Plant Breeders Rights

The strengthening of the intellectual property rights (IPRs) for plant varieties provide incentives for breeding companies to invest more resources in plant breeding. The main objective of this paper was to analyze the effects of strengthening the wheat variety intellectual protection on wheat productivity and the release of new varieties. The strength of IPR systems was measured using an intellectual property (IP) protection index, and plant breeders’ rights (PBRs) granted for wheat varieties. The empirical analyses were based on correlation and multiple regression analyses. The results showed that strengthening IPR systems in South Africa contribute to improving wheat productivity and increasing the number of wheat varieties released. Furthermore, although the robust coefficients of the other IPR variables are positive, they are statistically insignificant for all scenarios. There is a need for more incentives beyond granting PBRs and strengthening of IPR systems to be provided in the whole wheat sector to stimulate increased investments and the release of new varieties.

<p>The present study aimed to evaluate the effect of the wheat varieties newly introduced in Rwanda on the physicochemical characteristics of their whole wheat grains in order to know their potentials for processing. Gihundo wheat grain variety had the highest values for extraction yield (99.20 %), contents of ash (1.47 %) and total dietary fiber (15.97 %), water absorption capacity (89.00 %), dough development time (7.62 min) and brightness (84.67 %). For the same physicochemical characteristics, whole flour from Nyaruka wheat variety showed the lowest values for extraction yield (96.20%), water absorption capacity (80.00 %), dough development time (6.33 min) and brightness (80.33), while whole flour from Reberaho wheat variety exhibited the lowest values for the contents of ash (0.98 %) and total dietary fiber (12.44 %). The protein content ranged between 10.00 % and 10.85 % for whole flours from all wheat varieties. The results showed that whole flour from Gihundo wheat grain variety exhibited high values for most of the physicochemical characteristics determined in comparison to the other three varieties. It is important to select grains or flour from these wheat varieties newly introduced in Rwanda based on the individual cultivar because their derivative products could have a more desired quality.</p>

Plant Breeders Rights

The adoption of the Arusha Protocol for the Protection of New Varieties of Plants (Arusha Protocol) in 2015 created a harmonized regional legal mechanism for the protection of plant breeders’ rights (PBRs) in the African Regional Intellectual Property Organization (ARIPO) member states. Regrettably, the Arusha Protocol, which is to enter into force after the requisite ratifications, reaffirms the often criticized International Convention for the Protection of New Varieties of Plants of 1991 (UPOV 1991) in its extensive limitation of the traditional farmers’ rights to freely save, replant and exchange seeds of protected plant varieties, while liberally conceptualizing PBRs. The stated farmers’ rights are essential for the food security of the developing ARIPO member states, as their agriculture is predominantly characterized by impoverished small-scale farmers who rely on informal seed exchanges. On that basis, this article is premised on the view that the legal regime for plant varieties protection established under the Arusha Protocol is inappropriate for ARIPO members as it fails to balance breeders’ and farmers’ rights in a manner that promotes food security. It proceeds to evaluate the appropriate approach that can suitably balance breeders’ and farmers’ rights for the purposes of promoting food security in Africa.

Variety Protection

Breeders persistently supply farmers with the best varieties in order to exceed consumer demand through plant-breeding processes that are resource-intensive. In order to motivate continuous innovation in variety development, a system needs to provide incentives for plant breeders to develop superior varieties, for example, exclusive ownership to produce and market those varieties. The most common system is the acquisition of intellectual property protection through plant variety protection, also known as the breeder’s right. Most countries have adopted the system established by the International Union for the Protection of New Varieties of Plants (UPOV). To be granted plant variety protection, the variety should prove to be unique by meeting three requirements: distinctness, uniformity, and stability. This review summarizes (1) the plant variety protection via UPOV convention, (2) technical methods for distinctness, uniformity, and stability testing via phenotype, molecular markers, and sequencing as well as their challenges and potentiality, and (3) additional discussions in essentially derived variety, value for cultivation and use testing, and open source seed initiative.

Given their value for both agriculture and biodiversity, seeds are the target of controversial efforts to establish intellectual property rights and variety protections that regulate sale, exchange, and breeding of genetic resources. This article examines seed governance in Turkey, a country in which many farmers continue to rely on “traditional” wheat varieties. It analyzes the tensions and ambiguities in seed governance that arise at the intersection of Turkey's goals of development and diverse priorities imposed by international frameworks. Seed governance is the product of an open-ended process of strategic elaboration among constituencies involved in trade, agriculture, development, and conservation. Although contradictions among international regulations present an array of choices, many countries including Turkey adopt laws that favor commercialization and privatization. This convergence results not simply from imposition of regulation from above, but also from developing countries' adoption of dominant global perspectives on the “modern” seed and agricultural progress.

The aim of the study was to monitor the virulence of Puccinia graminis Pers. f. sp. tritici in the North Caucasus.  The objectives of the study were to collect P. graminis infectious material from sown winter wheat varieties and evaluate the long-term dynamics of the pathogen virulence in the North Caucasus region in 2014-2019. As a result, an analysis of the virulence of the stem rust pathogen population of wheat collected in Krasnodar, Stavropol Territories, and Rostov Region was carried out. 81 mono-empty mushroom isolates were isolated and differentiated.  The genes Sr5, Sr31, Sr38 were characterized by high efficiency.  On the lines with the genes Sr7b, Sr8b, Sr9f, Sr9g, Sr10, Sr11, Sr12, Sr13, Sr14, Sr21, Sr22, Sr23, Sr26, Sr29, Sr32, Sr33, S35, Sr37, SrDp2, SrWLD, a variation in the virulence frequencies of P. graminis was observed.  Significant changes (in the direction of increasing occurrence) in the North Caucasian population 2014-2019  the pathogen was noted in the frequency of clones virulent to wheat lines with resistance genes Sr11, Sr21, Sr22, Sr26, Sr32, Sr33. A decrease in the frequency of clones virulent to Sr8b, Sr9g, Sr10, Sr12, Sr14, Sr35. At approximately the same level, the occurrence of clones virulent to the genes Sr6, Sr7a, Sr8а, Sr9a, Sr9b, Sr9d, Sr9e, Sr13, Sr15, Sr16, Sr17, Sr19, Sr20, Sr24, Sr25, Sr27, Sr30, Sr36, Sr39, Sr40, Sr44, SrGt, SrTmp. Effective genes that have shown their resistance to P. graminis in the seedling phase are proposed for use in breeding in southern Russia to create new varieties of wheat.
