Abstract:

?Variety improvement and new variety adoption play dominant roles in enhancing crop productivity. However, in practice, successful adoption of improved varieties is influenced by multiple factors. This study aimed to investigate farmers¡¯ perception of soybean variety traits and identify factors determining farmers¡¯ variety choices in the three main soybean production regions of China, namely the Northern Spring Soybean Region (NSSR), the Huang-Huai-Hai Rivers Valley Summer Soybean Region (HHHR), and the Southern Multiple.Cropping Soybean Region (SMSR).During 2008-2010, farmers from 22 provinces covering the three main soybean production regions were surveyed by National Soybean Industry R & D System to obtain data about their socioeconomic characteristics and perceptions of variety traits.A binary logit model was applied to identify the factors influencing farmers¡¯ variety choices. The results indicated that high adoption rates of improved varieties of 99.45% in NSSR and 93.40% in HHHR, whereas that in SMSR was 37.55%. In NSSR and HHHR, improved varieties outperformed landraces with respect to all the surveyed traits, particularly high yield, yield stability, lodging resistance, and disease resistance.In SMSR, in contrast, the landraces were superior to improved varieties in yield stability, disease resistance, stress tolerance, processing quality, maturity group, and plant height. Empirical results showed that in NSSR farming experience and off-farm labor strongly influenced variety adoption.With the exception of household socioeconomic factors and the aim of high yield, early maturity in HHHR and lodging resistance in SMSR were the main factors influencing farmers¡¯ variety choices. This study will assist the development of region-specific breeding and extension strategies and further advance of soybean production in Chinaª±
