“…These results are similar to those of Belete et al. (2017) who also noted high genetic gains in the yield of eight (08) new varieties compared to one old variety of chickpea in Ethiopia. Unlike morphometric traits, these results on the progress achieved show somewhat the effectiveness of homogenization and mass selection method applied to these agro‐phenological traits (Abreu et al., 2010; Belete et al., 2017; Solieman & Ragheb, 2014).…”

These differences in genetic gains between agro‐phenological and morphometric traits were mainly related to their degrees or coefficients of heritability (Acquaah, 2007).…”

Mass selection of fonio landraces (Digitaria exilis) grown in Benin: Pathway, homogeneity assessment and genotypes screening

Fonio, one of the neglected and underutilized food species in West Africa, is a cereal of great importance to people due to its medicinal and taste qualities (Cruz et al., 2011). It plays a crucial role in the fight against food insecurity for many people, especially during lean season when early varieties enable to control famine (Dramé & Cruz, 2002; Sekloka et al., 2016). In Benin, unlike other cereals such as maize, sorghum, pearl millet and rice grown worldwide, fonio appears to be essentially local crop even endemic to the NorthWest of Benin, in particular Atacora (Dansi et al., 2010; Sekloka et al., 2016). Fonio presents socio-cultural importance, particularly for the Otammari people, in the municipality of Boukombé, the main cropping area, which alone provides 74% of national production (Dramé & Cruz, 2002; Paraïso et al., 2016). Despite its various uses, fonio has remained long neglected in national research programmes. Very little work is available on varietal breeding of this crop (Abdul & Jideani, 2019; Animasaun et al., 2018). In most parts of West Africa where this cereal is grown, there is no formal system for variety selection, production and

“…Ninety three percent of the total variations in grain yield of chickpea varieties were explained by straw yield. Similarly, Belete et al [25] reported that straw yield contributed 97% of the variation in grain yield in chickpea varieties. In general, higher grain yield in chickpea varieties appears to be associated with the production of a higher biomass.…”

Vertisols are suited to dry-land crop production in semi-arid environments since the residual moisture in the soil can support crop growth after the end of the rainy season. However, traditional cropping systems seldom utilize residual moisture of Vertisols for crop production. Farmers need suitable crop species to sustain and enhance their production under such soil and climatic conditions. Chickpea is the strategic crop well adapted to Vertisols and derives most of its water requirements from the residual soil moisture. Yet, different chickpea varieties found to adapt and produce different yields at different locations. The experiments were conducted for two consecutive years (2016 and 2017) on farmers training centers in two districts of Southern Ethiopia. Six released varieties; Arerti, Habru, Yelibe, Naatolii, Fetenech, Kutaye and a Local check were used for the experiment. The trials were laid in a randomized complete block design with four replicates. Data were collected on phenological traits, growth and yield attributes, and grain yield. The results showed that there was significant variation among the tested chickpea varieties in all the agronomic traits recorded. Varieties Arerti and Habru revealed superiority in grain yield, pod setting, hundred seed weight and biomass over the Local check across locations. Based on yielding performance and farmers’ preference, varieties Arerti and Habru are recommended for production in the selected districts and similar agro-ecologies in southern Ethiopia.

“…The gain for sub regions within the same program may show whether the new lines are adapted to specific environmental conditions. In Ethiopia, works pertaining to genetic gain have been documented on bread wheat (Tarekegn et al, 1995), tef (Teklu and Tefera, 2005;Dargo et al, 2016), barley (Fekadu et al, 2011), maize (Worku and Zelleke, 2007), lowland sorghum (Woldesemayat et al, 2015), haricot bean (Bezaweletaw et al, 2006), groundnut (Hagos et al 2012), lentil (Bogale et al, 2015), faba bean (Tolessa et al, 2015) and chick pea (Belete et al, 2017). However, no work has been reported on rice in Ethiopia.…”

Evaluation of varieties from different years in a common environment is one of the most direct methods used to estimate breeding progress. Twenty upland rice varieties released in Ethiopia from 1998 to 2016 were evaluated at Fogera National Rice Research and Training Center in 2017 cropping season to estimate the amount of genetic gain over the years. The varieties were laid out in a randomized complete block design with three replications. Analysis of variance revealed significant differences among varieties for all traits. Grain yield was increased from 2.76 t ha -1 to 4.86 t ha -1 over the past 18 years. The average rate of increase in grain yield of upland rice per year, estimated from the linear regression on year of variety release, was 0.044 t ha -1 with a relative genetic gain of 1.59% year -1 , although non-significant. The study showed significant improvements in grain-filling period, panicles length and number of filled-grains panicle -1 . Significant reduction was also observed in days to heading and thousand-seed weight. No marked changes were observed in grain yield per plant and biological yield, number of fertile tillers, plant height and days to maturity over the 18-year period.
