Genetic resources; Germplasm bank; ISSR; Manihot esculenta

Brazil is considered one of the domestication centers of cassava (Manihot esculenta), containing a large part of the biological diversity and traditional knowledge of the species. The aim of the present study was to evaluate the genetic diversity of cassava landraces grown by farmers in the north of Mato Grosso State, Brazil, using inter simple sequence repeat (ISSR) molecular ... more

Joint analysis; Random amplified polymorphic DNA markers; Solanum lycopersicum; Ward-MLM

Accessions in gene banks need to be characterized and evaluated to determine their genetic diversity. We made a joint diversity analysis of the tomato gene bank of the Universidade Estadual do Norte Fluminense Darcy Ribeiro in Rio de Janeiro state, using the Ward-modified location model. Forty Solanum lycopersicum accessions were characterized and evaluated for 22 morphoagronomic ... more

Genetic divergence; interspecific hybrid; Joint analysis; Morphoagronomic characterization; Ward-modified location model (MLM) method

Morphological characterization is the most accessible and used method to quantify the genetic diversity of the available germplasm. The multivariate statistical method is highly important for this purpose. This study aimed to characterize parents and hybrids of Passiflora according to morphoagronomic descriptors and estimate the genetic divergence between them based on the joint ... more

Coefficient of parentage; Genetic diversity; Germplasm characterization; Joint analysis; Sugarcane varieties

The success of the development of new sugarcane varieties is associated with the ability to correctly select the genitor. The aim of this study was to evaluate the genetic diversity between 113 clones and sugarcane varieties using the Ward-modified location model procedure with added information about the coefficient of parentage and endogamy. In this study, data was used from 100 ... more

Cassava; Linkage group; Manihot esculenta; Molecular genetic map; Physical localization; Primed in situ labeling

Physical localization of molecular markers and assign­ment of the 15th linkage group to chromosome 11 of the karyotype in cassava (Manihot esculenta Crantz) were achieved using primed in situ labeling. Amplified signals for both the EST507-1 and SSRY13-5 markers were consistently observed in different stages of cell division. A comparison of the length, arm ratio, and ... more

Cultured lymphocytes; Cytotoxicity; Genotoxicity; Manihot esculenta; Tucupi

The population of Pará (a state in Brazil) has a very characteristic food culture, as a majority of the carbohydrates consumed are obtained from cassava (Manihot esculenta Crantz) derivatives. Tucupi is the boiled juice of cassava roots that plays a major role in the culinary footprint of Pará. Before boiling, this juice is known as manipueira and contains linamarin, a toxic ... more

Leaf nutrients content; Manihot esculenta; Multivariate method; Nutritional status

Among the factors affecting cassava yield, the leaf nutrients content has received little attention since cassava genotypes may grow well under inappropriate nutrient supply, however showing inadequate nutritional quality of tuberous roots. Considering this aspect, the genetic diversity should be explored in order to determine standard leaf nutrients in cassava ... more

Genetic variability; Manihot esculenta; SSR

Cassava (Manihot esculenta) is a traditional crop in tropical and subtropical regions that is used for human consumption and in animal feed. This studied cassava landraces cultivated in northern Mato Grosso State, Brazil, to detect the variability in family farms, aiming at the preservation and use potential of these genetic resources. A total of 120 M ... more

Genetic variability; Manihot esculenta; SSR markers

Cassava is one of the main energy foods for millions of people, and has a great diversity of ethno-varieties that have specific characteristics often not found in commercial varieties. These constitute a gene pool and therefore a genetic resource that should be conserved and preserved. In this context, the objective of our study was to evaluate the genetic ... more

Genetic resources; Genetic variability; Germplasm; Orbignya phalerata

Babassu (Orbignya phalerata Martius) is one of the most important palms in Brazil because of the largest morphological variation, wide geographic distribution, and high socio-economic importance. The diversity present in babassu germplasm should be protected against loss to ensure their use with high productivity. Study of the available variability in populations of babassu is ... more
