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 کاملSoybean seed composition in cultivars differing in resistance to charcoal rot ( Macrophomina phaseolina)
Seed composition in soybean [Glycine max (L) Merr.] has not been well investigated under charcoal rot infestation under irrigated and non-irrigated conditions. The objective of the present experiment was to assess seed composition and nitrogen fixation under these conditions. No significant differences in protein levels in the moderately resistant germplasm line DT97-4290 were observed under th...
متن کاملMacrophomina phaseolina as causal agent for ch rot of sunflower
Macrophomina phaseolina has a wide host range and is responsible for causing losses on m cultivated and wild plant species. So far in Pakistan it has been reported to cause disease on hosts including field crops, pulses, flowers and vegetable have been reported. Infection on s first reported from Sri Lanka in 1927 and in 1982 it was reported from sunflower field in fungus is reported to be soil...
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 کاملGenetic Architecture of Charcoal Rot (Macrophomina phaseolina) Resistance in Soybean Revealed Using a Diverse Panel
Charcoal rot (CR) disease caused by Macrophomina phaseolina is responsible for significant yield losses in soybean production. Among the methods available for controlling this disease, breeding for resistance is the most promising. Progress in breeding efforts has been slow due to the insufficient information available on the genetic mechanisms related to resistance. Genome-wide association stu...
