Characterization and genetic diversity of Coffea canephora accessions in a germplasm bank in Espírito Santo, Brazil
نویسندگان
چکیده
The state of Espírito Santo is the major producer Coffea canephora in Brazil. Knowledge genetic reserves fundamental to plant breeding. Therefore, present study characterized and analyzed diversity 600 C. accessions from germplasm bank Incaper based on 38 traits evaluated 24-30-month-old plants. Further, predominant descriptors or were identified, high phenotypic variability was determined. Genetic distances for grouped (Gower), quantitative, qualitative datasets 0.48, 0.61, 0.92, respectively, with 76 (Conilon) 407 (Robusta) being most divergent ones at Incaper. In clustering using Tocher optimization method, 30 groups formed, three introduced Epamig’s Robusta collection dissimilar ones. Graphical dispersion analysis principal coordinate method revealed predominance formed by Robusta, Conilon, hybrid × Conilon genotypes.

Genetic variability in accessions of the acerola germplasm bank of Universidade Federal Rural de Pernambuco, Brazil.
Brazil is the world's largest producer of acerola, Malpighia emarginata (Malpighiaceae); the Northeast is responsible for 60% of the national production. The culture of acerola in Brazil has great genetic variability; plantings have high phenotypic diversity and are not very productive, often originating from propagation by seed. We evaluated the genetic diversity of 42 accessions from the Acer...
