The Rahmat cultivar (Soy 91-19a line) was developed to introduce an early-maturing soybean cultivar for Golestan province. This cultivar originated from the segregating generations of a crossbreeding program between the Charleston (maternal) and Mustang (paternal) cultivars, initiated in 2001. In preliminary yield trials, the Soy 91-19a line was identified as a top performer, producing 3496 kgha-1. In adaptability trials (2013-2014), using GGE biplot analysis and simultaneous selection for yield and stability, the Soy-91-19a line, with an average grain yield of 2739 kgha-1 and a growth period of 117 days, emerged as the best genotype in terms of yield, stability, and earliness, showing a yield increase of 389 kgha-1 compared to the Williams control cultivar. Under farmer conditions in Golestan, this line produced 3198 kgha-1, demonstrating a 21% yield increase over the Williams cultivar. This line is resistant to Phytophthora sudden death (Phytophthora soja) and semi-sensitive to charcoal rot. Additionally, the Soy 91-19a is indeterminate, multi-branched, early-maturing, drought-tolerant, and resistant to lodging and grain shattering. The oleic acid content of this line is 5% higher than that of common cultivars. Due to its high yield and desirable agronomic traits, this line has been introduced as the Rahmat cultivar for summer cultivation in Golestan province.

In the present study macroinvertebrate community of Jajrood River branches was studied. Sampling from branches of Abnik, Zayegan, Lalan and Ahar was conducted in spring and summer of 1393. Benthic invertebrate were collected by Surber sampler (35 × 35 cm) and fixed in 10% formalin. Benthos samples were separated in the laboratory by lifting loop and were identified at genus level. To assess the ecological condition and water quality Hilsenhoff and EPT indices were used. In general, 28 genus and 3 phyla, 5 classes, 9 orders and 24 families were identified in macroinvertebrate community of these rivers. The highest density of benthos was seen in Lalan branch (842 per square meter), in spring and summer. Among the genera found in all branches, except in Ahaar branch, maximum density was seen for Epeorus genus in summer and Baetis genus in spring. Based on analysis of variance (ANOVA) and post hoc LSD test, significnat difference was only seen when benthos population of Ahaar was compared with the other branches (P <0.05).

Hearing loss is the most frequent sensory disorder affecting 1 in 500 neonates with more than 50% of inherited cases. This trait is a very heterogeneous disorder and happens due to genetic or environmental causes or both. More than 46 genes may be involved in non-syndromic hearing loss. Recently, DFNB59 gene has been shown to cause deafness in some Iranian populations. The aim of this study was to determine the role of DFNB59 gene mutations causing deafness in a group of 130 deaf pupils in Fars province.

This descriptive-laboratory based study investigated the frequency of DFNB59 gene mutations using PCR-SSCP/HA strategy.

Two different DFNB59 polymorphism including 874G>A and 793C>G were found in 1 and 9 of 130 patients studied respectively. However, no DFNB59 mutation was identified.

The results of this study shows that the association of DFNB59 mutations with deafness in Fars province is very low.
