Abstract

The experiment was done on 202 new chickpea (Cicer arietinum L.) landraces with 2 checks to assess the association, direct and indirect effect of different characters on yield. The experiment was planted at Sirinka and Jari, Ethiopia, under rain fed condition in 2016 using alpha lattice design with three replications. Data were collected on yield and yield related traits. Analysis of variance showed highly significant differences among genotypes. The correlation of grain yield with biomass and with harvest index was positive and highly significant both at genotypic and phenotypic levels. In addition, its association with pod filling period, plant height, secondary branches and hundred seed mass was positive but insignificant both at genotypic and phenotypic levels. Path coefficient analysis at genotypic level showed that among the 15 causal (independent) traits; biomass, harvest index, pod length, days to pod setting, pod filing period, canopy width, primary branches, secondary branches, and number of pods per plant had positive and directly influence on grain yield. Although the days to flowering, plant height and hundred seed mass had positive genotypic correlation with grain yield. In general correlation coupled with path coefficient analysis revealed that biomass and harvest index had a direct relationship with seed yield.

Highlights

Chickpea (Cicer arietinum L.) is the third most important pulse crop in the world, after dry common bean and field pea (Padmavathiv et al, 2013)
Southeast Turkey and Syria are considered as the two primary centers of origin of chickpea (Singh et al, 1997)
India is the largest chickpea producing country accounting for 72 % of the global chickpea production (Ojiewo, 2016)

Summary

Introduction

Chickpea (Cicer arietinum L.) is the third most important pulse crop in the world, after dry common bean and field pea (Padmavathiv et al, 2013). Southeast Turkey and Syria are considered as the two primary centers of origin of chickpea (Singh et al, 1997). The world chickpea production reached 13.3 million tons in 2013 and 14.2 million tons in 2014 (FAO, 2014). India is the largest chickpea producing country accounting for 72 % of the global chickpea production (Ojiewo, 2016). Ethiopia is considered as one of the secondary centers of diversity for chickpea (van der Maesen, 1987). In Ethiopia, chickpea is the third largest legume crop in area and production (CSA, 2015)
