Abstract:
... Inheritance of an induced bushy mutant (EMS 24-5) of periwinkle (Catharanthus roseus) and its genetic relationship with an earlier reported dwarf mutant (NEU 6-15) was studied by crossing it with its parental variety, Nirmal and the dwarf mutant. The bushy mutant was found to be under the control of a monogenic recessive gene (by), which was inherited independently of the recessive gene (dw ₁ ) in ...

We investigated maturity, average weight per fruit, yield and acceptable yield in the pruning conditions over a period of two planting seasons. The analysis of variance for all of the characteristics indicated ...

Abstract:
... Safflower (Carthamus tinctorius L.) oil with high oleic acid content (>75%) has a great value for both food and non-food uses. The trait has been reported to be environmentally stable and controlled by recessive alleles at one single gene Ol, even though the influence of modifying genes has been suggested. Additionally, germplasm with higher oleic acid content (>85%) has been reported. The objecti ...

Abstract:
... Selecting high yielding upland cotton, Gossypium hirsutum L. lines with improved fiber quality is a primary breeding goal. A diverse set of ten cultivars and one breeding line were crossed in a half diallel. Parents and F₂ hybrids were grown in three environments at Mississippi State, MS. Ten agronomic and fiber traits were analyzed by a mixed linear model approach based on the additive-dominance ...

Abstract:
... The supernumerary spikelet character of bread wheat (Triticum aestivum L.) is an abnormal spike with extra spikelet per spike. Supernumerary spikelet line 51885 was derived from the cross between octoploid Triticale and common wheat Fei 5056. The number of spikelet is over 30, and supernumerary spikelet is genetically stable. The inheritance of supernumerary spikelets in the line 51885 was genetic ...

Abstract:
... Flowering time has biological and agricultural significance for crops. In Upland cotton (Gossypium hirsutum L.), photoperiodic sensitivity is a major obstacle in the utilization of primitive accessions in breeding programs. Quantitative trait loci (QTLs) analysis was conducted in two F₂ populations from the crosses between a day-neutral cultivar Deltapine 61 (DPL61) and two photoperiod sensitive G ...

Abstract:
... Fusarium head blight (FHB) infects all cereals including maize and is considered a major wheat disease, causing yield losses and mycotoxin contamination. This study aimed to compare the realized selection gain from marker and phenotypic selection in European winter wheat. A double cross (DC) combined three FHB resistance donor-QTL alleles (Qfhs.lfl-6AL and Qfhs.lfl-7BS from 'Dream', and one QTL on ...

crops; outbreeding; crossing; quantitative trait loci; epistasis; regression analysis; genotype; prediction; inheritance (genetics)
Abstract:
... Many important crop species are outbreeding. In outbreeding species the search for genes affecting traits is complicated by the fact that in a single cross up to four alleles may be present at each locus. This paper is concerned with the search for interacting quantitative trait loci (QTL) in populations which have been obtained by crossing a number of parents. It will be assumed that the parents ...

Abstract:
... Cowpea is an important legume in sub-Saharan Africa where its protein rich grains are consumed. Insect pests constitute a major constraint to cowpea production. Flower bud thrips (FTh) is the first major pest of cowpea at the reproductive stage and if not controlled with insecticides is capable of reducing grain yield significantly. Information on the inheritance of resistance to FTh is required t ...
