Quantitative genetic analysis of characters in wheat using crosses of chromosome substitution lines (theoretical considerations).
COMPARED to studies based on ordinary homozygous varieties, the use of chromosome substitution lines obtained by means of aneuploid series in Triticum uestiuum L. (SEARS 1944, 1953; UNRAU, PERSON and KUSPIRA 1956; PERSON 1956) permits a more complete, detailed and reliable analysis of the genetic structure of hexaploid wheats (KUSPIRA and UNRAU 1957; SEARS, LOEGERING and RODENHISER 1957; LOEGER...
متن کاملThe location of genetic factors controlling a number of quantitative characters in wheat.
technique for the location of genetic factors in the hexaploid wheat, Triticum A aestiuum (2n = 6x = 42), has been described in an earlier paper (LAW 1966). This technique exploited an inter-varietal chromosome-substitution line in which a single homologous pair of chromosomes in a recipient variety has been replaced by its homologues from a donor variety (SEARS 1953). By using this type of gen...
متن کاملIdentifying Quantitative Trait Loci in Experimental Crosses Committee in Charge: Identifying Quantitative Trait Loci in Experimental Crosses
Identifying quantitative trait loci in experimental crosses Identifying the genetic loci responsible for variation in traits which are quantitative in nature (such as the yield from an agricultural crop or the number of abdominal bristles on a fruit y) is a problem of great importance to biologists. The number and eeects of such loci help us to understand the biochemical basis of these traits, ...
متن کاملDevelopment of yellow rust resistant doubled haploid lines of wheat through wheat ´ maize Crosses
In order to produce doubled haploid lines of bread wheat resistant to strip or yellow rust, three F1 wheat hybrids were crossed using pollens of three maize hybrids. Out of 1071 pollinated florets, success in seed set ranged from 63.1% to 93.3% (mean 78%). Differences in seed set among the crosses were not significant. Embryo formation in the seeds developed on different crosses also varied fro...
متن کاملPopulation structure and quantitative characters.
A migration matrix model is used to investigate the behavior of neutral polygenic characters in subdivided populations. It is shown that gametic disequilibrium has a large effect on the variance among groups but none at all on its expectation. The variance of among-group variance is substantial and does not depend on the number of loci contributing to variance in the character. It is just as la...
