in order to estimate heritability, heterosis, general and specific combining ability and relationships between them in traits of fruit number per plant, days to the first fruit harvest, yield per plant, average fruit weight and rind thickness, seven local populations of iranian melon (‘tashkandi’, ‘khatouni’, ‘garmak’, ‘aran1’, ‘mirpanji’, ‘suski-e-sabz’ and ‘golpaygan’) were crossed using a co...
In bread wheat (Triticum aestivum L.), crop height is an important determinant of agronomic performance. To map QTLs with additive effects and additive×additive epistatic interactions, 148 recombinant inbred lines and their parents, (‘YecoraRojo’ and Iranian landrace (No. #49)) were evaluated under normal and water deficit conditions. The experiments were carried out on research farms of Mahaba...
Directional selection produces a change in the population mean of a phenotype, but this shift will only be translated into a phenotypic difference between generations if the trait is heritable, in the sense that there is additive genetic variance in the trait. Thus any study of evolutionary change must concern itself both with the factors causing phenotypic change and the genetic architecture o...
Fruit shape index (round shape) and seed size have important effects on pumpkin yield. To investigate these traits to create the most desirable state, a cross was made between two cultivars. This study aimed estimate main gene (additive, dominant di-genic epistasis) determine mode of inheritance for fruit by generation mean analysis. Six generations, namely P1, P2, F1, F2, BC1, BC2 from Zucchin...
In this study, three commercial fresh bean cultivars (SF08/03, Ribera and Java) two pole-type lines (Mor Toparlak Beyaz Toparlak) were hybridized (20 hybrid combinations) in accordance with full-diallel analysis method 2016. F 1 generations parents grown fully-automated plant breeding greenhouse of Selcuk University 2017. Measurements, counts, weightings analyses formed to determine height, pod...
We investigated inheritance of resistance to Pepper yellow mosaic virus (PepYMV) in Capsicum baccatum var. pendulum accessions UENF 1616 (susceptible) crossed with UENF 1732 (resistant). Plants from generations P1, P2, F1, F2, BC1:1, and BC1:2 were inoculated and the symptoms were evaluated for 25 days. Subsequently, an area under the disease progress curve was calculated and subjected to gener...
Migraine frequently co-occurs with depression. Using a large sample of Australian twin pairs, we aimed to characterize the extent to which shared genetic factors underlie these two disorders. Migraine was classified using three diagnostic measures, including self-reported migraine, the ID migraine™ screening tool, or migraine without aura (MO) and migraine with aura (MA) based on International ...
Abstract Nut shape is an important trait in determining the value of a pecan ( Carya illinoensis ) nut crop. influences attractiveness to consumers, filling, ease mechanical cracking, and distinctive enough that it primary means cultivar identification. Narrow sense heritability (h 2 fraction phenotypic variance attributed variation genes with additive effect. Estimation h key breeding programs...
