In order to study the correlation of agronomic, morphologic and physiologic traits and their effects on grain yield of rice genotypes in two environments (favorable irrigation and water stress), 49 genotypes were evaluated using a completely randomized block design with 3 replications in two experimental conditions. All practices and conditions were the same for the two experiments with the exc...

Tobacco (Nicotiana tabacum L.) is one of valuable agricultural and industrial crops. Studying most important traits of tobacco is difficult because of quantitative nature that are controlled by multiple genes and affected by environmental factors. Among various methods for the study of quantitative traits, association mapping which utilize phenotypic and DNA markers information is one of the ef...

Selection of high yielding genotypes is very important in sunflower. Thus, 24 new sunflower hybrids along with Golsa cultivar were evaluated in a simple lattice design (5×5) with two replications in the Agriculture Research Station of Gorgan, north of Iran, during 2020. The genotype by yield × trait (GYT) biplot method was used in order to study the relationships between different traits and to...

Study of heritability and gene action to improve agronomic and physiological traits, especially under drought stress conditions, are very important. The objectives of this study were to investigate heritability for important agronomic traits and some physiological characters in a cross between two spring wheat cultivars. The experiment was carried out using different generations (BC1, BC2, F3, ...

In order to investigation effect of hexaconazole in some morpho- physiological traits of Althaea officinalis in drought stress, the experiment was conducted factorial in the base of complete randomized design with four replications in greenhouse of Islamic Azad university of Neyshabur branch in 2012- 2013. Treatments were drought (50%) and control (100%) field capacity and sparying of hexaconaz...

In order to investigate genetic diversity and heritability of some morphological traits in five bread wheat (Triticum aestivum L.) cultivars, two separate experiments were conducted based on randomized compeletly blocks design (RCBD) with 3 replications under stress and normal conditions. The results showed that differences between cultivars were significant for the majority of traits in both c...

This research was carried out to evaluate the effect of spraying different concentrations of Gibberellin (GA3), Benzyladenin (BA) and Ethanol on growth and flowering of Zontledechia ethiopica. Experiments were carried out in a randomized complete block design with three replications in greenhouse and with 12 spraying treatments include: GA3 (500, 250, 100 and 1000 mg L-1), BA (100, 200 and 500 ...
