Protocol for assessing bacterial wilt resistance in greenhouse and field conditions. International cooperators’ guide
No full textThis protocol is an updated version of “Assessing potato clone field resistance to bacterial wilt” issued in The International Cooperators’ Guide (CIP 2007). The first edition of the protocol presented a standard procedure for field assessment of resistance to bacterial wilt for documenting levels of resistance of advanced potato germplasm. This second edition has included a standardized procedure for greenhouse screening of potato seedlings for bacterial wilt resistance useful for perform genetic studies, parental selection or identification of new sources of resistance in accessions of wild species propagated or maintained as true see

Evaluation of Advanced Potato Clones for Drought Tolerance in Arid Zone in Rajasthan, India
No full textPotato is a cool season crop and
requires optimum soil moisture throughout
its growing period and its productivity is
hampered to a great extent in absence of these
favorable conditions (Cabello et al., 2013).
Exploitation of the gene pool is required for
identifying and evaluating clones suitable
for drought tolerance. Genotype-specific
differences have been reported in potato
for tuber productivity and quality under
combined environment of drought and heat
stresses (Ahn et al., 2004). Efforts are under
way to breed and screen potato clones for
adaptation to adverse agro-ecologies in a
collaborative endeavor of the Central Potato
Research Institute and the International Potato
Center (CIP).
A site was selected near Jodhpur, Rajasthan
(26° 17’12’’ N, 73° 01’48’’ E, 235 meters above
sea level) to evaluate the advanced CIPbred
clones under moderate water stress
conditions during 2012-13 crop season. This
was an attempt to introduce the potato crop
to the hot arid zone of Western India, where
water is scarce for field crops, livestock and
human beings. Ultimately, among CIP clones 397006.18 was found promising based upon its overall yield performance, drought tolerance and acceptability of texture and taste
Selección y evaluación de nuevos clones de papas precoces con tolerancia a calor y resistencia a PVY
No full textpp.113-114. Sección GM6.Desde sus inicios el Centro Internacional de la Papa (CIP) usando un vasto pool de genes contenido tanto en especies cultivadas como en silvestres ha generado una población altamente heterogénea y heretozigótica con resistencia a los virus mas importantes (PVY, PVX y PLRV) y adaptación a los trópicos y climas calidos (Mendoza y Estrada, 1977), a esta población se le denomina LTVR (de sus siglas en ingles lowland tropic virus resistant) que combina tolerancia a calor, precocidad y resistencia a virus (Bonierbale, et al 2009). En el mejoramiento de esta población se utiliza un esquema de selección fenotípica recurrente con selección de progenitores con prueba de progenie. El objetivo del mejoramiento del CIP esta enfocado en un mejoramiento de germoplasma con resistencia a las principales enfermedades (tizón tardío y virosis) y tolerancia a factores abióticos (calor y sequía). Este germoplasma es distribuido a los países en desarrollo y más pobres del mundo que mayormente se encuentra en la región tropical. Dada la necesidad de contar con materiales genéticos más precoces y tolerantes al calor que las variedades actuales, se ha generado un nuevo grupo de materiales con estas características
Status of the draft potato ontology.
No full textThe potato ontology is being developed as part of the crop ontology (CO) effort amongst CGIAR centers. The CO serves primarily to harmonize phenotypic and genotypic data for semantic compatibility across diverse, distributed data types; and ontology in general, facilitates the use of terms by both humans and algorithms. Other potential uses include knowledge transfer across species and predictions. The case of potato presents several opportunities to test and evaluate the different uses of ontologies: a) potato has more than 100 tuber-bearing wild relatives, b) the potato genome and that of its sister species, tomato, have recently been sequenced, and c) conserved orthologous set (COS) gene sequences markers have been mapped in the physical and genetic map of potato and tomato. On the other hand potential constraints are: a) potato is outbreeding and has a high level of diversity at genotype and phenotype level; and b) predictivity of transferring knowledge between species has been weak in the past. In this talk we will present main advances and pendings to date around the use of the potato ontology. These include: a) development of a first potato ontology based on the former FAO/IPGRI/CIP morphological descriptor list and trait dictionaries from standard evaluation trial protocols; b) the P4 initiative open to collaborators for phenotyping and gene discovery from the DMDD progeny of the sequenced genome, DM ,and c) a federated web database using biomart for integrating genome scale and field trial data. Current efforts include the addition and standardization of new phenotypes, as well as improving the ontology draft in terms of coverage of data types and cross linking to the general plant as well as to the Solanaceae Phenotype Ontology
