A Physiological Approach to Breeding for Environment
نویسندگان
چکیده
Huisman, Van Vliet and Sebens (1958) reported a difference between the oxygen dissociation curves of the two sheep haemoglobins and suggested that natural selection would favour haemoglobin A at high altitudes. They also postulated an advantage for Hb B at sea level. The difference in oxygen dissociation curves has been confirmed (Dawson and Evans 1962; Naughton et al. 1963;. Sirs 1966). Dawson and Evans (1962) reported that within either haemoglobin type the oxygen dissociation curve of the HK cells is to the left of that of the low potassium (LK) cells.

Genetic analysis of Biochemical and Physiological Traits using Haymen’s Graphical Approach in Lines and F2 Progenies of Maize (Zea mays L.)
The diallel mating design is an important tool used by plant breeding programs to obtain information on trait inheritance. Knowledge of gene action, heritability and genetic advance from selection is a prerequisite for starting a breeding program for developing varieties of maize. Five maize S7 lines and their F2 progenies were studied in a 5 × 5 half-diallel crossing design to evaluate the gen...
متن کاملUse of Restricted Maximum Likelihood Approach for Estimation of Genotypic Correlation and Heritability in Bread Wheat (Triticum aestivum L.) Under Water Deficit Stress
Wheat is mostly cultivated at rainfed condition in Iran, so, water deficit stress has much effect on yield reduction. Hence, breeding activities are necessary for introduction of wheat tolerant genotypes to water deficit stress. In order to estimate the heritability and genetic correlation between traits of 36 wheat genotypes, an experiment was conducted in two separate conditions (water stress...

Dehydration is the most important limiting factor in agricultural production in arid and semi-arid regions, and water shortages (especially at the reproductive stages) due to lack of precipitation and unequal distribution are inappropriate for limiting the yield. In this research, cross between the Gasspard cultivar (dehydrated susceptible parent) and DN11 line (resistant parent) was performed....

Stomata, the small opening in leaf connecting plant with atmosphere, play pivotal roles in global water and carbon cycles. Stomata regulate the two key important physiological functions viz. photosynthesis and transpiration and thus are crucial for performance of crop species in changing climatic conditions. Although environmental factors influence the density and size of stomata, the genetic c...

Literatures have reported that a lot of drought related genes were cloned and individual gene showed positive effects under controlled stress experiments, but were not much effective in the field. Although, the progresses by conventional breeding approaches were achievable as some drought varieties have been released to the farmers in the recent years but this is not adequate to cope up with th...
