Partial Diallel Crosses
A diallel cross is a set of all possible matings between several genotypes, which may be individuals, clones, homozygous lines, etc. Such crosses are used to estimate general and specific combining abilities of lines and crosses respectively. For ‘n’ inbreed lines, the possible F1’s are n(n–1)/2, which are to be tested in a suitably replicated randomized design. With facilities available for te...
متن کاملVariability and inbreeding in semiexotic maize populations.
Three semiexotic populations (CRE-01, CRE-02, CRE-03) obtained by incorporation of exotic germplasm (lines from CIMMYT, Colombia; selected for resistance to corn stunt complex) were evaluated in two cycles of recurrent selection with half-sib families. In cycle-I, samples comprising 50, 70, and 50 half-sib families were evaluated at Jataí (GO) and traits analyzed were ear yield, plant height, a...
متن کاملBiplot Analysis of diallel crosses for yield and some morphological traits in durum wheat
Six varieties of durum wheat were included in a full diallel mating design during 2003-2004 and 2004-2005 cropping seasons in the farm of Maragheh Dryland Agricultural Research Institute (DARI), Iran. Parental durum wheat genotypes and their complete diallel progenies were grown in a randomized complete block design with two replications in the growing seasons of 2005-06. The highest values of ...
متن کاملThe Theory and Analysis of Diallel Crosses.
T H E diallel cross method of investigating the genetical properties of a group of homozygous lines has recently received much attention. HULL (1945) has considered some aspects of the method. A short summary of a more general approach by JINKS and HAYMAN (1953) and its application to several published sets of maize data has also appeared. In another paper JINKS (1954) has described experiments...
متن کاملOptimal Designs for Best Linear Unbiased Prediction in Diallel Crosses
Most of the available results on optimal block designs for diallel crosses are based on standard linear model assumptions where the general combining ability effects are taken as fixed. In many practical situations, this assumption may not be tenable since often one studies only a sample of inbred lines from a possibly large (hypothetical) population. Recently Ghosh and Das (2003) proposed a ra...
