<title>Abstract</title> Use of molecular markers has improved the analysis genetic variation by eliminating environmental influences on genotype performance. The objective this study was to assess diversity and population structure 327 sweetpotato genotypes sourced from major sweetpotato-growing regions Zimbabwe International Potato Centre (CIP) in Mozambique using low-density Diversity Array Technology (DArTseq) SNP chip covering 90 chromosomes sweetpotato. genotypes' (GD) varied 0.12 0.50,...
Assessing genetic gains from historical data provides insights to improve breeding programs. This study evaluated the Mozambique National Maize Program’s (MNMP’s) using advanced germplasm trials conducted at 21 locations between 2014 and 2020. Genetic were calculated by regressing genotypic best linear unbiased estimates of grain yield complementary agronomic traits against initial year genotype evaluation (n = 592). The annual gain was expressed as a percentage trait mean. While yield,...
Estimating genetic gains is vital to optimize breeding programs for increased efficiency. Genetic should translate into productivity if returns investments in and impact are be realized. The objective of this study was estimate gain grain yield key agronomic traits pre-commercial commercial maize varieties from public private tested (i) national performance trials (NPT), (ii) era trial and, (iii) compare the trends with average. used historical NPT data on 419 improved evaluated 23 at 6-8...
Monitoring genetic gains within breeding programs is a critical component for continuous improvement. While several national in Africa have assessed gain using era studies, this study the first to use two decades of historical data estimate trends program. The objective was assess final stages Zimbabwe’s Department Research &amp; Specialist Services maize pipeline between 2002 and 2021. Data from 107 intermediate 162 advanced variety trials, comprising 716 398 entries, respectively,...
Optimization of a breeding program requires assessing and quantifying empirical genetic trends made through past efforts relative to the current strategies, germplasm, technologies, policy. To establish in Kenyan Highland Maize Breeding Program (KHMP), two-decade (1999-2020) historical dataset from Preliminary Variety Trials (PVT) Advanced (AVT) was analyzed. A mixed model analysis used compute gains for traits based on best linear unbiased estimates PVT AVT evaluation stages. positive...
Knowledge of the effects introgressing temperate maize germplasm in tropical elite inbred lines on genetic variation and relationship between grain yield its components is limited. In this study, objective was to evaluate introgressed for selected economic traits. Field evaluation carried out 122 comprising sets from three selection environments, parental two common checks. Genetic significant (P &lt; 0.05) all major traits among within across sets. Heritability estimates ranged low...
The study evaluated new biofortified, high-yielding and disease-resistant bean varieties for their adaptability in Zimbabwe. secondary objective was to assess the association between yield other traits that contribute grain identify have direct indirect effects on yield. conducted December 2016 June 2017 using an augmented design with 24 replicated three times at Chinhoyi University of Technology Research Farm. Data analysed analysis variance statistical system (SAS) software. DAB482, DAB494...
The study was carried out to determine the effect of male planting date (MPD) and female plant population (FPP) on grain yield (GY) performance a three-way hybrid evaluate Hybrid-Maize simulation model for estimation in seed maize production. Fifteen treatment combinations five MPD as deviation from three FPP replicated times were used. programme used forecast possible GY outcomes fifteen treatments experiment using estimated parameters weather data 2006/7 season. field produced significant...
Grain yield potential of new maize hybrid varieties across target environments contributes to the uptake these by farmers. Evaluation single-cross hybrids developed from test crossing introgressed inbred lines bred for three distinct elite tropical line testers was carried out. The study&rsquo;s objective assess grain stability and genotype adaptability South African relative adapted commercial checks. One hundred twenty-two using pedigree breeding program were crossed four &times;...
