In order to evaluate and grouping wheat genotypes based on grain yield and important agronomic traits under drought stress, a field experiment was conducted with 43 wheat genotypes using a Randomized Complete Block design in three replication at Azad University, khorramabad, Iran in 2012-2013 cropping season. Evaluated traits were: day to maturity, day to pollination, grain filling rate, grain ...

Facilitate the selection procedure to improve performance of new genotypes of rice is essential. In present study in order to evaluate relationship between grain yields with other agronomic traits, a global rice collection including 100 accessions was seeded in an incomplete block design (triple lattice 10×10). Afterward, grain yield and 14 morphological traits were evaluated. Correlation coeff...

Development of germplasm resources through importing new genotypes could improve the efficiency of safflower (Carthamus tinctorius L.) breeding programs. During 2014-2015 season, 82 imported safflower genotypes were evaluated in randomized complete block design at the research station of ORDC (Oilseeds Research & Development Company) in Sari. In this plan, six important quantitative traits rela...

Simplifying the selection procedure to improve yield of new genotypes of rice is necessary. in order to evaluate relationship among grain yield and other agronomic traits, an experiment was conducted in agricultural and natural resoures research center in 2015-2016 year. In present study, 10 rice genotypes were studied in randomized complete blocks design with three replications. Grain yield al...

  Evaluation of genetic improvement of grain yield and other traits in cultivars released in different years is useful to determine plant breeding impact on grain yield improvement, to define future selection criteria and to identify the desirable environment and traits for further assessment. This study was conducted to evaluate the genetic improvement for grain yield and other traits of twelv...

To study relationship between grain yield and important agronomic traits of rapeseed in paddy fields as second culture, fourteen varieties of spring rapeseed were grown in a randomized complete block design of experiment with three replications at Rice Research Institute of Iran, Rasht, during 2005-2006. Analysis of variance showed that there were significant differences between varieties for m...

One way to increase crop yield per unit of area is to close the gap between actual and potential yield in cropping systems. This study was conducted to determine the factors that affeced wheat yield gap in Khorramshahr, Iran during 2018-2019 growing season. In this study 60 fields of different areas under cultivation, field management practices and grain yield yield levels were surveyed based o...

In order to study genetic diversity of different wheat inbred lines and grain yield modeling as well as selection of elite lines, 305 wheat lines derived from Roshan × Falat cultivar along with their parents as well as two check (Mahdavi and Shahpasand) cultivated in research field of Sahid Bahonar university of Kerman in augment design, on growing season of 2013-2014. Result of genetic and phe...
