Association Analysis of Charcoal Rot Disease Resistance in Soybean
Ghorbanipour, Ali,Rabiei, Babak,Rahmanpour, Siamak,Khodaparast, Seyed Akbar The Korean Society of Plant Pathology 2019 Plant Pathology Journal Vol.35 No.3
In this research, the relationships among the 31 microsatellite markers with charcoal rot disease resistance related indices in 130 different soybean cultivars and lines were evaluated using association analysis based on the general linear model (GLM) and the mixed linear model (MLM) by the Structure and Tassel software. The results of microsatellite markers showed that the genetic structure of the studied population has three subpopulations (K=3) which the results of bar plat also confirmed it. In association analysis based on GLM and MLM models, 31 and 35 loci showed significant relationships with the evaluated traits, respectively, and confirmed considerable variation of the studied traits. The identified markers related to some of the studied traits were the same which can probably be due to pleiotropic effects or tight linkage among the genomic regions controlling these traits. Some of these relationships were including, the relationship between Sat_252 marker with amount of charcoal rot disease, Satt359, Satt190 and Sat_169 markers with number of microsclerota in stem, amount of charcoal rot disease and severity of charcoal rot disease, Sat_416 marker with number of microsclerota in stem and amount of charcoal rot disease and the Satt460 marker with number of microsclerota in stem and severity of charcoal rot disease. The results of this research and the linked microsatellite markers with the charcoal rot disease-related characteristics can be used to identify the suitable parents and to improve the soybean population in future breeding programs.

Effects of Low Temperature and GA₃ on Quality of Cut Flowers of Narcissus jonquilla ‘German’
Zeynab Roein,Moazzam Hassanpour Asil,Babak Rabiei 한국원예학회 2008 Horticulture, Environment, and Biotechnology Vol.49 No.5
In this study, the effects of low temperature and GA3 were investigated on the bulb forcing and quality of Narcissus. Temperature and GA3 were studied in two (4℃ for 12 weeks and 23℃) and four (0, 200, 400 and 600 ppm) levels, respectively. The experiment was performed at Faculty of Agricultural Sciences, University of Guilan, Rasht, Iran, in 2006. The results indicated that sprouting occurred faster (9.34 days) in bulbs treated for 12 weeks at 4℃ than those non chilled (34.34 days). Moreover, low temperature treatment reduced flowering time (37.06 days). Vase life was much shorter in chilled bulbs than none chilled. GA3 reduced the sprouting period more than control treatment (0 ppm), so with increasing GA₃ concentration, sprouting was decreased (r² = 0.74). However, the effects of GA₃ on the flowering time and quality of flowers were not significant. Temperature × GA₃ interaction was not significant on the all studied traits. Results from this study showed that chilling of Narcissus bulbs prior to planting may be used as an effective treatment to overcome dormancy and promote uniformity in bulbs sprouting.

Silver Thiosulphate in Relation to Vase Life of Narcissus Cut Flowers (Narcissus jonquilla)
Zeynab Roein,Moazzam Hassanpour Asil1,Babak Rabiei 한국원예학회 2009 Horticulture, Environment, and Biotechnology Vol.50 No.4
Narcissus is one of the cut flowers which postharvest problems cause loss of quality and shorter vase life. In this research, silver thiosulphate (STS) was used for improving quality and vase life of cut flowers. The flowers were harvested at the goose neck stage and pulsed in the different concentrations of STS (control treated with distilled water, 0.2, and 0.4 mM) for 24 hours. Results showed that the 0.2 mM STS was the best treatment and increased vase life of narcissus cut flowers to 10 days. After the short period of treatment, concentration of 0.4 mM STS caused severe burning of the tepals and was toxic. The 0.4 mM treatment slightly reduced the rate of senescence of flowers. Also, results showed that there was positive relationship between the fresh weight and water uptake with longevity of narcissus cut flower.

Dominant Variance Has an Important Role in Downy Mildew Resistance in Cucumber
Jamal-Ali Olfati,Habibollah Samizadeh,Gholam-Ali Peyvast,S. Akbar Khodaparast,Babak Rabiei 한국원예학회 2011 Horticulture, Environment, and Biotechnology Vol.52 No.4
Downy mildew inflicts severe damage on cucurbits in humid areas of production throughout the world. The genetics of resistance to downy mildew (Pseudoperonospora cubensis) in the cucumber (Cucumis sativus L.) was studied by the means of a half diallel table between 6 inbred lines. Decomposition of dominance variation indicated that the dominance effect was not unidirectional and that dominant genes were not uniformly distributed among the parents. These facts were confirmed and using a further detailed Hayman’s graphical analysis. Narrow-sense heritability estimates were 0.42 so the breeders are able to use selection for this trait. In other hands the heterosis in some crosses was high so breeders are able to use specific cross to produce hybrid with high level resistance.
