We report on results of a trawl survey to assess the abundance of Batoid fish resources in the Oman Sea. The catch per unit area CPUA as the main index was estimated. The objectives of this study were to determine the catch composition and distribution pattern of Batoid fishes in the study area and in different depth strata of the Oman Sea.A total of 82stations were randomly selected 2012. The ...

This experiment was conducted at the Agricultural Research Farm of Isfahan University of Technology in 2006 to evaluate the effects of row spacing and plant distance on the row on yield and yield components of sunflower, Hisun-36 hybrid. A split plot layout was used with a randomized complete blocks design and three replications. Row spacing (60 and 75 cm) was the main plot and plant distance o...

     To estimate heritability and association between traits traits, 148 recombinant inbred lines and their parents (Yecora Rojo and No. 49) were evaluated in Alfa lattice design with two replications under normal and water deficit conditions during two cropping season (2013-15). Results showed that there were significant differences between genotypes for all studied traits. The estimated herit...

ABSTRACT- Barley (Hordeumvulgare L.) is one of the most important cereals in the world which is used as human and cattle feed and for malt production. One of the most important steps in a hybrid and selection breeding program of barley is the selection of suitable parents with high general (GCA) and specific combining ability (SCA) for grain yield. In order to estimate the combining ability and...

Half diallel crosses of eight bread wheat cultivars were used to estimate the genetic parameters and types of genetic control for yield and yield components, and to determine the effects of environmental factors on these parameters. Parents and their F2 hybrids were grown in a randomized block design under irrigated and stressed (terminal drought) conditions. For all traits, except for number o...

Scarcity of water for irrigation is an alarming issue of Pakistan and the problem is being magnified rapidly with the passage of time. Shortage of water is thus, a limiting factor in increasing per unit area wheat (Triticum aestivum L.) yield that is staple food of most of the people. Eventually, the gap between production and consumption is widening day by day and Pakistan is now suffering fro...
