ABSTRACT

ABSTRACT: Cultivated Pisum is dominated with Pisum sativum subgroup, but Pisum sativum var. abyssinicum (Dekoko) is a unique subgroup developed and cultivated in Ethiopia. The objectives of the study were characterization of Dekoko accessions using 17 quantitative traits and study the genetic variability present in the population. Twenty-four accessions of Dekoko (Pisum sativum var. abyssinicum) collected from North Ethiopia (South Tigray and North Wello) by Alamata Agricultural Research Center, were planted in 3 replications of the RCBD design at Mekhan farmers' Training Centre in Endamekhoni in 2010. Considerable extent of genetic variability was available for days to flowering, leaf area index and crude protein content while the remaining quantitative traits did not show statistically significant variation in the population of Dekoko studied. Protein content ranged between 17.9% (T-018/08 Ko) to 38.4% (T-010/08 K. Traits such as days to flowering and maturity and leaf width had low Phenotypic Coefficient of Variation, Genotypic Coefficient of Variation and low genetic advance (<20%). Clustering of the accessions using quantitative traits indicated that the number of accessions in each cluster varied from 1 in cluster IV to 11 in cluster I.
