Efficiently tracking selection in a multiparental population: the case of earliness in wheat.
Multiparental populations are innovative tools for fine mapping large numbers of loci. Here we explored the application of a wheat Multiparent Advanced Generation Inter-Cross (MAGIC) population for QTL mapping. This population was created by 12 generations of free recombination among 60 founder lines, following modification of the mating system from strict selfing to strict outcrossing using th...
متن کاملTen Cycles of Recurrent Selection for Fruit Yield, Earliness, and Quality Three Slicing Cucumber Populations
Fruit yield, earliness, and quality have low to moderate heritability, but are traits of major importance in cucumber (Cucumis sativus L.). The objective of this study was to determine the changes made in those traits using recurrent selection in three slicing cucumber populations (NCMBS, NCES1, and NCBA1). During population improvement, one or two replications of 200 to 335 half-sib families w...
متن کاملEfficiency of Pedigree Selection in Bread Wheat under Drought Stress Conditions . I . Morphological traits
Pedigree selection was practiced on two bread wheat populations, namely Debeira x Sahel 1 and Sids 6 x Sahel 1as a first and second population, respectively under drought stress conditions (at 12 % soil moisture content) in order to improve some morphological traits (plant height, spike length, no. of spikelets /spike and days to maturity). The obtained results revealed that all F3 families in ...
متن کاملPredation in two species of leech under laboratory conditions
Two 60 day experiments on predation behavior of leeches were conducted concurrently. In the first, medicinal leeches, Hirudo orientalis (Utevsky and Trontelj, 2005) were fed to satiation on bovine blood and subsequently transferred into two large opaque plastic containers of equal size but with differing temperatures, 6-7?C and 23-24?C, containing starved Erpobdella octoculata (L.). At the high...
متن کاملA method for bubble volume measurement under constant flow conditions in gas–liquid two-phase flow
Measuring the volume of a bubble, especially at its detachment, is a basic subject in gas-liquid two-phase flow research. A new indirect method for this measurement under constant flow conditions is presented. An electronic device is designed and constructed based on laser beam intensity. This device calculates the frequency of the bubble formation by measuring the total time of the formation p...
