Abstract
Pea, Pisum sativum L., is the species that has the great agricultural importance within it is genus and it contains the major number of the varieties that are cultivated at present practically, it is an annual specie and at the same time it is an excellent vegetable that is cultivated by it is fresh seeds, ripe pods and by it is dry grains; besides because of all it is protein virtues. A conglomerate analysis was performed in order to classify the different pea genotypes addressed to ripe consumption, using the hierarchical Warts´s method. Taking into account this analysis the formation of four classes were derived, considering at a level of an Euclidean distance of 12,5.The research had made possible a classification into four classes, pointing out to the most important morphoagronomical characters for the cultivation (phenological characters, length of the stem and yield). The genotypes that has the major yield were grouped in class I and II, reaching values between 6,2 and 9,7 T x Ha-1 being the most prominent “Early Snap”, “Pea”, “Perla of Plovdiv “, “Plovdiska Conserves Yellow”, “Arkel “, “Moni”, “Kornel L-1”, “St-176”, “St-72269”, “St-61184” and “Vostok”. Taking into account yield values and duration of flowering, the following promising genotypes for their introduction in the production were selected (“Early Esnap”, “Arkel.” Kornel L-1” and “St–176”). Besides of that it is recommended to work with the less adapted genotypes (“Picardie”, “Picardie Short Cycle”, “Sugar Ann”, “Sweet Green of Provenza”).
