5 (passport research out of selections from inside the 1970s and you will 1980s). A) Potato landraces distribution during the Ecuador. The research areas picked for it studies provided: B) Province off Carchi (north of the country), C) State out-of Chimborazo (main the main nation) and D) Province from Loja (southern of the nation).
In that way, just how many producers necessary to meet with the needed total out-of 50 growers for every browse area are attained
The earlier potato collection missions regarding the 70s and you can eighties produced more eight hundred accessions out of Ecuadorian potato landraces. These types of trials incorporated 82 accessions regarding Carchi, thirty-five from Chimborazo and you can 41 out-of Loja. not, usually, accessions was destroyed and just 91 Ecuadorian potato landraces remained handled old boyfriend situ at the time the first collection affairs for this research was performed in 2006.
As the carried out in the earlier choices, i browsed this new cantons Espejo, Mira, Este Angel, Huaca, Montufar, San Gabriel and you may Tulcan in Carchi; Chunchi, Colta, Guamote, Guano, Penipe and you will Riobamba for the Chimborazo (this new canton Alausi was one of them range, however throughout the 1970s-1980s range), and you may Gonzanama, Loja and Saraguro when you look at the Loja. This new collections then followed the strategy currently utilized by INIAP or any other gene banking companies ( Castillo and you can Herman, 1995 ). New producers were informed of one’s purpose of this research and you will they offered to provide the material into the loan companies. As there was zero information about the person farmers that were visited throughout the range objectives regarding the 70s and you may mid-eighties, recommendations was achieved in virtually any mi-crocenter to own farmers carrying “old potato landraces”, on the presumption that this snowball techniques perform submit some information concerning newest people regarding landraces. The latest lookup off landraces wasn’t restricted to those people already advertised, but for most of the readily available dated landraces. After collecting a certain landrace, any other landrace with similar name out-of several other character in the an identical canton try discarded. Landraces was only compiled in the event that morphological looks is actually (slightly) distinct from the brand new word landrace. The collection is actually an example of 5 to help you 10 tubers. After each and every range travel, the latest potato samples was in fact taken to the latest INIAP-Santa Catalina Fresh Channel during the Quito having propagation and analysis.
To gather details about to the-farm potato preservation in the three research areas, a survey which have thirty-two questions is prepared (Appendix step one). 50 (50) producers was picked when you look at the per research urban area. First, all farmers you to given germplasm was questioned. After that, such growers was indeed questioned to indicate almost every other potato producers from the urban area that were currently expanding potato landraces or was broadening them prior to now. In the picked facilities, the fresh new interview were carried out with possibly men or women, centered on accessibility.
That it fieldwork are achieved of
Three one to-from day to night farmer meetings was arranged when you look at the for each search town: one out of Tenta-Loja (), in addition to history one out of Pisicaz-Chimborazo (). Such group meetings had about three expectations: step 1. to provide producers which have viewpoints get it on Promo-codes about surveys, dos. so you can explain a few of the issues that emerged on the interviews, 3. to go back landraces compiled in for each and every studies city on producers. The farmers involved in the range and you will survey processes was basically greeting.
The suggestions about studies try canned within the Prosper database and exported in order to SPSS 15.0 for studies (SPSS Inc., USA). Descriptive statistics and you may bi-variate correlations (Pearson, two tailed) was in fact carried out.
The brand new snowball techniques used to find growers conserving potato landraces was energetic. The producers inside the for every single venue mentioned other producers having certain landraces. Immediately after checking every prospective farmers throughout the components which have landraces, except inside the Chimborazo where way more growers got landraces within sphere, additional landraces have been tracked getting range. In the first visit to Carchi, 14 accessions of potato landraces was in fact collected from the Montufar canton. Another journey later that seasons extra another 38 landraces. To have Chimborazo, INIAP-CIP used a profile mission during the early 2006 to help you two cantons: Colta and you may Guamote. At the time, 46 landraces were gathered. A complementary range done in 2008 various other cantons (Guano, Penipe, Rio-bamba, Alausi and you can Chunchi) triggered 16 the fresh landraces. Within the Loja, throughout the , sixty potato landraces have been amassed. A total of 174 landrace accessions have been collected out-of 17, twenty eight and 31 farmers from inside the Carchi, Chimborazo and you will Loja, respectively. Growers broadening potato landraces was basically scarcer inside Carchi and you can distribute for the Loja (and therefore much harder to get), during Chimborazo all of the growers (like the native teams) kept dated landraces within their fields.
