Our data suggest that numerous genes directly or indirectly involved in flowering regulation play pleiotropic roles in adaptation to environmental stresses, and thus represent important genetic factors to be considered for adaptive breeding.
Though healthy, Marius was considered unsuitable for breeding because his genes were too common, so it was decided by the authorities to put him down.
Like his namesake in Copenhagen, the giraffe is considered unsuitable for breeding, and the zoo said there was a high risk that Marius would have to be put down as it would be difficult to find him a new home.
The death of Marius, an 18-month-old giraffe considered useless for breeding because his genes were too common, was followed by his dissection in front of a large crowd, including fascinated-looking children, prompting outrage and protests around the world.
In a nucleus breeding population, such individuals cannot be considered for use as breeding stock and effectively end up as culls.
Furthermore, several important first cycle recombinant lines derived from PHG39 have been considered for commercial maize breeding [ 10].
First, from the second generation, both females and males older than one year old were considered as mature for breeding and a male could be mated during at most two breeding years.
However, if the cause of death of a BMD shall be considered for the purpose of breeding selection, for the evaluation of genetic tests and breeding value estimations, a definitive diagnosis is essential.
These aspects should be considered while breeding for robust forms of resistance to blast disease.
Whereas several QTLs for drought stress tolerance and resistance to rust and foliar diseases have been reported in peanut [ 24- 26, 28, 31], QTL analyses focused on morphological and physiological traits considered important for breeding have not been conducted.
