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...

An experiment was conducted at Rasht Rice Research Institute, in 2001 to study trait relationships and to determine the direct and indirect effects of different characteristics on grain yield of rice (Orgza sativa L.). A 9x2 factorial experiment in complete randomized block design with 3 replications was used. The two factors were 9 cultivars, namely: Hashemi, Ali Kazemi, Binam, Sepeedroud, Nem...

In order to study the effect of terminal drought stress on yield and yield components and some physiological traits of wheat genotypes, a field experiment was conducted at the Research Farm of Agricultural College of Shiraz University during 2010-11 growing season in a split plot arrangement based on randomized complete block design with three replications. Main plots were assigned to irrigatio...

In order to investigate path analysis and study correlations among 16 agronomic traits, 49 Iranian and foreign rice entries were evaluated in a simple lattice square as experimental design with 2 replications at research farm of Tonekabon agricultural college in 2001. Analysis of variance showed significant difference among genotypes for all the studied traits (p<0.05). Phenotypic and genotypic...

This study was conducted to analyze the correlation among grain yield, yield components, duration of vegetative and grain filling periods in twelve oat (Avena sativa L.) cultivars at the Research Farm of the College of Agriculture, Isfahan University of Technology, from 2001 to 2003. A randomized complete block design with three replications was used. The correlation coefficients among the grai...

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...
