outcross

Overall, mortality of selfed progeny exceeded that of outcrossed progeny in 63 of 71 families (outcrosses exceeded selfs in 8 families: 1 in D2, 1 in T2, 4 in T4, 2 in T26), a significant difference between self and outcross treatments.

Data pooled across isolations were analyzed with the SAS model, outcross = isolation replicate(isolation) line isolation x line.

However, if self progeny are less than half as fit as outcross progeny due to inbreeding depression, the transmission bias is nullified and the spread of alleles that increase the selfing rate is prevented (e.g., Maynard Smith 1971; Charlesworth and Charlesworth 1979, 1987, 1990; Lloyd 1979; Lande and Schemske 1985).

Here we report on late-acting inbreeding depression and selection in progenies from mixed mating after competition has developed between inbred and outcross progenies of a long-lived forest-tree angiosperm, Eucalyptus regnans Muell.

The Outcross 9060 continues to be a crowd favorite as customers learn more about the various attachments and versatility this machine offers to help address some of their biggest challenges.

Seed production from hand outcrosses and natural pollination.--To estimate the maximum number of seeds that could be produced per flower under outcross pollination conditions, six unopened flowers on each of six plants per population were emasculated while in bud.

"The fastest way to get genetic diversity is to outcross to a breed that looks similar but is genetically distinct.

"There are chart-topping PLI sires, top type sires and outcross sires; no matter what your preference in breeding, this sale has it covered."

It could be that this settling behavior and patchy distribution, without resulting in intra-specific competition, allow for ample opportunities to outcross, as well as minimize the chances of taking up own-self sperm.
