Genetic diversity is fundamentally important in crop improvement and provides plants with the capacity to meet demands of changing environments. This work was carried out assess extent genetic relatedness among a number assembled cassava (Manihot esculenta Crantz) accessions. We conducted microsatellite marker analysis 89 accessions collected from Ghanaian exotic sources. These were assayed using 35 simple sequence repeat (SSR) markers. A total 167 alleles detected polymorphic markers an...
Crowdsourced citizen science is an emerging approach in plant sciences. The triadic comparison of technologies (tricot) has been successfully utilized by demand-led breeding programmes to identify varieties for dissemination suited specific geographic and climatic regions. An important feature this the independent way which farmers individually evaluate on their own farms as “citizen scientists.” In study, we adapted consumer preferences boiled sweetpotato [ Ipomoea batatas (L.) Lam] roots...
Abstract Sweetpotato ( Ipomoea batatas L.) was known as a minor root crop in Ghana. Starting 2010, the International Potato Center (CIP) and multiple partners implemented orange‐fleshed sweetpotato (OFSP) projects to reposition this CIP‐led from 2010 2021 were identified Research for Development Initiative projects. These consisted of (i) new variety development commercial seed systems (Sweetpotato Action Security Health Africa: 2009–2019); (ii) OFSP products business development,...
Early bulking in cassava (Manihot esculenta Crantz) is a very important trait semi-arid ecologies of the tropics. Farmers tend to select early-maturing varieties escape terminal drought and destruction by domestic animals during dry season. However, early harvesting associated with yield penalty due unavailability high-yielding varieties. In order develop early-bulking for savanna ecologies, this study was carried out assess genetic variation pattern storage root as well traits under...
A field experiment was conducted at Savanna Agricultural Research Institute in 2015 cropping season to examine the inheritance of early maturity among an extra-early maturing landrace Sanzi and a medium variety Padi-Tuya their progenies. The results indicated highly significant (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mi>P</mml:mi><mml:mo><</mml:mo><mml:mn fontstyle="italic">0.01</mml:mn></mml:math>) genetic variations for indices, namely, days first flower...
Information on combining ability and reciprocal effects (REC) facilitates efficient utilization of genetic materials in a breeding program. This study was conducted (at the CSIR-Savanna Agricultural Research Institute, Ghana) to determine general (GCA) specific (SCA), heritability, advance, GCA, SCA as well relationship between parents per se performance progenies for yield components maturity traits cowpea. The test populations were derived using 5 × complete diallel cross with different...
Knowledge of the genetic mechanisms conditioning drought tolerance in maize is crucial to success hybrid breeding programs aimed at developing high-yielding cultivars under drought. The objectives this study were determine combining ability extra-early inbreds, compute heritability measured traits, assess performance inbreds combinations and investigate associations among traits optimal conditions. A total 252 hybrids generated by crossing 63 four testers, along with commercial checks,...
Social Impact Statement The use of neglected and underutilized species (NUS) in agrosystems is a potential solution to the challenges arising from global change. These could contribute equitable diversification agricultural systems. Providing knowledge on their genetic diversity fostering access data results essential for development strong collaborative future research. study addressed these issues by assessing largest fonio ( Digitaria exilis ) collection existing date. Associated with...
Abstract Sweetpotato ( Ipomoea batatas (L) Lam) is prioritized among crops that enhance food security and reduce malnutrition in Ghana. The production expanding faster than other owing to its superior nutrient composition. This study evaluates integrated approaches increase on‐farm productivity, income, utilization of sweetpotato. first part evaluated the agronomic yield performance, financial return, sensory quality 10 varieties under different fertilizer treatments. second activities...
This study evaluates the effectiveness of stone bunds in enhancing soil moisture, vegetation health, and crop yields Ghana’s semi-arid Upper East Region, an important area for agricultural productivity West Africa. In this region, practices are heavily impacted by erratic rainfall poor moisture retention, threatening food security. Despite known benefits traditional conservation like bunds, their context has not been fully quantified. Field remote sensing data were used to evaluate influence...
Early Leaf Spot (ELS) caused by the fungus Passalora arachidicola and Late (LLS) also Nothopassalora personata, are two major groundnut ( Arachis hypogaea L.) destructive diseases in Ghana. Accurate phenotyping genotyping to develop genotypes resistant Diseases (LSD) increase production is critically important Western Africa. Two experiments were conducted at Council for Scientific Industrial Research-Savanna Agricultural Research Institute located Nyankpala, Ghana explore effectiveness of...
Cassava farmers from three production districts in Northern and Savannah Regions were sampled for their perceptions on drought, constraints preferences new cassava varieties. The levels of agreement farmers' responses tested using Kendall's Coefficient Concordance (KOC). results indicated lack credit as the major constraint followed by improved varieties, diseases pests' infestation. Drought was identified a challenge with increasing intensity. Most adopt early planting maturing varieties...
Development of maize hybrids that possess tolerant genes to low soil nitrogen is critical for long-term production in areas with fertility. In this study, estimates combining ability effects grain yield and secondary traits selected inbred lines, identify potential parents hybrid development the crosses under sub-optimal optimal N environments. One hundred were evaluated environments two years. The experimental layout was a 10 × alpha lattice design replications experiments. results obtained...
Tomato, an important vegetable crop cultivated worldwide is essential component of the Ghanaian diet. However, production in Ghana hampered by heat stress (HS) during certain periods year. Tomato sensitive to HS, especially reproductive stage, inducing pollen sterility, floral and fruit abortion, culminating low yield. This necessitates development HS-tolerant tomato varieties. The HS-tolerance potential 13 lines was assessed under both poly-house open field conditions at day temperatures...
Studies were conducted to determine tuber yield stability and adaptability of some elite yam (Dioscorea sp.) genotypes in northern Ghana. Ten exotic alongside one locally cultivated farmer-preferred variety, Laribako, grown five environments between 2010 2012. These 11 arranged a randomised complete block design with three replications assessed for components. Analysis variance indicated significant <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"> <mfenced open="(" close=")"...
In this study, the differential rankings of 36 groundnut genotypes under varying environmental conditions were studied at various levels phenotype. Locations that are generally accepted by crop- and soil-based research community to represent entire Guinea Sudan Savanna agro-ecological zones in Ghana characterized, time using a crop. The characterization was done based on four farmer-preferred traits (early late leaf spot disease ratings, haulm pod yields) three models (i.e., AMMI, GGE,...
