Abstract

PACHECO CH., César Andrés; VERGARA HOLGUIN, María Consuelo  and  LIGARRETO MORENO, Gustavo Adolfo. CLASSIFICATION OF 42 GENOTYPES OF PEA (PISUM SATIVUM L.) ACCORDING TO THE MORPHOLOGICAL CHARACTERS AND AGRONOMIC BEHAVIOR. Rev. Fac. Nac. Agron. Medellín [online]. 2010, vol.63, n.2, pp.5543-5553. ISSN 0304-2847.

The study was carried out in the Bogotá plateau (Colombia), under greenhouse conditions during two crop cycles. During the first cycle the morphological and agronomical variables associated with yield components, such us precocity, growth habit, number of branches, leaf type, leaf size, type and degree of curvature of pod, size of peduncle, number of pods per cluster, flower color and grain morphological characteristics were evaluated. In the second cycle, the disease “ascochyta” caused by Ascochyta spp. and Mycosphaerella spp was evaluated. The objective of this research was to identify pea lines prospective for plant breeding. The factorial analysis of mixed data (FAMD), allowed clustering 42 genotypes into 4 groups of qualitative and quantitative variation and also selecting the materials M-049, M-078, M-080 and M-082 as the best genotypes according to their agronomical characters.

Keywords : Genetic variability; plant breeding; mixed data.
