Dataset for: Participatory Varietal Selection of 11 late blight resistant clones (B1C5) in the localities of Alacoto, Chuquitambo and Macullida in La Libertad, Peru

The Mother and Baby (M&B) trial methodology was adapted by CIP for Participatory Variety Selection (PVS) through decentralized evaluation networks and multi-year evaluations in potato growing areas in the Andean region. The M&B trial design encourages active participation of farmers through the application of treatments through systematic evaluations and selections of treatments in their own plots called "Baby trials" (i.e. farmer managed trials) and in fields with an experimental design called "Mother trials" (i.e. researcher managed trials). Objective: Analyze characteristics, attributes and preferences that men and women have when selecting a new potato variety at the phase of flowering and harvesting. A M&B trial was performed to evaluate 11 clones of the population B1C5 with late blight resistance at the localities of Alacoto, Chuquitambo and Macullida, in the provinces of Pataz and Sanchez Carrion, in La Libertad department, Peru. The trial design was a Randomized Complete Block Design (RCBD) with 3 replicates for Mother trials and 3 replicates for Baby trials during 2012-2013. In this experiment characteristics of plant (size, type of foliage), yield, quality, and pest and disease resistance during flowering and harvesting were evaluated. The number of participants at flowering phase was 20 (men=14 and women=6), 12 (men=5, women = 5), 9 (men=4, women = 5); and the number of participants at harvesting phase was 17 (men=12 and women=5), 12 (men=5, women = 5) and 9 (men=4, women = 5) in Alacoto, Chuquitambo and Macullida respectively. Additionally, an organoleptic evaluation was assessed at harvesting to evaluate appearance, taste and texture. The number of panelists was 10 (men=5, women=5) in Alacoto, Chuquitambo respectively and 10 (men=4, women=6) in Macullida for the organoleptic evaluation.

母子（Mother and Baby, M&B）试验方法由CIP针对参与式品种选育（Participatory Variety Selection, PVS）进行适配改造，依托安第斯地区马铃薯种植区的分散式评估网络与多年度评估体系开展工作。M&B试验设计通过系统性处理评估与筛选流程，鼓励农户积极参与：农户可在自有田块实施“Baby试验”（即农户自主管理试验），并在采用标准化试验设计的田块开展“Mother试验”（即研究人员管理试验）。
研究目标：剖析男女农户在马铃薯开花与收获阶段选育新品种时的性状特征、属性偏好与选择倾向。
本研究开展M&B试验，针对秘鲁拉利伯塔德省帕塔兹（Pataz）与桑切斯·卡里翁（Sanchez Carrion）省内的阿拉科托（Alacoto）、丘基坦博（Chuquitambo）和马库利达（Macullida）三个试点，对携带晚疫病（late blight）抗性的B1C5群体的11个无性系进行评价。2012-2013年间，本试验采用随机完全区组设计（Randomized Complete Block Design, RCBD），其中Mother试验与Baby试验均设置3次重复。试验评估了马铃薯在开花与收获期的植株性状（株高、叶型）、产量、品质及病虫害抗性。
阿拉科托、丘基坦博与马库利达三个试点的开花期参与农户分别为20人（男性14人、女性6人）、12人（男性5人、女性5人）与9人（男性4人、女性5人）；收获期参与农户分别为17人（男性12人、女性5人）、12人（男性5人、女性5人）与9人（男性4人、女性5人）。此外，本试验在收获期开展感官评价（organoleptic evaluation），以评估马铃薯的外观、风味与质地。感官评价的参与评审人员分别为：阿拉科托与丘基坦博试点各10人（男性5人、女性5人），马库利达试点10人（男性4人、女性6人）。
