| The phenotypic diversity of sweet potato (Ipomoea batatas) landraces was assessed using morphological traits, verifying how this diversity is distributed among the households and settlements of the Vale do Ribeira, Brazil. A total of 74 accessions, involving 53 landraces, collected from 30 households distributed among 18 settlements that practice traditional agriculture in the municipalities of Iguape, Ilha Comprida, and Cananeia, as well as four commercial varieties acquired in markets of Iguape and Piracicaba, were evaluated under an ex situ experimental condition in Piracicaba, SP, Brazil. Nine phenological and floral descriptors, nine morphological vegetative aerial descriptors and five storage root traits were recorded. The 14 aerial vegetative and... |

| ABSTRACT: Pea (Pisum sativum L.) is the fourth leading legume crop in the world, and its demand is increasing. In this study, the morphological characteristics (seed shape, seed surface, seed coat color, hilum color, cotyledon color, 100-seed weight and color values), total phenolic content (TPC), total flavonoid content (TFC), 2,2’-azinobis-(3-ethylbenzthiazoline-6-sulphonate) (ABTS) free radical scavenging capacity and ferric reducing antioxidant power (FRAP) of 75 pea cultivars were investigated. Results showed rich genetic diversity and a wide range of phenolic contents and antioxidant activities. Sixteen varieties enriched with phenolic contents and high antioxidant activities were screened out. A significant correlation was reported among color... |

| ABSTRACT In a collection of costeño peppers conserved by indigenous producers from the municipalities of Santa Maria Tonameca and Santo Domingo de Morelos, Oaxaca, Mexico, a description and classification of agromorphological variation was undertaken by characterization of 46 populations in a greenhouse distributed under complete randomized block design with three replicates. Days to first flowering, plant and fruit traits and yield per plant were evaluated. Significant differences were detected for all traits except for plant height at 120 days after planting. In a principal component analysis, the variables of green and dry weight of 15 fruits, average fruit weight, number of fruits and yield per plant were the characteristics with major descriptive... |
