a 7×7 complete diallel cross experiment was performed to study the genetic relationships of grain yield and some agronomic traits in rice. analysis of variance showed significant differences among genotypes for all traits. results of correlation analysis showed that rice grain yield was positively and significantly correlated with by (rp = 0.81, rg =0.55), hi (rp =0.35, rg =0.79), np (rp = 0.80...

Dairy cattle breeding programs have been based in the selection for traits related to milk production. In this research a data set of 63 herds of East Azerbaijan province Holstein cattle, collected during 2002-2013 by the Iranian Animal Breeding Center was used to estimate the repeatability and heritability of three traits of economic importance. Genetic parameters for first three lactations of...

  This research was conducted in order to determine the relationship between grain yield and yield components, using 30 common bean varieties in a randomized complete block design with four replications at the Agricultural filed faculty of Agriculture,Tehran university In this study 18 traits were assessed on 10 random plants from each plot. The result showed that there were significant differe...

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-...

Wheat (Triticum aestivum L.) is widely cultivated in the Mediterranean zone where plantsgenerally suffer from water stress during heading and reproductive stages. This research wascarried out at the experimental farm of the faculty of agriculture, Kafrelsheikh University usingtwo water treatments (water stress and well-watered), four N levels (0, 80, 160 and 240 kg ha-1)and two ascorbic acid le...

For evaluation of the traits related to water deficit stress in 20 spring wheat (Triticum aestivum L.) cultivars and subsequently  determination of the most tolerant and sensitive cultivars, an experiment was carried out in split plot based on randomized complete block design (RCBD) in the research farm of the University of Tabriz, Iran during 2010-2011 and 2011-2012 crop seasons. The first fac...

to study and determine  effect of salinity on relationship between  agronomic  characteristics and grain yield, 167  of  the  seri/babax recombinant wheat inbred  lines (ril) together with two parents were evaluated using alpha latice design with two replications under two conditions (salt stress and normal), in zabol field station in 2011-12 cropping season. fourteen  traits  including: some a...

Drought tolerance (DT) and drought avoidance (DA) are two major mechanisms in drought resistance of higher plants. In this study, the genetic bases of DT and DA at reproductive stage in rice were analyzed using a recombinant inbred line population from a cross between an indica lowland and a tropical japonica upland cultivar. The plants were grown individually in PVC pipes and two cycles of dro...
