Multi-environment trials (METs) of crop genotypes are costly and require efficient test sites for cost effectiveness. This study aimed to identify efficient test sites for METs of sugarcane (Saccharum spp.) genotypes in Thailand, utilizing data from 10 sugarcane genotypes conducted at nine locations covering different sugarcane growing regions of the country for two crop-classes. Cluster an...

Crop rotation is one of the most relevant tools for Integrated Weed Management (IWM). In semiarid Mediterranean areas, crop limited by climatic conditions. Camelina (Camelina sativa (L.) Crantz) an interesting option to introduce due its tolerance cold and drought because short life cycle, which allows a flexible management weed control. this study, capacity camelina reduce growth seed rain cor...

Describing genetic diversity in wild barley (Hordeum vulgare ssp. spontaneum) in geographic and environmental space in the context of current, past and potential future climates is important for conservation and for breeding the domesticated crop (Hordeum vulgare ssp. vulgare). Spatial genetic diversity in wild barley was revealed by both nuclear- (2,505 SNP, 24 nSSR) and chloroplast-derived (5...

abstract this study was conducted under cold climate condition in khorasan during 2006-2008 growing seasons to evaluation of soil fertility in wheat-based double cropping systems under different rate of nitrogen and return of crop residues. a randomized complete block design with split-split plot arrangement and three replicates was used. main plots were five crop rotations namely: wheat-wheat,...

Plant diseases are a serious threat to crop production. The informed use of naturally occurring disease resistance in plant breeding can greatly contribute to sustainably reduce yield losses caused by plant pathogens. The Ta-Lr34res gene encodes an ABC transporter protein and confers partial, durable, and broad spectrum resistance against several fungal pathogens in wheat. Transgenic barley lin...

Barley yellow dwarf (BYD), the most common and widespread virus disease of cereal crops worldwide (14), may be caused by any one of several Barley yellow dwarf viruses (BYDVs) of the family Luteoviridae. Transmitted by at least 25 aphid species (24), these viruses historically have been classified into two subgroups and five strains based on aphid vector specificity and efficiency (31). However...

in order to evaluate the weed diversity in forage crop fields such as alfalfa (medicago sativa l.), clover (trifolium sp.) and sainfoin (onobrychis spp.) in different provinces of iran, a study was conducted by using data from reports of plant protection organization, ministry of agriculture during 2008. after evaluation of weed species and definition of weed family, these species classified ba...
