Insect Resistance and Horticultural Trait Genetic Values of Potato Families
Velci Queiróz de Souza,Arione da Silva Pereira,Giovani Olegário da Silva,Fernando Irajá Félix de Carvalho,Antônio Costa de Oliveira 한국작물학회 2008 Journal of crop science and biotechnology Vol.11 No.1
This work aimed to evaluate 11 potato families for insect resistance horticultural traits. The families were derived from crosses between introduced insect resistant and adapted genotypes. A randomized complete block design, with three replications was used. The plot consisted of 25 genotypes of a family, summing up to 75 genotypes tested per family. Two susceptible cultivars were included in the experiment as controls. The genotypes were evaluated for insect resistance, tuber yield traits, tuber appearance, and tuber skin smoothness. The genetic value for the intensity of insect attack in the leaves and in the tubers was lower (higher resistance) in the 11 families than in the controls. For yield traits, there was no predominant effect among the families regarding the origin of the resistant donor species (Solanum berthaultii and/or S. chacoense). However, there was a large contribution of the C-1485-16- 87 recurrent parent in crosses with resistant genotypes for tuber yield and tuber number. In relation to tuber appearance, only the family derived form the C-1485-16-87/ND140 (S. berthaultii) cross did not differ from the controls. For tuber skin smoothness, the genetic values of the families did not significantly from each other or from the controls.

A randomized complete block design, with three replications was used. The plot consisted of 25 genotypes of a family, summing up to 75 genotypes tested per family. Two susceptible cultivars were included in the experiment as checks. The genotypes were evaluated for insect resistance, tuber yield traits, tuber appearance and tuber skin smoothness. The genetic value for the intensity of insect attack in the leaves and in the tubers was lower(higher resistance) in the 11 families than in the checks. For yield traits, there was no predominant effect among the families regarding the origin of the resistant donor species(Solanum berthaultii and/or S. chacoense).

In relation to tuber appearance, only the family derived form the C-1485-16-87/ ND140(S. berthaultii) cross did not differ from the checks. had genetic value tuber skin smoothness, it was identified that families derived from S. berthaultii resistant parents showed higher genetic values than the check cultivars. For tuber skin smoothness, the genetic values of the families neither differed significantly from each other nor from the checks.
Smart Specialisation Strategy and the Role of Strong Clusters: As a Development Leverage in Asia
Anastasopoulos, Despina,Brochler, Raimund,Kalentzis, Arion Louis World Technopolis Association 2017 World Technopolis Review Vol.6 No.2
In this increasingly globalised and rapidly-changing world, the various challenges that can arise are also increasingly globalised and complex. These may range from economic, environmental, societal or even demographic challenges. Solutions should therefore be applicable world-wide, but they need to be properly adapted to the specifications and needs at the regional and country level. This implies that past models of centralised innovation can be progressively substituted by new approaches based on openness and strategic collaboration between the various players involved. There are various models of openness and collaboration in research, development and innovation creating scientific networks at different levels. This paper is designed in a way to present the concept of smart specialisation and clusters and how they are linked and contribute to the support of Smart Specialisation Strategy in the Asian countries. The following paragraphs describe how smart specialisation is applied and the importance of clusters in developing a S3 strategy. In addition, the status of cluster policies in Asia as well as the steps towards S3 are also presented. The status of cluster policies and their steps towards S3 policies in Asia are described. The approach of China to adopt S3 in their R&I policy is also presented. The scope of this paper, is to demonstrate the policy framework of cluster and S3 policies in the region of Asia and how they are applied. China has been further analysed as a case, since they are more active in applying such policies.
