Low temperature tolerance is the main predictor of variation in the global distribution and performance of insects, yet the molecular mechanisms underlying cold tolerance variation are poorly known, and it is unclear whether the mechanisms that improve cold tolerance within the lifetime of an individual insect are similar to those that underlie evolved differences among species. The accumulatio...

Four maize (Zea mays L.) inbreds representing genetic differences in seedling cold tolerance were used to determine the effect of growth temperatures on dry weight accumulation and mitochondrial properties, especially the alternative oxidase capacity. Seedlings were grown in darkness at 30 degrees C (constant), 14 degrees C (constant), and 15 degrees C for 16 hours and 8 degrees C for 8 hours. ...

selecting and introducing of cold tolerant chickpea varieties with high yielding potential as well as suitable to autumn sowing has highly importance. sel93th24460 is hybrid of a cross, ilc 3470 × ilc 8617 which has done at international center for agricultural research in the dry areas (icarda). this genotype has been sent to iran in an international cold tolerance nursery in 1999 and evaluate...

Apricot is grown in a wide range of climatic conditions in Iran, however, it is frequently damaged by late spring frost. In this case, identification of new genotypes tolerant to cold stress is indispensably needed. The objective of this study was to evaluate the genetic population and relationships among 27 apricot accessions (Prunus armeniaca) by 30 microsatellite markers and 11 morp...

Among seven varieties screened, Amber was found resistant to Thrips and Bean Cowpea Yellow Mosaic Virus tolerant cold with yield of 13.66 q/ha, followed by Utkarsh susceptible all sucking insect pest, but BCMV Cold 11.58 q/ha. Uday (Bold seeded) variety at par 11.22 cold. Moderate yields were recorded in Arun (6.96 q/ha) which is also pests, Arka Komal (6.14 Chintapalle Red (5.62 q/ha). Phalgun...
