项目摘要

Yard long bean (cowpea) and chili pepper were mainly investigated. In yard long bean or cowpea, more than 300 cultivars, collected from various areas, including South, Southeast and East Asia, were used for the analysis of morphological, ecological and biochemical characteristics. Seed morphology of those local cultivars indicated the close relationship between local cultivars in Philippines and Indonesia and those in Japan. Field survey in Seinan Islands also suggested the same tendency. These facts seem to suggest that yard long bean or cowpea moved through Seinan Islands in old days. The results of seed protein analysis did not show clear tendency on this matter. More detailed analysis is necessary, using DNA finger print technique. Regarding chili pepper, local cultivars of bird pepper (Capsicum frutescens L.) were mainly analyzed. In morphological and ecological characteristics, local cultivars in Seinan Islands were not as diverse as those distributed in Southease Asian countries. This fact shows that Seinan Islands is situated the edge of the dissemination pathway of this crop in Asia. The analyzes on seed protein, VLS appearance when crossed with Capsicum baccatum, and the appearance of blanches without virus syndrome did not indicate clear tendency. More detailed studies are needed on these items.

主要研究了豇豆和辣椒。对采自南亚、东南亚和东亚等地区的300多个品种的豇豆进行了形态、生态和生化特征分析。这些地方品种的种子形态表明菲律宾和印度尼西亚的地方品种与日本的地方品种关系密切。在塞南群岛的实地调查也显示出同样的趋势。这些事实似乎表明，一码长豆或豇豆在古代通过塞南群岛传播。种子蛋白分析结果对这一问题没有明确的倾向。更详细的分析是必要的，使用DNA指纹技术。在辣椒方面，主要分析了鸟椒（Capsicum frutescens L.）的地方品种。在形态和生态特征上，塞南群岛的地方品种不像东南亚国家那样多样化。这一事实表明，塞南群岛位于该作物在亚洲传播途径的边缘。与辣椒杂交后的籽粒蛋白、VLS外观和无病毒综合征的白化外观分析没有明显的趋势。需要对这些项目进行更详细的研究。
