چکیده
A review of previous studies is presented on estimates of genetic parameters and responses to selection with traditional breeding approaches, on correlations between agonistic behavior and growth performance, and on theoretical frameworks for selection incorporating interactions among individuals and on practical methods for incorporating competition effects in breeding programs.

A Review on Production of Glyphosate-Resistant Plants with Emphasis on Molecular Methods
Herbicide-resistant plants are one of the most common plants that comprise the majority of the total population of transgenic plants. Glyphosate is an herbicide that controls a wide range of plant species. Position of these herbicides reaction is 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) that only exists in plants and some bacteria. This herbicide was known to be suitable and safe for...
متن کاملA brief review on chemical agents involved in chromosomal aberrations in military wars
Chromosomal abnormalities are able to produce genetic instability, which is the main cause of many diseases. Cytogenetics is analysis of any kind of chromosomal abnormalities. Chromosomal alterations can be divided into structural and numerical abnormalities, both of which play a significant role in the development of many diseases, particularly cancer. Today, most cytogenetic analyzes are perf...
متن کاملGenetic diversity analysis of recombinant inbred lines of rice (Oryza sativa L.) using microsatellite markers
Estimation of genetic diversity is an important factor in germplasm conservation and characterization. In rice breeding programs, genetic diversity information on specific regions of genome can be very useful for the application of marker assisted selection (MAS) and for gene mapping. A total of 152 rice lines were considered for breeding programs using microsatellites (SSR) technique. The tota...
متن کاملStudy on Combining Ability and Gene Effects Estimation in Some Sweet Corn Inbred Lines (Zea mays L. var saccarata) by Line × Tester Method
In breeding programs determination of gene effects and general and specific combining ability for screening of test crosses is necessary. In order to estimate the genetic variance components and the general and specific combining ability of sweet corn lines, an experiment was conducted using 8 sweet corn S6 inbred lines (including 4 maternal and 4 paternal lines) by line × tester mating design ...
متن کاملSeed dormancy: A Review on Importance, Dormancy Types and Elimination Methods, with Emphasis on the Trend of Seed Dormancy Research in Iran
Extended Abstract Introduction: Seeds need successful germination at the optimal time and conditions to survive. Sometimes, even in the best environmental and genetic conditions of the seed, they do not germinate or germinate with a delay, which are called dormant seeds. Seed dormancy can have positive effects on avoiding adverse conditions and ensuring survival in the environment. However, do...
