“…Similar levels of polymorphism associated with RAPD markers have been reported in earlier studies involving mango (Rahman et al, 2007;Anju et al, 2008;Rajwana et al, 2008). According to Faleiro et al (2009), the number and percentage of polymorphism in RAPD fragments depend on the number and variability of the cultivars and/or accessions analyzed. Based on the results established herein, the variability present in the germplasm bank of Embrapa Meio-Norte must be considered significant.…”

“…There are numerous examples of the application of molecular markers in the analysis of the genetic diversity of mango (Viruel et al, 2005;Pandit et al, 2007;Santos et al, 2008;Singh and Bhat, 2009;Gálvez-López et al, 2009;Singh et al, 2010), several of which have employed the RAPD technique (Karihaloo et al, 2003;Ravishankar et al, 2004;Souza and Lima, 2004;Srivastava et al, 2004;Rajwana et al, 2008;Faleiro et al, 2009). RAPD markers have also been utilized in identifying genitors of open-pollinated mango hybrids generated by the Embrapa Cerrados Plant Improvement Program (Cordeiro et al, 2006a), and in determining the genetic origin of plantlets from polyembryonic mango seeds of cultivar Rosinha (Cor-deiro et al, 2006b).…”

ABSTRACT. We evaluated genetic variability of mango (Mangifera indica) accessions maintained in the Active Germplasm Bank of Embrapa Meio-Norte in Teresina, Piauí, Brazil, using RAPDs. Among these accessions, 35 originated from plantings in Brazil, six from the USA and one from India. Genomic DNA, extracted from leaf material using a commercial purification kit, was subjected to PCR with the primers A01, A09, G03, G10, N05, and M16. Fifty-five polymorphic loci were identified, with mean of 9.16 ± 3.31 bands per primer and 100% polymorphism. Application of unweighted pair group method using arithmetic average cluster analysis demonstrated five genotypic groups among the accessions examined. The genotypes Rosa 41, Rosa 48 and Rosa 49 were highly similar (94% similarity), whereas genotypes Sensation and Rosa 18 were the most divergent (only 7% similarity). The mango accessions were found to have considerable genetic variability, RAPD analysis of the genetic diversity of mango germplasm demonstrating the importance of analyzing each genotype in a collection in order to efficiently maintain the germplasm collection.

“…To this date there are few cultivars of pitayas registered with the Ministry of Agriculture, Livestock and Food Supply (MAPA), recommended for commercial planting in Brazil (FALEIRO et al, 2021;. In order to make available to rural producers more adapted to Brazilian soil and climate conditions genotypes of pitaya, a genetic breeding program carried out at Embrapa Cerrados developed five superior pitaya genotypes of different species.…”

The Embrapa Cerrados pitaya breeding program developed five superior genotypes of different species. The objective of this work was to evaluate the yield capacity of these five pitaya genotypes under the edaphoclimatic conditions of the Federal District. The experiment was carried out at the Embrapa Cerrados in Planaltina, DF. The five selected pitaya genotypes were evaluated, as well as a parent genotype used in the breeding program. Length (CF), diameter (DF) and mass (MF) of all fruits were evaluated, as well as the length/diameter ratio (CF.DF-1), number of fruits per plant (NF.PL-1), production per plant (kg.PL-1) and estimated productivity (t.ha-1). BRS Luz do Cerrado and BRS Lua do Cerrado presented larger and heavier fruits, while BRS Minipitaya do Cerrado presented the smallest fruits. CPAC Roxa and BRS Granada do Cerrado presented more rounded fruits. BRS Granada do Cerrado had the highest yield capacity in the two evaluated crops. The results obtained prove the importance of genetic breeding and the selection of superior genotypes more adapted to the region of cultivation, in order to guarantee greater profitability and products of better quality to rural producers and consumers.
