Received ; accepted – 2 – ABSTRACT We present a BeppoSAX observation of the X–ray source AX J0851.9−4617.4 that has been proposed as the neutron star associated to the shell like-supernova remnant RX J0852.0−4622. The image at E>5 keV shows the presence of a new source, SAX J0852.0−4615 , not resolved from AX J0851.9−4617.4 in previous observations. The improved positional accuracy obtained for...

  The most desirable approach to improve characteristics such as yield with polygenic inheritance and genotype × environment interaction, is simultaneous selection using selection index based on related traits. This study was conducted Research Farm of Isfahan University of Technology, to compare selection indices for barley yield improvement under nitrogen stress and non stress conditions, usi...

Sesame is an important oilseed crop in India. To determine potential traits and selection criteria for yield improvement, ninety sesame (Sesamum indicum L.) genotypes were studied in a randomized complete block design with three replications. The data collected on 13 characters were subjected to three different analyses. In variability analysis, high heritability was accompanied by a high genet...

thirty-three M7 soybean mutant lines which originated by γ ray (co-60) from cultivar L17 irradiated with doses150, 200 and 250 Gray (absorbed dose), L17 cultivar and two commercial cultivars Clark (CL) and Williams (WI) were evaluated in view of some agronomical and morphological traits under completely randomized design with three replications. In M7 mutant lines all traits except number of s...

This research was conducted at Research Farm of Isfahan University of Technology to examine the relations among phonologic, morphologic and physiologic traits and their effects on grain yield of 20 oat (Avena sativa L.) genotypes. A randomized complete block design with three replications was used in each irrigation treatment (i.e. irrigation after 70±3, and 130±3 mm evaporation from class A ...

H Harvest index (HI), ratio of seed yield to aboveground dry matter, is a very important parameter for estimating seed yield in several crop models. In this study, the importance, definition, variability and estimation methods of HI in crop models were discussed. HI estimation methods are categorized into two groups including: (i) complex methods that estimate HI from the beginning of seed gro...
