimize the negative effects of salinity varies among genotypes, as also evidenced by Brito et al (2014) and Silva et al (2014), who studied citrus rootstock genotypes under saline conditions and confirmed the deleterious action of salinity on the citrus scion/rootstock combinations.…”

-In two simultaneous experiments, we evaluated the impact of brackish irrigation water and nitrogen (N) fertilization on the production of citrus (scion-rootstock combinations) and its associated gas exchanges. These experiments were conducted at the Campus of Federal University of Campina Grande, Brazil in a protected environment (shade screens on the sides) using drainage lysimeters. Experiment I used a randomized block design (3 replicates), in a 5 × 3 factorial arrangement, corresponding to five water salinity levels (0.6, 1.2, 1.8, 2. . For both experiments, gas exchanges and mean mass of fruits were evaluated at harvest. Gas exchanges were inhibited in plants under saline stress. Plants grafted with Common Rangpur lime showed greater production potential than did the other genotypes studied, even under brackish water conditions.

“…These clustering methods have been used in cowpea (OLIVEIRA et al, 2003;PASSOS et al, 2007, BERTINI et al, 2009, ALMEIDA et al, 2011, SANTOS et al, 2014 and they are intended to reduce the number of traits and consequently simplify the obtainment of genetic distances (CORREA; GONÇALVES, 2012). Given the above, this study aimed to characterize the genetic variability of agronomic traits and estimate the genetic divergence among cowpea genotypes by multivariate analysis.…”

Cowpea is a legume of great importance in the Brazilian nutrition, mainly in the Northeast region. Despite the low yield of Brazilian cowpea, the species presents a genetic potential to be explored. Thus, this work aimed to characterize the genetic diversity of cowpea genotypes by agronomic traits and select genotypes for possible crosses by multivariate analysis. Four value for cultivation and use tests were carried out with cowpea genotypes in 2005 and 2006, in the municipalities of Aquidauana, Chapadão do Sul, and Dourados, in the state of Mato Grosso do Sul. The experimental design was a complete randomized block with 20 genotypes and four replications. The evaluated traits were value for cultivation, plant lodging, pod length, grain weight of five pods, number of grains per pod, pod weight, severity of powdery mildew, and grain yield. To estimate the genetic diversity among the genotypes, the optimization methods of Tocher and UPGMA were used. The generalized distance of Mahalanobis was used as a dissimilarity measure. The clustering methods revealed genetic variability among the cowpea genotypes evaluated. The methods used formed a different number of groups for each environment. Genotypes TE97-309G-24, MNC99-542F-5, BRS Paraguaçu, BRS Paraguaçu, BR 17-Gurguéia, and CNC x 409-11F-P2 can be used to obtain promising combinations and high genetic variability.
