determination of cardinal temperatures during seed germination and emergence as well as the thermal time requirement for each stage is essential in crop management and modeling of plant growth and development. two experiments were conducted to predict cardinal temperatures and thermal time requirement for germination and emergence of chickpea genotypes. in the first experiment, seed germination...

HE general model underlying all methods of quantitative inheritance analysis T asserts that in any genetic population consisting of a mixture of genotypes the population frequency distribution of phenotypes is a corresponding mixture of the individual phenotypic distributions associated with each of the genotypes. Thus, if G is a genetic population consisting of the n different genotypes gl , g...

Background: To study methaemoglobin content and NADH-methaemoglobin reductase activity of three human erythrocyte genotypes (HbAA, HbAS and HbSS).Materials and Methods: Studies to ascertain methaemoglobin concentration and level of NADH-methaemoglobin reductase activity of three human erythrocyte genotypes (HbAA, HbAS and HbSS) were carried out in forty-three (43) healthy male participants of c...

self-incompatibility is one of the most important difficulties in almond production which reduce fruit set dramatically.therefore, breeding almond to produce self-compatible genotypes is very important. in this research, pollen tube growth was studied in 28 genotypes obtained from crossing between touno (male parent) and shahrood 12 (female parent) after self pollination by fluorescent microsco...

sugar beetis an essentially self-sterile plant for which the vegetative propagation is used to obtain identical sister plants. sugar beet micropropagation is initiated by meristematic cuttings. sugar beet meristematic flower stalk explants were established in sterile cultures and used for shoot propagation. two pgob medium with different hormonal combinations: 1) ba/naa/iba at 1, 0.1 and 0.1 an...

An algebraic model is presented for selection by the mating advantage of rare genotypes. In accordance with the results of recent experiments, the selective advantage is formulated as inversely proportional to genotype frequency. The model applies to any number of alleles at an autosomal locus or at a sex-linked locus, and it provides for a different intensity of selection for each genotype in ...
