The relationship between some important morphological traits with seed yield in 18 soybean genotypes inclusive three cultivars (JK, May and Cap) and 15 M4 mutant lines were investigated using randomized complete block design with four replications. Results of analysis of variance indicated that there were significant differences between genotypes in all traits except the number of branches per ...

Volatile composition of essential oils from dill, parsley, coriander, and mint were investigated at different harvest dates to determine the most suitable harvest time for each these herbs. Hydrodistillation (HD), using a Deryng system, was used for isolating the essential oils. Isolation and identification of the volatile compounds were performed using gas chromatography-mass spectrometry (GC-...

  Evaluation of genetic improvement of grain yield and other traits in cultivars released in different years is useful to determine plant breeding impact on grain yield improvement, to define future selection criteria and to identify the desirable environment and traits for further assessment. This study was conducted to evaluate the genetic improvement for grain yield and other traits of twelv...

Extended Abstract Introduction and Objective: The cow cockle has a great potential for producing medicinal products due to its triterpenoid saponins. This experiment was aimed to investigate different cow cockle ecotypes under drought stress conditions and select the tolerant ecotype(s) based on agronomic traits using selection indices under different irrigation regimes. Materials and Methods...

Correlation coefficient analysis conducted on 22 triticale x bread wheat derivatives along with six checks to select true- breeding derivative(s) for future hybridization programme with tolerance to drought and cold stress conditions as well as better quality traits revealed significant correlation of grain yield with spikelets per spike, biological yield, harvest index, leaf area index. Intere...

In order to evaluate the effects of plant densities (10, 13, 20 and 40 plant/m2 ) on the yield and yield components of two cultivars (Partow, Gohar) and a line (VC-1973A) of mungbean [Vigna radiata (L.) Wilczek] a field experiment was conducted at the Seed and Plant Improvement Institute (SPII) of Karaj in Summer 1998. This research carried out in a factorial experiment based on Randomized Comp...
