An experiment was conducted to investigate the genetic diversity in the cultivars and F1 hybrids of durum wheat, using agronomic and morphological traits. Evaluation of consistency between choosing parents of crosses based on morphological and agronomic observations and genetic distance obtained from cluster analysis were objectives of this study. Fourty- two genotypes were evaluated using a ra...

Diallel analysis was used to estimate the combining ability, gene action, gene number, heritabilties and other genetic parameters of a set of wheat genotypes. For this purpose, nine parents and their 36 crosses were evaluated for 9 traits in a randomized complete block design with three replications in 1996. The analysis of variance revealed significant differences among all genotypes for all ...

In this research, 50 quinoa genotypes were investigated using 40 pairs of microsatellite markers (SSR) to identify the superior genotypes in terms of grain yield, the components affecting it, and the features linked to the studied traits were also introduced using Association Analysis. The study of grain yield traits and the factors affecting it showed that the traits of day to physiological ma...

Genetic variation of 300 genotypes of durum wheat comprising CIMMYT/ICARDA and Iranian germplasm was evaluated in 1999-2000 at Researh Farm of College of Agriculture, Isfahan University of Technology located at Lavark, NaJaf-Abad. Days to heading, days to maturity, plant height, spike length, grain weight per spike, number of grain per spike, number of spikes per m2, 1000-grain weight, test wei...

Extended Abstract Introduction and Objective: Due to the very high diversity among the genotypes of quinoa (Chenopodium quinoa), it has shown a very high adaptability and stability in different climates. Therefore, this experiment was performed to investigate the morphological and genetic diversity of 14 quinoa genotypes and compare them with the control genotype of the region (Titicaca). Ma...

To determine gene action and heritability of grain yield related traits in rice, six rice varieties including Hashemi, Vandana, Kadous, Hassani, Shahpasand and IR36 were crossed in a diallel design in 2010. The parents and seeds of F1 generation (36 genotypes) were grown in a completely randomized block design with three replications at the Research Field of the Rice Research Institute of Iran-...

Considering to drought stress importance as most important limiting factor in rice production in world, identification of tolerant genotypes to drought can be a valuable approach to deal with the drought stress. In the present experiment plant materials contains 53 rice genotypes including 31 aerobic and 22 lowland (landrace) rice that were grown in two conditions under drought stress and norma...
