AGRO-MORPHOLOGICAL CHARACTERIZATION OF 16 TRADITIONAL PEPPER (CAPSICUM ANNUUM L.) CULTIVARS FROM CASTILLA-LA MANCHA (CENTRAL SPAIN)

Sixteen traditional pepper cultivars from Castilla-La Mancha (Central Spain) were morphologically characterized, focusing on aspects related to fruit and seeds.
A multivariate statistical analysis interpreted satisfactorily the information obtained in the characterization of the cultivars studied.
The Principal Component Analysis (PCA) resulted in the establishment of two well-differentiated groups, that of the accessions belonging to the Grossum group, with blocky shape (characterized by fruit with a large number of locules, width, wall thickness and weight, low dry matter content, and seeds with high weight and size), and the rest, that is, those not showing these characteristics.
An Analysis of Conglomerates corroborated the previous group and differentiated a second cluster which included the accessions of the Longum group, with elongated shape (characterized by fruits with a high dry matter content and a low number of locules, width, wall thickness and weight, seeds with a small weight and size, and, in minor measure, fruit longer and more lightness, and seeds with a lower percentage of germination compared to the previous group). There was an important positive correlation among fruit weight, width, wall thickness, number of locules and seed weight, and a high negative correlation between fruit dry matter and the previous fruit par¬ameters.
This work highlights the suitability of the multivariate statistical methods for analysis of data in this agronomic field.
