The present study was performed to classify and study genetic diversity between Calotropis procera accessions from different regions of Kerman province (Iran) using ISSR markers. In total, DNA from 14 plant samples with nine ISSR primers was amplified by PCR and their banding pattern was obtained. The primers showed acceptable polymorphism (35.93) and minimum and maximum polymorphic information...

Body weight (BW) records (n=11,659) of 4961 Kurdi sheep from 215 sires and 2085 dams were used to estimate the additive genetic, direct and maternal permanent environmental effects on growth from 1 to 300 days of age. The data were collected from 1993 to 2015 at a breeding station in North Khorasan province; Iran. Genetic parameters for growth traits were estimated using random regression test-...

Fenugreek is one of the important edible and medicinal vegetables that have a long history of cultivation and consumption. Characterize the extent of the genetic diversity among landraces will provide a good context for future breeding programs and genetic resource preservation. Genetic diversity and population structure of 88 individuals of eight landraces of Iranian fenugreek evaluated based ...

In this study, selection strategies were simulated to find optimal selection strategy in Japanese quails. Breeding goal was consisted of body weight and egg weight traits. Effects of using genetic markers related to carcass weight were investigated by five different selection strategies. In this case, breeding goal included body weight, egg weight and carcass weight. Deterministic simulation, b...

A bstract. A formalism recently int roduced [4, 5] uses the met hods of statist ical mech anics to mod el the dynamics of gene t ic algor it hms (GAs) . To be of mor e general int erest this formalism must be able to descr ibe problems ot her th an the tes t cases cons idered in [5]. In this pap er , the technique is applied to th e subset sum prob lem , which is a combinatorial optimizat ion p...

An algor i thm is descr ibed which is capable of solving cer ta in word problems: i .e . of deciding whether or not two words composed of var iables and operators can be proved equal as a consequence of a given set of identities satisf ied by the opera tors . Al though the genera l word problem is wel l known to be unsolvable, this algorithm provides results in many interesting cases. For examp...

The classification of bamboos based on floral morphology and reproductive characters is very hard due to erratic flowering behavior and unusually long reproductive cycle. The application of reliable and effective DNA molecular markers is highly essential to address this problem. In the present investigation, inter-simple sequence repeats (ISSR) markers were employed to study phylogenetic relati...

Twenty-two G. glabra populations were used to study the genetic diversity of ISSR molecular markers. 12 primers were used to amplification of genomic DNA fragments of G. glabra populations. High genetic diversity based on ISSR markers was observed among individuals. A total of 130 bands were formed and 105 bands were polymorphic. The mean polymorphism percentage among studied populations was 80...
