The papaya crop occupies 32 thousand hectares of planted area in Brazil, with a total
annual production of 1.6 million tons (12.5% of the world supply). The country stands out in …

Diallel crossing methods provide information regarding the performance of genitors between
themselves and their hybrid combinations. However, with a large number of parents, the …

The absence of cultivars with satisfactory levels of genetic resistance justifies the search for
genotypes incorporating disease-resistance genes in the papaya-breeding program. In this …

In support of breeding of papaya (Carica papaya), the disease incidence and severity of
powdery mildew (Ovulariopsis caricicola) were evaluated in papaya genotypes. Two …

Genótipos crioulos são importantes fontes de genes de adaptação, rusticidade e resistência
de plantas a doenças bióticas e a estresse ambiental. Avaliou-se neste trabalho o potencial …

Variedades crioulas constituem alternativas para a ampliação da base genética e

A resistência genética constitui alternativa sustentável para o controle da mancha-de-
phoma na cultura do mamoeiro. No entanto, estudos básicos são necessários para a …

This study aimed to analyze the genetic variability and to estimate diversity parameters of 23
elite papaya lines based on microsatellite molecular markers. The plant material was …

In order to select superior hybrids for the concentration of favorable alleles for resistance to
papaya black spot, powdery mildew and phoma spot, 67 hybrids were evaluated in two …

In this work, two experiments were set up in order to select papaya hybrids and verify
heterosis expression for black spot (Asperisporium caricae) and phoma spot …
