Many traits play essential roles in determining crop yield. Wide variation for morphological traits exists in Hordeum vulgare L., but the genetic basis of this morphological variation is largely unknown. To understand genetic basis controlling morphological traits affecting yield, a barley doubled haploid population (146 individuals) derived from Clipper × Sahara 3771 was used to map chromosome...

Pre-harvest sprouting (PHS) is one of the serious problems for wheat production, especially in rainy regions. Although seed dormancy is the most critical trait for PHS resistance, the control of heading time should also be considered to prevent seed maturation during unfavorable conditions. In addition, awning is known to enhance water absorption by the spike, causing PHS. In this study, we con...

The awn is a long needle-like structure formed at the tip of the lemma in the florets of some grass species. It plays a role in seed dispersal and protection against animals, and can contribute to the photosynthetic activity of spikes. Three main dominant inhibitors of awn development (Hd, B1 and B2) are known in hexaploid wheat, but the causal genes have not been cloned yet and a genetic assoc...

The growing trend of cropping intensification, mechanisation, the use poor-quality rice seeds, and shift in cultivation methods from transplanting to direct sowing meet food security export demand are causes emergence spread weedy (Oryza sativa f. spontanea) Mekong delta recent years. Therefore, it is necessary study agronomic, morphological, physiological characteristics collected lines help i...

Aim of study: Regarding the third largest staple food crop in world, determining factors affecting wheat yield is great importance. This study aimed to determine useful subsets agronomic traits and evaluate order importance grain yield.
 Area Fars province, Iran.
 Material methods: In total, data corresponding 22 was collected from six different regions (Darab, Kavar, Marvdasht, Fasa,...

Built on the basis of the methods developed for Princeton WordNet (PWN) and EuroWordNet, Arabic WordNet (AWN) has been an interesting project which combines WordNet structure compliance with Arabic particularities. In this paper, some AWN shortcomings related to coverage and usability are addressed. The use of AWN in Question/Answering (Q/A) helped us to deeply evaluate the resource from an exp...
