Using Wild Olives in Breeding Programs: Implications on Oil Quality Composition

Using Wild Olives in Breeding Programs: Implications on Oil Quality Composition

A wide genetic diversity has been reported for wild olives, which could be particularly interesting for the introgression of some agronomic traits and resistance to biotic and abiotic stresses in breeding programs. However, the introgression of some beneficial wild traits may be paralleled by negative effects on some other important agronomic and quality traits. From the quality point of view, ...

Fruit size in wild olives: implications for avian seed dispersal

Frugivorous birds in the Mediterranean basin may disperse seeds using two different feeding behaviours: swallowing the fruit whole or pecking pieces of pulp. Swallowing is the common behaviour of frugivorous seed dispersers in the Mediterranean basin (Herrera 1984a) and most of the fleshy-fruited plants in the region rely on this bird feeding behaviour to disperse their seeds (Herrera 1984b, 19...

Using markers in gene introgression breeding programs.

We investigate the use of markers to hasten the recovery of the recipient genome during an introgression breeding program. The effects of time and intensity of selection, population size, number and position of selected markers are studied for chromosomes either carrying or not carrying the introgressed gene. We show that marker assisted selection may lead to a gain in time of about two generat...

Application of myostatin in sheep breeding programs: A review

Myostatin or growth and differentiation factor 8 (GDF8), has been known as the factor causing double muscling phenotypes in which a series of mutations make the myostatin protein inactive, hence disabling it to regulate the deposition of muscle fibre. This phenotype happens with high frequency in a breed of sheep known as the Texel. Quantitative trait loci (QTL) studies show that a portion of t...
