The reported narrow genetic base of cultivated potato (Solanum tuberosum) can be expanded by the introgression many related species with large diversity. analysis structure a population is important to broaden breeding programs identification different pools. A panel composed 231 diverse genotypes was characterized using single nucleotide polymorphism (SNP) markers Illumina Infinium Potato SNP Array V2 identify and assess diversity discriminant principal components (DAPC) pedigree analysis....
Ten institutions in nine countries joined together to test the stability of resistance 14 potato genotypes oomycete pathogen Phytophthora infestans three separate trials. Seven were tested one trial involving seven locations, and all two subsequent trials, each eight locations. Stability was with nonparametric tests an additive main effects multiplicative interaction (AMMI) model. Overall, P. robust; resistant consistently locations The analysis indicated that specific basically stable...
Abstract Potatoes is often considered a drought‐sensitive crop and its sustainable production threatened due to frequent drought episodes. Drought tolerance complex trait of increasing importance in potatoes therefore yield threatened. The differential response several physiological agronomical traits was evaluated diverse panel under contrasting water regimes identify quantitative loci (QTL) associated with using genome‐wide association analysis 4859 high‐quality SNP markers. Phenotypic...
In potato, dry matter (DM) production and partitioning between plant organs N accumulation are affected by application; however, since cultivars differ in these processes, fertilization must be adjusted to each cultivar. This paper studies the response of potato differing maturity south-east Buenos Aires Province (37°45′S, 58°18′W) two growing seasons. Treatments combined four doses (0–180 kg ha−1) cultivars: Jaerla (early), Spunta (mid-early), Mailén INTA (medium late) Huinkul MAG (late)....
With 3 figures and 2 tables Abstract Late blight is the main disease of potatoes around world. Because difficulties in applying effective control methods, introduction resistant cultivars represents a safe strategy. The potato species Solanum tarijense an attractive resistance source as its adaptation to long days promissory, producing tubers good size aspect. Deposition structural compounds like lignin callose were described non‐specific mechanism. In this work, we measured...
Abstract Potato leaves infected with Phytophthora infestans produced a serine protease inhibitor ( PLPKI ) specificity for microbial proteases. Sequencing of the first twenty residues at NH 2 ‐terminus mature polypeptide demonstrated that is novel member potato I family. inhibited activity extracellular proteases by two pathogens potato, P. and Rhizoctonia solani , but was inactive against secreted into culture media binucleate N2, non‐pathogenic fungus potato. Western blot analysis showed...
Diversity in crops is fundamental for plant breeding efforts. An accurate assessment of genetic diversity, using molecular markers, such as single nucleotide polymorphism (SNP), must be able to reveal the structure population under study. A characterization easy measurable phenotypic traits could a preliminary and low-cost approach elucidate population. potato 183 genotypes was evaluated 4859 high-quality SNPs 19 commonly recorded programs. Bayesian approach, Minimum Spanning Tree (MST)...
En 1984 se entrecruzaron 25 clones y cultivares de papa con el objetivo desarrollar un método para tamizado por alto peso específico (PE) en generaciones tempranas. Se midió PE tubérculos producidos plántulas trasplantadas macetas a campo. Los seleccionados 1986 originar segundo ciclo selección. La variabilidad registrada entre familias medios hermanos los dos ciclos fue altamente significativa (p<0.01). Las heredabilidades sentido estricto primer fueron 0.51 mayor 0.9 respectivamente....
ABSTRACT The nature of spatial and temporal dynamics Tomato spotted wilt virus (TSWV) its vector in a potato crop cv. Innovator without insecticide application is analysed. Seed tuber was analysed for the presence TSWV as source initial inoculum. plants with symptoms evaluated by visual observation DAS‐ELISA analysis to confirm infection. Thrips species were collected from leaves inflorescences identified under stereomicroscope. distribution symptomatic thrips recorded five times at 14 days...
Se estudió la multiplicación de plántulas papa empleando técnicas micropropagación en un sistema semejante a los utilizados hidroponía.Se utilizaron segmentos uninodales obtenidas por micropropagación, que se cultivaron autotróficamente, sin agregar sacarosa ni reguladores del crecimiento; para ello fue necesario evaluar contenedores descartables, substratos y soluciones nutritivas. Además, buscó método permitiera propagación las lo cual evaluaron microesquejes distinta ubicación planta...
