El objetivo de este estudio fue caracterizar las heladas meteorológicas, agronómicas y el impacto en el cultivo de alfalfa (Medicago Sativa L.) para la región Puno, mediante un análisis físico-estadístico de la información obtenida a partir de observaciones diarias de las temperaturas mínimas, máximas y precipitación pluvial provenientes de una red de 18 estaciones meteorológicas de un período de 17 años (1996/2013). El análisis de los datos de las estaciones meteorológicas agrupados con la técnica de análisis de conglomerados, produjo tres clústeres, determinándose la frecuencia anual y por período de heladas meteorológicas; la fecha promedio de ocurrencia de primera y última helada; y la duración del período libre de heladas tanto para heladas meteorológicas como agronómicas. La caracterización de las heladas indica una estrecha relación de la temperatura y ...

Background Loche (Cucurbita moschata) is a pre-Columbian squash that is cultivated exclusively in the northern coast of Peru, Lambayeque. This crop is notable for the presence of warts in its skin and for its vegetative reproduction as it commonly lacks of seeds in fruits. Currently, loche may be considered a new product for international markets, recognizing the gastronomy of Lambayeque in the world and dynamizing the Peruvian agro-export area. However, genomic information about this squash is very limited.

The Arnaucho chili pepper (ACP) is a traditional vegetable used in Peru because of its gastronomic properties. Due to its importance in the Peruvian diet and economy, this species is a resource that can be a candidate to plant breeding programs. In this study, the complete genome nucleotide sequence of this chili pepper was generated using the Illumina Hiseq 2500 sequencing technology. We sequenced the whole genome of the ACP using a paired-end 150 strategy, obtaining 330.46 GB of sequencing data. The genome size of the ACP was 2.98 Gb with a contig N50 of 237 Mb and 95.39% complete BUSCOs. Also, we identified 71.96% of repetitive DNA of the genome assembly, of which retroelements occupy 37.95% of the total genome. We downloaded genomes of the Solanoideae subfamily and conducted a comparative analysis of simple sequence repeats (SSRs) with our draft genome, and we identified lower number...
