Replication data for: Adoption and diffusion of potato varieties in Peru

For more than 40 years CIP has worked with the potato breeding program of the National Institute of Agriculture Innovation (INIA) in Peru to develop new genetic material. More than 34 improved varieties have been released in the country under this collaborative framework. Canchan (released in 1990) and Amarilis (1993) are amongst the most popular. Recently released varieties such as Unica (1998) and Serranita (2006) seem to be increasing their adoption rates. Besides meeting market needs, these varieties have higher yields and reduce production costs, increasing farmers’ income and reducing the environmental footprint through lower pesticide use. Estimates of adoption of these varieties have been obtained in the past from expert opinions, or are only partial approximations based on local level studies. Lack of a nationally representative sample has constrained the validity of these estimations and the ability of drawing rigorous conclusions about farmers’ drivers of adoption. These estimates and conclusions are a crucial feedback to adjust breeding strategies while developing new varieties. This database collected during the 2013 growing season were conducted from a nationally representative sample of 1098 potato farmers in 120 communities. The objectives of these database were to quantify adoption and diffusion of improved potato varieties in the most representative production regions of Peru; and to identify adoption determinants of improved potato varieties in Peru and estimate their impacts.

40多年来，国际马铃薯中心（CIP）与秘鲁国家农业创新研究所（INIA）的马铃薯育种项目合作开发新的遗传材料。在此合作框架下，该国已推出34多个改良品种，其中Canchan（1990年推出）和Amarilis（1993年推出）最为普及。近年推出的品种如Unica（1998）和Serranita（2006）的采用率（adoption rate）似乎正在上升。除满足市场需求外，这些品种产量更高、生产成本更低，既能增加农民收入，又能通过减少农药使用降低环境足迹。过去对这些品种采用情况的估计多基于专家意见或局部研究，缺乏全国代表性样本限制了估计结果的有效性，也制约了得出农民采用驱动因素严谨结论的能力。本数据库于2013年生长季收集，样本来自秘鲁120个社区的1098名马铃薯种植户，具有全国代表性；其目标是量化改良马铃薯品种的采用与扩散情况，并识别秘鲁改良马铃薯品种的采用驱动因素及评估其影响。
