In Brazil, sacha inchi oil is produced by hand from plant materials with no breeding or detailed information about the chemical composition of seeds. In addition, most of the current information on the agronomic traits of this species originates from research carried out in the Peruvian Amazon. In order to promote the research and cultivation of sacha inchi in the Brazilian territory, this study aimed to analyze, in the central Amazon region, different accessions of this oilseed for characteristics of production and quality of fruits and seeds, as well as to estimate genetic parameters, through mixed models, with identification of superior accessions, for breeding purposes. A total of 37 non-domesticated accessions were evaluated in a randomized block design, with five replications and two plants per plot. The average oil content in seeds was 29.07 % and unsaturated fatty acids amounted to 91.5 % of the total fat content. For the yield traits, the estimates of individual broad-sense heritability were moderate (~0.33), while the heritability based on the average of progenies resulted in a selective accuracy of approximately 0.85. The use of the selection index provided simultaneous gains for yield traits (> 40 %) and oil yield. A high genetic variability was observed for the main traits of commercial interest for the species, as well as promising perspectives for the development of superior varieties for agro-industrial use.

“…Its seeds have high agro-industrial potential due their elevated content of fatty acids, such as α-linolenic acid (omega-3) and linoleic acid (omega-6) (Follegatti-Romero et al, 2009). The species also has desirable features for reforestation and slope protection and it is appointed as an alternative to the recovery of degraded areas and to family farming programs (Bordignon et al, 2012). Although studies for in vitro propagation of sacha inchi can be found (Bordignon et al, 2012;Rodrigues et al, 2014), information about seed germination and seedling growth is incipient (Rosa and Quijada, 2013).…”

2 Investigador en manejo de cultivos tropicales, elaboración y aplicación de abonos orgánicos. RESUMEN Se evaluó el efecto de dos tutores y cinco tipos de biofertilizantes en el crecimiento y desarrollo de Plukenetia volubilis L. sacha inchi en un suelo de baja fertilidad. La plantación se estableció utilizando el diseño de bloques completos al azar en parcelas divididas, siendo las parcelas principales dos sistemas de tutor y las sub parcelas cinco tipos de biofertilizantes. Los cinco biofertilizantes fueron: Biol, Biol mas frutos de Solanum torvum, Biol más hojas de Carica papaya, Biol más hojas de Cymbopogon citratus y Biol más hojas de Chondrodendron tomentosum, más un testigo (SB) por cada sistema de tutor, teniendo un total de-1 doce tratamientos y tres bloques. Las dosis de aplicación fueron de 15 L.ha , divididas en aplicaciones-1 quincenales a razón de 1.5 L.ha en campo definitivo, las evaluaciones fueron realizadas cada quince días durante 5 meses. Los resultados indican que con los tratamientos T4 y T8 se redujeron los días para la fructificación, lográndose el mayor número de frutos con los tratamientos T4, T9 y T10, mejorando la productividad de plantas de P. volubilis L. ABSTRACT The objective was to evaluate the effect of two tutors and five types of biofertilizers on growth and development of Plukenetia volubilis L. in a soil of low fertility. The plantation was established using design randomized complete block split plot, with the two sets of main plots and sub plots tutor five types of biofertilizers. Biofertilizer five were: Biol, Biol more fruits of Solanum torvum, Biol more Carica papaya leaves, Biol more Cymbopogon citratus sheets of and Biol more Chondrodendron tomentosum sheets, and a control (SB) for each tutor system, having a total twelve treatments and three blocks. The application rate was-1-1 15 l.ha , divided into fortnightly applications by 1.5 l.ha final field evaluations were performed every two weeks for 5 months. The results indicate that the T4 and T8 treatments reduced fruit set days and the highest number of fruits per plant was achieved with T4, T9 and T10 treatments, improving the productivity of plants of P. volubilis L.

“…While the above properties of sacha inchi indicate it as an excellent food supplement, the species also has desirable characteristics for reforestation and slope protection and is an interesting option for family agriculture programs (Bordignon et al 2012). Although the composition and properties of sacha inchi are relatively well-known and its cultivation has already expanded to the regions of Alto Solimões and Manaus in the Brazilian Amazon, as well as to São Paulo State in southeastern Brazil (Rodrigues et al 2014), the available literature provides little information to facilitate the identification of superior genotypes.…”

Repeatability of biometric and fruit and seed yield traits of sacha inchi

Repeatability allows an estimation of the number of evaluations needed to optimize the selection of superior genotypes, with consequent effects on the research costs in terms of financial and human resources. The objective of this study was to estimate the coefficient of repeatability of biometric and yield traits, related to fruits and seeds of sacha inchi (Plukenetia volubilis), and to define the number of evaluations required for an efficient selection and evaluation of genotypes of the species. A total of 37 non-domesticated accessions were evaluated for 19 months in a randomized block design with 5 replications and 2 plants per plot. The total number of fruits, total number of seeds, total fruit weight, mean fruit weight, and number of seeds per fruit of the accessions were evaluated by monthly sampling. Additionally, seed biometry was assessed in a sample of 30 seeds per accession. Repeatability coefficients were estimated by analysis of variance, principal components and structural analysis. The principal component method based on the covariance matrix was the most appropriate for establishing repeatability estimates of sacha inchi, due to the cyclical nature of the crop. Superior genotypes of the species can be selected for yield-related traits with about 90% accuracy, from 5 harvests (months) onwards. To ensure this accuracy level, it would be necessary to evaluate a minimum of 5 and 25 fruits to determine mean fruit weight and number of seeds per fruit, respectively, and 39 seeds would be required to evaluate the biometric traits.
