5 (passport analysis out-of stuff from inside the 70s and you may 1980s). A) Potato landraces distribution for the Ecuador. The study parts chose because of it analysis integrated: B) State from Carchi (northern of the nation), C) Province off Chimborazo (main a portion of the nation) and you can D) Province out of Loja (south of the nation).
目次
In that way, just how many farmers had a need to meet the requisite overall regarding fifty farmers per search town are achieved
The sooner potato range objectives regarding the 1970s and eighties produced more than 400 https://datingmentor.org/tips-and-tricks-on-how-to-get-laid-on-tinder/ accessions of Ecuadorian potato landraces. This type of trials included 82 accessions off Carchi, 35 off Chimborazo and you will 41 regarding Loja. not, over the years, accessions was indeed shed and just 91 Ecuadorian potato landraces remained handled ex situ at the time the original collection issues for this research was basically performed during the 2006.
While the carried out in the earlier stuff, we browsed the latest cantons Espejo, Mira, Este Angel, Huaca, Montufar, San Gabriel and Tulcan in the Carchi; Chunchi, Colta, Guamote, Guano, Penipe and you will Riobamba in Chimborazo (the latest canton Alausi try one of them range, yet not about 70s-eighties range), and you will Gonzanama, Loja and Saraguro into the Loja. The brand new collections used the fresh strategy already employed by INIAP or any other gene banking companies ( Castillo and you can Herman, 1995 ). The fresh new farmers have been advised of your intent behind this study and you will it wanted to deliver the material into the loan companies. Because there is actually zero information about anyone producers which were decided to go to on collection objectives regarding seventies and you can eighties, information is gained in any mi-crocenter to possess farmers holding “dated potato landraces”, with the expectation this snowball approach manage submit certain information about the newest holders out-of landraces. The brand new research out-of landraces was not simply for the individuals currently said, but for all of the offered dated landraces. Immediately after meeting a specific landrace, almost every other landrace with the exact same title out of various other character from inside the a similar canton is actually discarded. Landraces was indeed just amassed when the morphological looks are (slightly) unlike new synonym landrace. Every range is a sample of five in order to ten tubers. After every collection journey, the brand new potato samples have been brought to the brand new INIAP-Santa Catalina Fresh Station within the Quito to own propagation and assessment.
To collect factual statements about with the-ranch potato preservation regarding three browse areas, a survey with 32 inquiries try prepared (Appendix step one). 50 (50) producers were selected within the for every single research city. First, the growers one considering germplasm was in fact questioned. Following, this type of growers have been questioned to point most other potato farmers from the area which were already broadening potato landraces or is growing them before. In the picked facilities, the fresh interview were finished with often men or women, based on accessibility.
Which fieldwork is actually carried out out of
Three you to definitely-all the time character group meetings have been planned inside for every browse urban area: one out of Tenta-Loja (), and history one out of Pisicaz-Chimborazo (). Such group meetings had about three objectives: step one. to add growers which have viewpoints about surveys, dos. so you’re able to describe some of the issues that emerged on the interview, step 3. to go back landraces compiled from inside the each investigation urban area on the producers. Most of the producers involved in the collection and you may survey techniques was basically anticipate.
All of the information throughout the surveys is actually canned when you look at the Do well databases and you will shipped to SPSS fifteen.0 getting study (SPSS Inc., USA). Detailed statistics and bi-variate correlations (Pearson, two tailed) were achieved.
The fresh new snowball approach regularly pick producers saving potato landraces was energetic. The fresh new farmers when you look at the for each place talked about other farmers with certain landraces. Immediately after researching most of the possible producers regarding areas that have landraces, but into the Chimborazo where so much more growers got landraces inside their sphere, different landraces was in fact tracked having range. Inside the first stop by at Carchi, 14 accessions away from potato landraces was basically gathered on the Montufar canton. The second travels afterwards that seasons extra another 38 landraces. Having Chimborazo, INIAP-CIP held a portfolio objective during the early 2006 to help you a few cantons: Colta and you can Guamote. At the time, 46 landraces have been collected. A complementary range done in 2008 various other cantons (Guano, Penipe, Rio-bamba, Alausi and you may Chunchi) led to sixteen the newest landraces. Within the Loja, during , sixty potato landraces had been accumulated. All in all, 174 landrace accessions was basically collected out of 17, twenty-eight and you will 31 growers for the Carchi, Chimborazo and you can Loja, correspondingly. Producers growing potato landraces have been scarcer within the Carchi and you will distribute in the Loja (and therefore much harder to locate), while in Chimborazo most of the farmers (for instance the native organizations) left old landraces within sphere.
