BRS Boitatá and BRS Ocauçu cassava cultivars for the industry have high root and starch yields and high starch contents in first-cycle and second- cycle harvests, medium tolerance to the main diseases, adequate architecture for mechanized planting and stability in starch contents.

RESUMO O objetivo do estudo foi caracterizar morfoagronômicamente 17 genótipos de mangueira, em relação à resistência à antracnose. O trabalho foi desenvolvido em campo e as avaliações foram realizadas por dois avaliadores em dois lados da planta, com amostragem aleatorizada. A severidade&#x...

A espécie de maracujá Passiflora bahiensis Klotzsch é endêmica do Nordeste do Brasil, encontrada nos Estados da Bahia e Pernambuco, sendo que na Bahia foi encontrada em área de Mata Atlântica, e floresce e frutifica de setembro a maio (Nunes; Queiroz, 2006; Bernacci et al.,&#x...

Cassava (Manihot esculenta Crantz) starch consists of amylopectin and amylose, with its properties determined by the proportion of these two polymers. Waxy starches contain at least 95% amylopectin. In the food industry, waxy starches are advantageous, with pastes that are more stable t...

Cassava (Manihot esculenta Crantz) holds significant importance as one of the world's key starchy crop species. This study aimed to develop core collections by utilizing both phenotypic data (15 quantitative and 33 qualitative descriptors) and genotypic data (20,023 single-nucleotide polymorphisms...

Despite the economic and social importance, high-yielding cassava cultivars are only released after extensive research, mainly due to the low multiplication rate. This study aimed to assess the impact of using smaller-sized seed cuttings treated with agrochemicals (8MP) compared to the conve...

Thematic collections (TCs), which are composed of genotypes with superior agronomic traits and reduced size, offer valuable opportunities for parental selection in plant breeding programs. Three TCs were created to focus on crucial attributes: root yield (CC_Yield), pest and disease resistance&#x...

Genotype-environment interaction (GEI) presents challenges when aiming to select optimal cassava genotypes, often due to biased genetic estimates. Various strategies have been proposed to address the need for simultaneous improvements in multiple traits, while accounting for performance and yield stab...

In the state of Amazonas, the ‘Pêra’ orange scion is traditionally cultivated on ‘Rangpur’ lime tree. The restricted use of a single scion-rootstock combination has left local orchards vulnerable to adverse conditions and incidence of pests and diseases, which may negatively interfere w...
