Thirty soybean cultivars from different maturity groups were evaluated in a randomized complete block design with four replications in Research Station of College of Agriculture at Tehran University in Karaj in 2004. The purpose was to determine genetic relationship of some important agronomic traits related to seed yield. Analysis of variance showed that there were significant differences amon...

The present study was conducted to investigate the genetic diversity and evaluate the drought tolerance indices on 16 genotypes of faba been based on split plot design with three replications in Agricultural Research Center of Borujerd. Irrigation regimes as the including normal and drought stress levels and genotypes were considered as the main and sub plot,respectively. Analysis of variance f...

This study was conducted in Research Farm of Isfahan University of Technology to evaluate some of the agronomic and physiological traits and grain yield potentials of ten bread wheat cultivars using a split plot design with three replications. Main and sub plot consisted of optimum and stress moisture treatments (irrigation after 70±3 and 130±3 mm evaporation from class A pan) and wheat cultiva...

Sainfoin in believed as an important forage crop regarding its suitable agronomical characteristics and feeding livestock. Evaluation of general combining ability is a critical preliminary stage before selection of suitable parent and production of synthetic varieties. Thirty six sainfoin landraces which have been collected from different parts of Iran were grown in 2000 in a randomized complet...

Selection for drought tolerance typically involves evaluating genotypes for either high yield potential or stable performance under drought stress. In order to select drought tolerant land races of bread wheat an experiment was conducted in a randomized complete block design (RCBD) with three replications under two different rainfed and irrigated conditions during the growing season 2010-2011. ...

Canola (Brassica napus), with its prominent yellow flowers, has unique spectral characteristics and necessitates special indices to quantify the flowers. This study investigated four for high-resolution RGB images segmenting flower pixels. The compared vegetation digitally canola area develop a seed yield prediction model. A small plot (2.75 m × 6 m) experiment was conducted at Kernen Research ...

In order to study seed yield and seed yield components in bean under reduced irrigation condition and assessment drought tolerance of genotypes, 15 lines of White beans were evaluated in two separate RCB design with 3 replications under stress and non stress conditions. Analysis of variance showed that there were significant differences among varieties in terms of traits under study, indicating...
