Genetic gain estimation in a breeding program provides an opportunity to monitor efficiency and genetic progress over specific period. The present study was conducted (i) assess the gains grain yield of early maturing maize hybrids developed by International Maize Wheat Improvement Center (CIMMYT) Southern African during period 2000–2018 (ii) identify key agronomic traits contributing under various management conditions. Seventy-two CIMMYT three commercial checks were assessed stress...
Heterosis is commercially exploited in rapeseed ( Brassica napus L.) and its potential use has been demonstrated turnip rape B. rapa Indian mustard juncea L.). In Ethiopian carinata A. Braun), however, information regarding heterosis not previously reported. This study, therefore, was conducted to generate on combining ability Nine inbred parents their 36 F 1 s, obtained by half‐diallel cross, were evaluated for 12 traits at three locations Ethiopia. Analysis of variance showed the presence...
Abstract Fostering a culture of continuous improvement through regular monitoring genetic trends in breeding pipelines is essential to improve efficiency and increase accountability. This the first global study estimate across International Maize Wheat Improvement Center (CIMMYT) tropical maize eastern southern Africa (ESA), South Asia, Latin America over past decade. Data from total 4152 advanced trials 34,813 entries, conducted at 1331 locations 28 countries globally, were used for this...
Abstract Limited commercial quality protein maize (QPM) varieties with low grain yield potential are currently grown in Eastern and Southern Africa (ESA). This study was conducted to (i) assess the performance of single-cross QPM hybrids that were developed from elite inbred lines using line-by-tester mating design (ii) estimate general (GCA) specific (SCA) combining ability for yield, agronomic traits. One hundred six testcrosses four checks evaluated across environments ESA during 2015...
ABSTRACT Drought and low soil fertility are major abiotic stresses limiting yield of maize ( Zea mays L.) in eastern southern Africa. The present study was undertaken to determine genotype by environment interaction (GEI) grain stability quality protein (QPM) experimental hybrids. A total 108 hybrids, including two commercial checks, were tested across 13 environments under drought, N, optimal Ethiopia, Zambia, Zimbabwe 2015 2016. Environment, hybrid, hybrid × effects significant P <...
Abstract Little is known on maize germplasm adapted to the African highland agro-ecologies. In this study, we analyzed high-density genotyping by sequencing (GBS) data of 298 inbred lines (i) assess extent genetic purity, relatedness, and population structure, (ii) identify genomic regions that have undergone selection (selective sweeps) in response adaptation environments. Nearly 91% pairs differed 30–36% scored alleles, but only 32% had relative kinship coefficient <0.050, which...
Smallholder farmers’ access to and use of quality seeds improved varieties hybrids is an integral component sustainable maize production the reduction yield gap in Ethiopia. Formal seed supply systems play a pivotal role ensuring good increasing productivity maize. However, contribution formal system increase average national country not well documented. This paper specifically analyzes contributions Secondary sources information, including published unpublished data, were used. Analysis...
Simultaneous occurrences of heat and drought stresses have a detrimental effect on growth, development yield maize. Heat is expected to worsen maize losses under climate change. Selecting CDHS tolerant hybrids creates great opportunity for sustainable improvement in the tropics. The objective current investigation was dissect genetic basis tolerance tropical determine performance single cross CDHS. Ninety six single-cross resulted from crossing 12 tassel blast susceptible lines along with...
Characterization of available genetic diversity is a crucial step in effective crop improvement which provide basis for the analysis combining ability and exploitation heterosis inbred lines hybrid breeding. involves evaluation quantitative qualitative attributes given genotypes order to differentiate their usefulness, structure, variability relationships among them. The objectives this study were characterize elite maize adapted highland agro-ecologies classify groups similar by means...
Introduction:In Ethiopia, O. abyssinica has varies economic importance.However, conventional propagation methods of are generally inefficient due to their low multiplication rate, time consuming, labor intensive, and too costly.Aims: The objective this study was develop a protocol for micropropagation through seed culture.Methodology: For disinfection, NaOCl 3, 4, 5% concentration 15, 20, 25 min exposure were tested.MS medium augmented with BAP or KN at different concentrations used shoot...
A field experiment was carried out to study the pattern, rate and duration of seed dry weight (SDW) oil accumulation in two improved noug varieties during 1995 1996. Seeds from uniformly flowered heads were harvested manually seven days after anthesis initiation (DAAI) continued for 60 with four interval. Thousand percent content determined each harvest. The shows that extended reproductive period could be well shortened by selecting plants determinate or semi-determinate growth habit...
‘Yeheb’ (Cordeauxia edulis Hemsl) is a multipurpose and evergreen shrub endemic to southeastern corner of Ethiopia Somalia. It adapted low irregular rainfall survives very long dry season. has enormous economic food security roles the pastoralist Somali Region State in Ethiopia. However, plant threatened with extinction due over exploitation its’ poor natural regeneration capacity. The aim this was explore potential for vitro rapid ‘yeheb’ from cotyledon leaf explants on Murashige Skoog (MS)...
