Improvement in yield of bread wheat cultivars released in Ethiopia from 1949 to 1987
(African Crop Science Society, 1995)
Thirteen bread wheat ( Triticum aestivum check for this species in other resources L.) cultivars popular in the highlands of Ethiopia and representative of the period from 1949 to 1987 were studied for two cropping seasons ...
Genome-wide association for grain yield under rainfed conditions in historical wheat cultivars from Pakistan
Genome-wide association studies (GWAS) were undertaken to identify SNP markers associated with yield and yield-related traits in 123 Pakistani historical wheat cultivars evaluated during 2011–2014 seasons under rainfed ...
Developing and deploying climate-resilient maize varieties in the developing world
In sub-Saharan Africa (SSA) and Asia maize yields remain variable due to climate shocks. Over the past decade extensive progress has been made on the development and delivery of climate-resilient maize. In 2016 over 70 000 ...
Grain yield of wheat as affected by cropping sequence and fertilizer application in Southeastern Ethiopia
(African Crop Science Society, 1997)
Cropping systems in the Ethiopian highlands consist primarily of cereals in rotation with grain legume and oilseed crops; the proportional allocation among crop species varies with altitude, rainfall, and soil type. Barley ...
Genotype by environment interactions and agronomic performance of doubled haploids testcross maize (Zea mays L.) hybrids
In vivo production of maternal haploid plants and advancement in chromosome doubling technology has led to rapid production of doubled haploid homozygous lines. These in turn have boosted rapid advancement in most breeding ...
Response of maize (Zea mays L.) secondary growth parameters to conservation agriculture and conventional tillage systems in Zimbabwe
(Canadian Center of Science and Education, 2016)
Previous, research focused mainly on the effects of conservation agriculture (CA) and conventional practices (CP) on crop yield mostly. A study was conducted at five sites in Zimbabwe from 2012 to 2014 to investigate effects ...
Impact of conservation tillage in rice–based cropping systems on soil aggregation, carbon pools and nutrients
Tillage intensive cropping practices have deteriorated soil physical quality and decreased soil organic carbon (SOC) levels in rice–growing areas of South Asia. Consequently, crop productivity has declined over the years ...
Calidad industrial de trigos harineros mexicanos para temporal. I. Comparación de variedades y causas de la variación
(Sociedad Mexicana de Fitogenética, 2003)
Para determinar el efecto de localidades, genotipos y su interacción, sobre la calidad industrial y el rendimiento de los trigos (Triticum aestivum L.) mexicanos de temporal o de secano, 15 genotipos de trigo harinero ...
Combining ability analysis of RILs developed from a YML32 × Q11 cross for grain yield and resistance to gray leaf spot
(Crop Science Society of America (CSSA), 2018)
The development of resistant lines and hybrids is an economical way to control disease and improve yield stability. The objectives of this study were (i) to investigate if differences in resistance to gray leaf spot (GLS, ...
Avoiding lodging in irrigated spring wheat. I. Stem and root structural requirements
A model of the lodging process has been successfully adapted for use on spring wheat grown in North-West Mexico (NWM). The lodging model was used to estimate the lodging-associated traits required to enable spring wheat ...
