AREA OF PRE-IMPROVEMENT, STATISTICS AND BIOMETRY

OUR AREA

We are responsible for the identification and generation of promising genotypes and populations to overcome biotic and abiotic stresses, as well as other attributes that allow the use of agrobiodiversity in the face of climate change.

FUNCTIONS

The following are functions of the Pre-Improvement, Statistics and Biometry Area:

  • To conduct and coordinate the evaluation and identification of promising accessions based on the morphological, agronomic and physicochemical characteristics of the agrobiodiversity species that are conserved ex situ and in situ.
  • To prepare the technical dossiers so that the promising accessions are utilized in genetic improvement programs and the development of new varieties.
  • To coordinate with curators and breeders to take advantage of the genetic diversity of identified and developed materials.
  • To support researchers in the design and analysis of experimental data.

RESEARCH TOPICS

The research topics of the area are:

LINE OF RESEARCH 1
  • Identification of promising accessions using biometric analysis methods and quantitative genetics.
LINE OF RESEARCH 2
  • Phenotype-genotype association that allows for the identification of regions of the genome associated with characteristics of interest in the agrobiodiversity conserved in the national germplasm bank of INIA and in in situ conditions.

CURRENT PROJECTS

Wild tomatoes are Solanaceae species that have as center of diversity the American continent. The exact location where the tomato domestication occurred has not yet been defined, but reports indicate that no domesticated varieties have been found domesticated in Peru but it is known that there is a great diversity of their wild relatives in our country. The conservation of these species is incipient in our country and much more with respect to its use in genetic improvement since we do not have native varieties or improved tomato varieties developed in Peru. However, we have a high diversity of wild species that could be used for the genetic improvement of new varieties adapted to local climatic conditions, pests and diseases.

This project aims to ensure the conservation of wild tomato species and improve their availability for genetic improvement. To achieve this, the collections of wild tomato germplasm conserved at INIA will be taxonomically characterized and the conserved accessions will be regenerated to increase the available seed population.
This project also includes the repair and conditioning of greenhouses, the purchase of equipment for cold storage of seeds and the strengthening of capacities through training of specialists in tomato taxonomy. Finally, the results of this work will be communicated through the elaboration of catalogues, updating of information in the information system of INIA (SIRGE-INIA) and at least one scientific publication.
