Further, as with naturally selected traits, direct selection for preferences for condition dependent male traits balances out direct selection against female preference due to competition, allowing preference to evolve under lower strengths and higher competition.
This enabled a direct selection for reduced expression under low light conditions by selecting for chlorate-sensitive clones.
This tends to support the view that direct selection for only above-ground organs might also indirectly select for a small root system, especially under well-irrigated and well-fertilized growing conditions, as at CIMMYT breeding stations, where there would be no selection advantage for a larger root system.
Analyses of the GCA for the inbreds shows 4 cross-over interactions between the two temperature treatments indicating that direct selection for heat tolerance will be necessary to increase the response to selection for this trait.
The aim of this study was to compare the genetic response and profit to varying selection strategies that used direct selection for RFI and indirect selection with IGF-1 in association with other traits.
The accuracy of a selection index including only body weight indicated that in this way almost the same amount of the selection response could be achieved compared to what hypothetical direct selection for fillet weight would.
As most of the variation of fillet weight is explained by the variation in body weight and the two traits are highly genetically correlated (0.95 0.96), this allows for efficient indirect selection for fillet weight through direct selection for body weight.
Automated intron design bioinformatics are now available free-of-charge at our website http://clostron.com; the out-sourced construction of re-targeted intron plasmids has become cost-effective as well as rapid; and the combination of constitutive intron expression with direct selection for intron insertions has made mutant isolation trivial.
Selection based on chlorophyll content showed a higher relative efficiency than direct selection for yield in maize (Ziyomo and Bernardo 2013).
However, direct selection for yield under drought in TEs is difficult because of differences in the timing and severity of drought over seasons.
The three seedlots that were genetically improved for growth rate and stem form had not undergone direct selection for wood properties, so were not expected to differ greatly from one another for wood properties.
