Identification of Initial Material for Organic Breeding in Garden Pea

Abstract

It evaluated the productivity, disease, pest infestation, and seed quality in four garden pea accessions, grown at four organic production systems. The attempt was performed in the experimental plot of the Maritsa Vegetable Crops Research Institute – Plovdiv, Bulgaria during the period 2009 – 2010. High productivity in mid-early line № К102 at four variants of organic growing was recorded. The mid-late line № 6/00 is suitable for growing in the conditions of natural fertility with biological plant protection. The productivity of a variety of Marsi is the highest in fertilization with biohumus and in the application of bioinsecticides for plant protection. The productivity of the early variety Musala does not exceed the standard. The infestation of diseases and pests is strongly expressed in early group varieties (for Fusarium spp. up to 11.94 % and strong up to 63.50% for Bruchus Pisi L. The percentage of the infestation is low in Laspeyresia spp. to 6.42% and to 3.44% in Pythium spp. A lower degree of infestation was recorded in organic production systems with the application of bioinsecticides. Garden pea seeds that were obtained have lower absolute weight than those recorded in conventional production but the germination is kept the same from 90.25% to 98%.
