Abstract: The threshing loss in chickpea (Cicer arietinum L.) is influenced by environmental conditions, the genotypes and their status during the harvesting, the trashing technology and machines, as well as the parameters of their operating mode. The aim of the study is the evaluation of number of chickpea genotypes, part of the National Gene Bank collection, in terms of their resistance to pedicel detachment, combined with other valuable traits. In the course of two years (2020-2021), chickpea accessions were assessed in field experiments by economically important traits according to the International Chickpea Descriptor (UPOV, 2019). By laboratory tests, through an experimental setup, the energy to detach the pedicel of the pod from the chickpea stalk was determined. The phenotypic and genotypic coefficients were also determined.
The highest average energy value to detach the pod pedicel was established in B9E0014 accession, followed by BGR23151, A8E0412 and B9E0149. The B9E0014 accession was characterized by tall plants, high setting of the first pod and big mass of 100 grains, while BGR23151 distinguished by big numbers of branches, pods and grains per plant. Phenotypic and genotypic coefficients of variation were distinguished by high values. It was found that resistance to the pod pedicel detachment was mostly influenced by the interaction between the genotype and the moisture of the grains, followed by genotype with p=0.04<α=0.05. The genotype BGR23151 is recommended for direct implementation in practice.
