Safflower (Carthamus tinctorius L.) is an only oilseed crop which, is native to Iran where, is known as its diversity center. The genetic variation study provides valuable information about maintenance and their usage of germplasm for breeders to increase efficiency of breeding programs. In the current study, sixty-four genotypes were assessed for 20 agronomic nag morphological traits for genet...

Among cereal crops, wheat has been identified as a major source for human food consumption. Wheat breeders require access to new genetic diversity resources satisfy the demands of growing population more with high quality that can be produced in variable environmental conditions. The close relatives domesticated wheats represent an ideal gene pool use breeders. genera Aegilops and Triticum are ...

Study of potential of alfalfa ecotypes in biomass partitioning and harvestable and non-harvestable parts as well as induction of summer dormancy under water scarcity can lead to develop adapted cultivars for sustainable farming system andto meet targets of the breeding program. Therefore, this experiment was conducted with 10 alfalfa ecotypes under four irrigation managements at Seed and Plant ...

pyramiding genes related to grain quality and resistance through marker assisted selection (mas) is an important approach in rice breeding programs. marker-assisted selection can be used for monitoring the presence or absence of these genes in breeding populations and can be combined with conventional breeding approaches. this study is a part of cultivar development program in iran through inte...

Molecular marker assisted selection (MAS) has been touted as a means to improve the efficiency and speed of plant selection programs. The most widespread use of MAS to date is to assist backcrossing of major genes into already proven, elite cultivars. Markers can aid selection for target alleles that are not easily assayed in individual plants, minimize linkage drag around the target gene, and ...

boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...

The crop legumes such as chickpea, common bean, cowpea, peanut, pigeonpea, soybean, etc. are important sources of nutrition and contribute to a significant amount of biological nitrogen fixation (>20 million tons of fixed nitrogen) in agriculture. However, the production of legumes is constrained due to abiotic and biotic stresses. It is therefore imperative to understand the molecular mechanis...
