Do New Breeding Techniques in Ornamentals and Fruits Lead to Essentially Derived Varieties?

Essentially Derived Varieties in Ornamentals

The concept of Essentially derived varieties (EDVs) was introduced in the UPOV 1991 act to protect the interests of the breeder of the initial variety. When a variety is considered as an EDV, authorisation for commercial exploitation is needed from the breeder of the initial variety. There is considerable debate going on about which approaches to use for determining essential derivation and als...

Do essentially conditional information inequalities

We show that two essentially conditional linear information inequalities (including the Zhang–Yeung’97 conditional inequality) do not hold for asymptotically entropic points. This result raises the question of the “physical” meaning of these inequalities and the validity of their use in practice-oriented applications.

Rootstock Breeding for Stone Fruits

Over the last 20 years stone fruit rootstock development has begun shifting from seedling to clonal types, many of interspecific origin. Publicly funded breeding programs have produced most of these rootstocks due to the time, cost, and risk associated with their development; however, private industry is emerging as a significant contributor of many of the newer rootstocks. Particularly notewor...
