Selection theory for marker-assisted backcrossing.
Marker-assisted backcrossing is routinely applied in breeding programs for gene introgression. While selection theory is the most important tool for the design of breeding programs for improvement of quantitative characters, no general selection theory is available for marker-assisted backcrossing. In this treatise, we develop a theory for marker-assisted selection for the proportion of the gen...
متن کاملMarker-assisted Backcrossing for Identification of Salt Tolerant Rice Lines
SSR or microsatellite markers are proved to be ideal for making genetic maps, assisting selection and studying genetic diversity in germplasm. SSR markers are playing important role to identify gene for salt tolerance that can be helpful for plant breeders to develop new cultivars. The experiment was conducted during the period from July 2009 to November 2010 in the experimental field and Biote...
متن کاملMarker-assisted backcrossing: a useful method for rice improvement
The world's population is increasing very rapidly, reducing the cultivable land of rice, decreasing table water, emerging new diseases and pests, and the climate changes are major issues that must be addressed to researchers to develop sustainable crop varieties with resistance to biotic and abiotic stresses. However, recent scientific discoveries and advances particularly in genetics, genomics...
متن کاملEvaluation of Drought Tolerance in Barley Genotypes (Hordeum vulgare L.) using Drought Tolerance Indices
Extended Abstract Introduction and Objective: Drought stress is one of the most important factors in reducing yield and barley production in rainfed arid regions, and counteracting or reducing the effect of stresses as a useful solution to increase barley yield. Therefore, improvement of stress-tolerant and suitable barley cultivars for arid and semi-arid regions is essential. Material and Me...
متن کاملIdentification and evaluation of HvPIP1; 4 and HvnsLTP genes expression for drought tolerance in barley
It is of great significance to understand the tolerance mechanisms by which plants deal with drought stress and application of these mechanisms for improvement of genotypes in response to drought stress. In order to identify and investigate the expression of genes involved in tolerance to drought stress, leaf and root EST were analyzed in Spontaneum (wild barley) and Nimruz (tolernt to drought ...
