Abstract
ABSTRACT: The peach palm (Bactris gasipaes) is a palm tree that produces palm heart originated of Amazonia with economic, social and environmental sustainability. To obtain improved cultivars it is necessary the evaluation and selection of genotypes with characteristics that support producers, manufacturing and consumers. In this context, the objective of this study was to estimate genetic parameters for palm heart production traits of peach palm considering half sibs progenies. Twenty progenies of Putumayo macrocarpa race were evaluated in seven cultivation cycles. The experiment was designed in complete randomized blocks, with 40 repetitions and one plant per plot. The genetic parameters were estimated by REML/BLUP methodology. Low genetic variability was observed in the population, possibly due to the narrow genetic base from original population. However, considering the significant genetic effect and the progeny mean heritability, the selection performed between progenies is more efficient than individual selection. The high number of measurements required for most of the evaluated characters becomes impractical in peach palm breeding programs. The number of palm heart per plant can be used to perform indirect selection for total production of palm heart.
Highlights
Recognition of a global market for palm heart and the availability of techniques for planting, handling and processing of peach palm (Bactris gasipaes Kunth) for palm heart, has generated a great increase in its cultivation and studies since 1990 (CLEMENT & BOVI, 2000)
According to MORA URPI & CLEMENT (1988) and SOUSA et al (2001), the peach palm was subdivided into primitive races formed by individuals that possess a set of morphological and functional characteristics transmitted by inheritance, and which were created by the first peoples of Received 08.08.18
The average of palm heart total mass per hectare (PT) obtained is considered high (3,412 kg ha-1 year-1), being higher than the averages observed in the coast of São Paulo, by BOVI et al (2004), which obtained less than 2,000 kg ha-1 with limestone application in the production area
Summary
Recognition of a global market for palm heart and the availability of techniques for planting, handling and processing of peach palm (Bactris gasipaes Kunth) for palm heart, has generated a great increase in its cultivation and studies since 1990 (CLEMENT & BOVI, 2000). V.49, n.7, Amazon in thousands of years of domestication According to these authors, in Brazil, along the Solimões and Amazon Rivers, three primitive breeds were proposed, using as main criterion of segregation fruts size. One of these is the Putumayo (macrocarpa) race, located along the upper Solimões River and adjacent areas in Colombia and Peru, which has large, starchy fruits
