CHARACTERIZATION OF TURKISH EDIBLE PEA GENE RESOURCES AND THEIR UTILISATION IN BREEDING PROGRAMS
Durdane MART
Abstract
Total 70 different genotypes sourced from local edible pea (Pisum sativum L.) populations were obtained from the Izmir gene bank and cropped in the Eastern Mediterranean Agricultural Research Institute to morphologically characterize the genotypes. Morphological characterization studies were carried out according to the identification list published by IPGRI for peas and the UPOV feature document for peas. The characteristics of the pea plants and their seeds were examined and the differences between these characteristics were determined. It was aimed to determine the vegetative characteristics of the related pea populations, to assist selections of pre-breeding material and start breeding studies for cultivar development.Plant height, first pod height, number of main branches and number of pods per plant of the examined pea populations were 32-135 cm; 17-85 cm; 1-4; 1-26, respectively. The number of full pods per plant, pod length, number of grains per plant, grain weight per plant and plot yields values were varied between 1-30; 3-9 cm; 2-118; 1-83 g and 50-434 kg/9m2, respectively. It was determined that the number of pods, number of full pods, number of grains, plant straw weight and plant grain weight were effective on the first main component. Seed color, pod length, seed color, hilum color and plot yield were found to be effective on the second main component. In the third main component, the effect of plant height and first pod height characteristics was determined. It was concluded that there are promising genotypes in terms of breeding, and selection work should be continued in these genotypes.
