【摘要】：基于河南和山东农户调研数据,采用选择实验方法,应用随机参数模型与潜在类别模型分析农户对夏玉米品种的生育期、与干旱相关的产量特征、籽粒品质及穗位整齐度性状属性的偏好与支付意愿。研究表明,农户对玉米品种性状偏好具有异质性,根据这种异质性可以将农户分为穗齐偏好农户和产量稳定偏好农户,但追求产量目标的农户少于追求轻简目标的农户;农户对玉米品种的穗位整齐度的支付意愿最高,其次为玉米的产量特征和生育期,对玉米籽粒的品质属性支付意愿最低。因此,培育耐旱稳产型、适宜机械化操作的穗齐型且生育期较短的"轻简型"玉米品种是中国玉米育种的主要方向。
[Abstract]:Based on the survey data of farmers in Henan and Shandong province, the random parameter model and potential category model were used to analyze the growth period of summer maize varieties and the yield characteristics related to drought. Preference and willingness to pay for grain quality and ear uniformity. The results showed that farmers' preference for maize variety traits was heterogeneity. According to this heterogeneity, farmers can be divided into predilection farmers and yield stability preference farmers, but the farmers who pursue the yield goal are less than those who pursue the light simple goal. Farmers had the highest willingness to pay for ear uniformity of maize varieties, followed by yield characteristics and growth period of maize, and the lowest willingness to pay for the quality attributes of maize grains. Therefore, the cultivation of drought-tolerant and stable yield type. The main direction of maize breeding in China is the "light simplified" maize varieties, which are suitable for mechanized operation and have a short growth period.

【正文快照】： 一、引言在提高玉米单产水平的各种技术手段中,品种更新一直倍受关注。然而,近年来中国玉米品种不但更新速度慢,且种业同质化现象严重[1]。与此同时,跨国种业巨头纷纷进入中国抢占市场,由美国先锋公司选育的先玉335作为国外品种占据中国市场已经给中国玉米种业敲响了警钟。随
