Abstract The parasitic purple witchweed [ Striga hermonthica (Del.) Benth.] is a serious constraint to maize production in sub-Saharan Africa, especially poor soils. Various spp. control measures have been developed, but these not assessed an integrated system. This study was conducted evaluate set of promising technologies for S. management western Kenya. We evaluated three genotypes either intercropped with peanut ( Arachis hypogaea L.), soybean Glycine max (L.) Merr.], or silverleaf...
Enriching of kernel zinc (Zn) concentration in maize is one the most effective ways to solve problem Zn deficiency low and middle income countries where major staple food, 17% global population affected with deficiency. Genomic selection (GS) has shown be an approach accelerate genetic gains plant breeding. In present study, association-mapping panel two double-haploid (DH) populations, both genotyped genotyping-by-sequencing (GBS) repeat amplification sequencing (rAmpSeq) markers, were used...
Zinc (Zn) deficiency is a major risk factor for human health, affecting about 30% of the world's population. To study potential genomic selection (GS) maize with increased Zn concentration, an association panel and two doubled haploid (DH) populations were evaluated in three environments. Three prediction models, M (M1: Environment + Line, M2: Line Genomic, M3: Genomic x Environment) incorporating main effects (lines genomic) interaction between environment (G E) assessed to estimate ability...
Genetic improvement of maize with elevated levels zinc (Zn) can reduce Zn deficiency among populations who rely on as a staple. Inbred lines quality protein (QPM) and non-QPM in the kernel have been identified. However, information about optimal strategy to utilize germplasm breeding for high-Zn concentration is lacking. As preliminary step, this study was conducted ascertain potential QPM, non-QPM, or combination QPM hybrids attaining desirable concentration. Twenty elite inbreds, 10 were...
Common rust (CR) caused by
Early-maturing maize (Zea Mays L.) germplasm developed from diverse sources has the potential for use in developing hybrids suitable increasing production dry ecologies of eastern Africa. A diallel study was conducted to estimate general combining ability (GCA) 12 early-maturing inbred lines, identify single-cross as parents, assess genetic diversity among and relate distance specific (SCA) hybrid performance. Sixty-six F1 were evaluated under optimal drought stress conditions at four...
