Phenotypic variability of chickpea (Cicer arietinum L) germplasm with temporally varied collection from the Amhara Regional State, Ethiopia

Abstract

Information on the diversity changes occurring in farmers' field overtime is very important for effective genetic resource conservation and use. Thus, this study was initiated to investigate the phenotypic diversity changes between the current (2017) and previous chickpea (Cicer arietinum L.) collections (1979-1983) of the Amhara Regional State, Ethiopia. An experiment was conducted using simple lattice design with two replications at Debra Zeit Agricultural Research Center for two consecutive years (2018/2019 to 2019/2020). Genetic erosion of 30.4% to 100% was recorded in chickpea for the past 35 years in the study areas. Shannon-Weaver diversity index estimates of black seeded and ivory white seeded chickpea types decreased from 1.99 to 0.69 and 1.33 to 0.0 in the past 35 years, respectively. In previous collections, 25.8% of black and 6.5% of white-coated genotypes were observed, while these chickpea types were rare (black 6.5%) or unobtainable (white 0.0%) in current collections. There was a significant difference (p < 0.05) between Sintayehu Admas ABOUT THE AUTHOR Sintayehu Admas (PhD Candidate) and Eleni Shiferaw (PhD) are researchers working at the Ethiopian Biodiversity Institute. Their research work focuses on crop genetic resources exploration, collection, characterization and evaluation for desirable traits by employing morphological, biochemical and molecular tools.

SSR Genotyping and Marker–Trait Association with Yield Components in a Kazakh Germplasm Collection of Chickpea (Cicer arietinum L.)

“…Similar results were obtained in many studies including chickpea [61,62]. The current results confirm that clustering using molecular markers does not always divide samples by their origins, and it depends on various factors such as pedigree and breeding, as well as the exchange of genetic materials with gene flow and mutations [63,64].…”

Variations in Phenotypic Characteristics of Vigna Unguiculata (L) Walp. Seeds Sourced From Open Markets in Benin City, Nigeria

“…Cowpea is a staple food in Nigeria and in Africa due to its hardiness, versatility, and popularity. The seed shapes, sizes, colours, texture, pigmentation, and growth patterns of cowpea varieties in Nigeria differ greatly [1][2][3][4][5][6][7][8][9][10]. Unfortunately, the ever-changing environment, volatile global economy, and intensification of low-input agricultural production have resulted in a dramatic increase in soil depletion and nutrient depletion in many Sub-Saharan African regions [11].…”

Genetic variability and population structure of Ethiopian chickpea (Cicer arietinum L.) germplasm

“…Comprehensive information on genetic diversity and structure can be generated from morphological, biochemical and molecular data. Ethiopian chickpea germplasm have been characterized extensively for phenotypic characteristics [15][16][17][18][19][20]. Although morphological markers allow the identification of genetic variation, it is masked by environmental factors and is minimized due to the lack of distinguishable morphological markers [21].…”
