Mapping populations for self-fertilizing crop plants

Qtl Mapping and Its Applications in Crop Plants

Fixation of advantageous alleles in partially self-fertilizing populations. The effect of different selection modes.

The expected fixation probability of an advantageous allele was examined in a partially self-fertilizing hermaphroditic plant species using the diffusion approximation. The selective advantage of the advantageous allele was assumed to be increased viability, increased fecundity, or an increase in male fitness. The mode of selection, as well as the selfing rate, the population size, and the domi...

Biofortification of Crop Plants

Salt resistant crop plants.

Soil salinity is a major constraint to agriculture. To improve salinity tolerance of crops, various traits can be incorporated, including ion exclusion, osmotic tolerance and tissue tolerance. We review the roles of a range of genes involved in salt tolerance traits. Different tissues and cells are adapted for specific and often diverse function, so it is important to express the genes in speci...

Biometrical Parameters of Self-fertilizing Diploid Populations1

HE theoretical aspects of diploid populations where all reproduction is by self-fertilization have been considered by several workers (ANDERSON and KEMPTHORNE 1954; COCKERHAM 1954,1963 ; HORNER, COMSTOCK and ROBINSON 1954; DEMPSTER 1955; KEMPTHORNE 1956, 1957, 1963; HORNER and WEBER 1956; GATES, COMSTOCK and ROBINSON 1957; HANSON and WEBER 1961). Several of these papers have indicated parametri...
