evaluation of genetic diversity, heritability and genetic progress in kabuli type chickpea genotypes
to study breeding resource of kabuli chickpea lines of national plant gene bank of iran, two separate experiments were conducted during 2010 and 2011. in this study, 57 lines of kabuli type chickpeas- selected from primary evaluation experiments, out of 1500 accessions were planted at farm of seed and plant improvement research institute in karaj, iran, according a randomized complete block des...
Genomics-assisted breeding methods have been rapidly developed with novel technologies such as next-generation sequencing, genomic selection and genome-wide association study. However, phenotyping is still time consuming and is a serious bottleneck in genomics-assisted breeding. In this study, we established a high-throughput phenotyping system for sorghum plant height and its response to nitro...
Over the past 50 years, thousands of rice varieties have been introduced by plant breeders to agricultural communities all over the world. Despite the improvement of attributes such as grain yield and tolerance to biotic and abiotic stresses, a significant portion of farmers still prefer local varieties over the improved cultivars. The main reasons for this perference are the absence of a dire...
In quantitative genetics, computer simulation is commonly used to evaluate alternative plant breeding strateFunctional genomics is the systematic study of genome-wide effects gies on the basis of stochastic descriptions of gene action of gene expression on organism growth and development with the ultimate aim of understanding how networks of genes influence traits. and interaction (e.g., Hospit...
Application of Molecular Genetics in livestock production has been reviewed indicating that why molecular genetics is important in the presence of conventional livestock improvement programs. Molecular genetic technologies like marker assisted selection, PCR, DNA sequencing, tran genesis and cloning have been discussed. The paper includes the applications of Molecular biotechnologies in animal ...
Plant breeding programs in local regions may have genetic and phenotypic variations that are desirable and shape adaptability during the establishment of local populations. Despite the characterization of genetic population structures in various kinds of populations, the effects of variations in phenotype on agro-economical traits currently remain unclear. In the present study, we evaluated phe...
Infectious and parasitic diseases generate large economic losses in salmon farming. A feasible and sustainable alternative to prevent disease outbreaks may be represented by genetic improvement for disease resistance. To include disease resistance into the breeding goal, prior knowledge of the levels of genetic variation for these traits is required. Furthermore, the information from the geneti...
مطالعه تنوع ژنتیکی صفات مرتبط با عملکرد دانه در ژرم پلاسم داخلی و خارجی گلرنگ (Carthamus tinctorius)
Safflower (Carthamus tinctorius L.) is cultivated in a wide range of geographical conditions in the world from Africa to Europe, India and China. Previous studies have shown that diversity in indigenous Iranian germplasm is limited for some traits therefore germplasm collections from other origins need to be considered. An experiment was conducted to evaluate agronomic and morphological traits ...
As one of the essential cereal crops, wheat provides 20% calories and proteins consumed by humans. Due to population expansion, dietary shift climate change, it is challenging for breeders develop new varieties meeting production requirements. Marker-assisted selection (MAS) has distinct advantages over conventional in plant breeding, such as being time-saving, cost-effective goal-oriented. Thi...
Software was developed to predict selection responses and rates of inbreeding from livestock breeding programs. Variance components are needed as input for the program, which subsequently enables the user to evaluate various breeding program designs. Consequently, breeding program structures with discrete (e.g., fish or poultry breeding) or overlapping generations (e.g., pig or cattle breeding)...
