Gibberella ear rot (GER) is one of the most economically important fungal diseases maize in temperate zone due to moldy grain contaminated with health threatening mycotoxins. To develop resistant genotypes and control disease, understanding host-pathogen interaction essential. RNA-Seq-derived transcriptome profiles fungal- mock-inoculated developing kernel tissues two inbred lines were used identify differentially expressed transcripts propose candidate genes mapping within GER resistance...
Abstract Molecular mapping of crown rust resistance genes is important to effectively utilize these and improve breeding efficiency through marker-assisted selection. Pc45 a major race-specific gene initially identified in the wild hexaploid oat Avena sterilis early 1970s. This was transferred cultivated (Avena sativa) has been used as differential for identification races since 1974. Previous research an association between virulence PcKM, varieties ‘Kame’ ‘Morton’. study undertaken reveal...
ABSTRACT To optimize the efficiency of maize ( Zea mays L.) drought breeding, ability to predict testcross performance (TP) under stress using line per se (LP) parental inbreds would be useful. We evaluated LP and TP tropical in well‐watered environments Kenya Mexico. Our main objective was determine if predictive for grain yield selection result reduced potential conditions. Average reduction 77% lines 68% testcrosses. genotypic correlations between testcrosses were positive low (genotypic...
Crown rust, caused by Puccinia coronata f. sp. avenae Eriks. (Pca), is among the most important oat diseases resulting in significant yield losses many growing regions. A gene-for-gene interaction well established this pathosystem and has been exploited breeders to control crown rust. Pc39 a seedling rust resistance gene that widely deployed North American breeding. DNA markers are desired accurately predict specific Pc genes present breeding germplasm. The objectives of study were as...
Abstract The exchange of elite breeding materials across regions is an important way in which multinational maize programmes access new genetic variation, improve efficiency and reduce costs. Our objectives were to examine whether CIMMYT 's for tropical subtropical environments Mexico Eastern Southern Africa ( ESA ) can effectively share materials. Sets selected unselected lines evaluated per se testcross performance multiple grain yield, days anthesis plant height. Genotypic correlations...
The prevalence of maize, wheat and other cereal crops in Ontario, Canada, has led to frequent epidemics ear rot head blight disease caused by the broad host pathogen Fusarium graminearum. This fungus produces trichothecene deoxynivalenol (DON) which is one most common mycotoxins contaminating food feed globally poses a risk human animal health. DON commonly glycosylated plant hosts into deoxynivalenol-3-glucoside (DON-3G) as part defence mechanism detoxify sequester mycotoxins. However, it...
Resistance breeding is the most effective method to control northern corn leaf blight (NCLB). The objectives were (1) Assess effects of dominant genes (Ht(s)), polygene (PG), and their combinations disease rating (DR), number lesions per (NLPL), lesion size (LS); (2) Estimate genetic components, general combining abilities (GCA), heritability under two Line × Tester analyses; (3) Determine gene action through mid-parent heterosis (MPH) better-parent heterobeltiosis (BPH) analysis. A total...
Resistance breeding is the most economic method to control northern corn leaf blight (NCLB). The objectives of these studies were: To assess effects dominant genes (Ht(s)), polygene (PG), and combinations on percent area affected (PLAA), yield, kernel moisture, number per ear, 100-kernel weight; understand genetic action combinations; predict losses resistant for yield traits with PLAA; under different NCLB epidemic conditions. Two experiments were conducted. E1 had 120 crosses, their...
CO476 is an early-medium maturity (76 d to flowering), mostly stiff stalk (BSSS), yellow flint inbred which combines well with a B14-type and Iodent-type testers in many different locations. possesses moderate resistance gibberella ear rot both the hybrid combinations. It has intermediate response common smut, Fusarium rot, northern corn leaf blight, rust, Goss’s wilt.
CO475 is an early-medium maturity (75 d to flowering), mostly Iodent, yellow semi-dent inbred that combines well with several testers in many different locations. It has moderate resistance gibberella ear rot (both the and hybrid combinations) intermediate response smut, Fusarium stalk rot, northern leaf blight, eyespot, rust, goss’s wilt.
Stem rust is an important disease of cultivated oat (Avena sativa) caused by Puccinia graminis f. sp. avenae. In North America, host resistance the primary strategy to control this and conferred a relatively small number genes. Pg2 widely deployed stem gene that originates from oat. Oat breeders wish develop cultivars with multiple Pg genes slow breakdown single resistance, often require DNA markers suited for marker-assisted selection. Our objectives were (i) construct high density linkage...
CO481 is an early maturing (57–58 days to flowering, 1283–1310 crop heat units (CHUs)) yellow, semi-dent inbred line. has mixed heterotic group and combines well with stiff stalk testers produce hybrids high grain yield. Additional key features include fast kernel drydown rate moderate resistance gibberella ear rot. most suitable for short-season regions of North America CHUs ranging from 2500 2750. These the corn-growing Canada in Prince Edward Island, eastern parts Ontario, southern...
CO474 is a mostly Stiff Stalk (BSSS), yellow, semi-dent inbred with early-medium maturity (75 d to flowering). It has moderate resistance eyespot and rust intermediate reactions Fusarium stalk rot, northern leaf blight, goss’s wilt. This combines well several testers in many different locations.
CO477, CO478, CO479, and CO480 are mid- to late-season [75–81 d flowering, crop heat units (CHU) = 1720–1855] corn (Zea mays L.) inbred lines with high stalk sugar levels. The level of in the stalks very especially when grown as lines. On average, yield three times more than their testcrosses. These first be developed released for biofuel production, from breeding program Agriculture Agri-Food Canada. Additionally, these can used (or) silage production. They have moderate intermediate...
