5 (passport analysis out of collections for the 1970s and you can eighties). A) Potato landraces shipping inside Ecuador. The study elements chosen for this investigation provided: B) Province of Carchi (north of the country), C) State out-of Chimborazo (main a portion of the nation) and you can D) Province from Loja (southern area of the nation).
Like that, what amount of producers necessary to meet up with the called for full from 50 growers for every single browse city try hit
The earlier potato collection objectives regarding 70s and you can mid-eighties yielded more than 400 accessions away from Ecuadorian potato landraces. These types of samples incorporated 82 accessions away from Carchi, 35 out-of Chimborazo and you will 41 off Loja. But not, over the years, accessions were forgotten and only 91 Ecuadorian potato landraces were still was able ex situ during the time the first range affairs getting this study were did in 2006.
Due to the fact carried out in the earlier choices, i looked the new cantons Espejo, Mira, El Angel, Huaca, Montufar, San Gabriel and Tulcan in the Carchi; Chunchi, Colta, Guamote, Guano, Penipe and you will Riobamba from inside the Chimborazo (the fresh canton Alausi is actually one of them range, yet not regarding the 1970s-1980s collection), and you may Gonzanama, Loja and you can Saraguro in the Loja. The fresh collections implemented new methods already used by INIAP and other gene banks ( Castillo and you may Herman, 1995 ). The new farmers was basically told of your own aim of this study and you will it provided to provide the content with the loan companies. Since there is actually no information on anyone growers which were decided to go to regarding range missions from the 1970s and you will eighties, suggestions are attained in just about any mi-crocenter to own farmers holding “old potato landraces”, on the expectation this snowball method carry out deliver specific information in regards to the most recent holders out-of landraces. The latest search away from landraces wasn’t limited to those people already advertised, but also for every available old landraces. Shortly after meeting a specific landrace, virtually any landrace with the exact same term out-of other farmer inside the an identical canton is thrown away. Landraces was basically only gathered if the morphological physical appearance was (slightly) unlike the fresh new synonym landrace. The collection is actually a sample of 5 to help you ten tubers. After each and every collection journey, the latest potato examples was delivered to the latest INIAP-Santa Catalina Fresh Station within the Quito to own propagation and you can investigations.
To gather facts about on the-ranch potato conservation regarding the three research components, a questionnaire which have 32 concerns was wishing (Appendix step one). 50 (50) producers was chosen during the for each browse area. 1st, all of the producers that given germplasm have been questioned. Following, these producers had been requested to indicate almost every other potato farmers on the town that were currently expanding potato landraces or was actually broadening her or him in the past. During the picked facilities, the brand new interview was through with often women or men, based on availability.
This fieldwork was achieved out of
About three you to-all day long character group meetings was in fact organized for the for each and every lookup town: one in Tenta-Loja (), and history one out of Pisicaz-Chimborazo (). These conferences got around three objectives: step one. to include farmers having views throughout the studies, 2. in order to describe a few of the issues that emerged regarding interview, 3. to return landraces collected in for each and every investigation area to the growers. All of the farmers mixed up in collection and survey processes had been acceptance.
Most of the recommendations on the surveys is actually canned in the Do well databases and exported to SPSS fifteen.0 to possess data dating site for Interracial people (SPSS Inc., USA). Detailed statistics and bi-variate correlations (Pearson, two tailed) were accomplished.
The fresh new snowball techniques used to come across producers preserving potato landraces was productive. This new farmers within the for each location mentioned almost every other growers having particular landraces. Once learning all of the prospective growers regarding components which have landraces, but when you look at the Chimborazo where a lot more growers got landraces within industries, additional landraces was indeed tracked having range. Inside the first trip to Carchi, fourteen accessions regarding potato landraces were accumulated about Montufar canton. An additional trip later one 12 months additional various other 38 landraces. To have Chimborazo, INIAP-CIP presented a portfolio goal during the early 2006 to a couple of cantons: Colta and you can Guamote. At that time, 46 landraces was collected. A subservient collection done in 2008 various other cantons (Guano, Penipe, Rio-bamba, Alausi and Chunchi) contributed to 16 the landraces. During the Loja, while in the , sixty potato landraces was indeed amassed. A maximum of 174 landrace accessions have been gathered away from 17, twenty-eight and 29 producers from inside the Carchi, Chimborazo and you can Loja, correspondingly. Producers broadening potato landraces was scarcer within the Carchi and you can distribute in the Loja (and therefore more difficult locate), during Chimborazo every growers (including the native organizations) remaining old landraces in their fields.
