    摘要:

    2017-2022年,福建省在第三次全国农作物种质资源普查与收集行动中,共收集作物地方品种和野生近缘植物种质资源6235份,蔬菜、粮食、果树、经济作物、牧草绿肥分别占33.57%、25.91%、24.35%、14.59%、1.57%;所有资源隶属于83科,229 属,313种,其中豆科种质资源份数最多,占总数的16.04%。不同地区和海拔是影响收集农作物种质资源种类和数量的重要因素。全省9个地级市中,三明市收集种质资源数量最多,占20.65%。全省收集农作物种质资源数量随着海拔升高而下降,不同海拔收集数量随着市辖县(市、区)、乡(镇)、村(街道)的数量减少呈现减少趋势。沿海地区如漳州、福州、宁德、泉州、莆田、厦门等6个地级市,海拔0~200 m是种质资源Shannon-Wiener多样性指数和Brillouin丰富度指数最高的海拔区间;闽西北山区,如龙岩、三明、南平等3个地级市,海拔200~400 m、400~600 m、600~800 m种质资源的Shannon-Wiener多样性指数和Brillouin丰富度指数较高。不同地级市、不同海拔区间与收集种质资源的物种多样性指数的相关性分析发现,三明和龙岩市与Shannon-Wiener多样性指数呈极显著正相关,莆田和龙岩市与Pielou均匀度指数呈现极显著负相关,这与全省农业经济分区有密切关系。通过梳理全省农作物种质资源的多样性,为因地制宜地开发、利用、挖掘全省地方农作物种质资源提供参考和科学依据。

    Abstract:

    During the Third National Crop Germplasm Resource Survey and Collection Action in Fujian province from 2017 to 2022, total 6235 accessions of crop germplasm resources including local crop varieties and their wild relatives were collected. The numbers of vegetables, food grains, fruit trees, economic crops, and forage and green manure crops collected in this action accounted for 33.57%, 25.91%, 24.35%, 14.59%, and 1.57% respectively, and they belong to 83 families, 229 genera, and 313 species. Among these gerplasm resources, 16.04% belong to the Leguminosae faminly with the highest persentage. Different regions and altitudes were relevant to the species types and quantities of crop germplasm resources collected. Among the 9 prefecture level cities in the province, Sanming city had the highest number of germplasm resources, accounting for 20.65%. The number of crop germplasm resources decreased along with the increase of altitude. The number of collections at different altitude was correlated with the number of counties (cities, districts), townships(towns), and villages(streets). The Shannon-Wiener diversity index and Brillouin richness index were the highest at an altitude of 0-200 meters in the six prefecture level cities (Zhangzhou, Fuzhou, Ningde, Quanzhou, Putian, Xiamen) in coastal areas, while these two indexes are relatively high at the altitudes of 200-400 meters, 400-600 meters, and 600-800 meters in three mountainous areas, such as Longyan, Sanming, and Nanping, respectively. Through the correlation analyses of species diversity index in different prefecture level cities and altitude intervals, a highly significant positive correlation was detected between the Shannon-Wiener diversity index and Sanming and Longyan cities, while a highly significant negative correlation was detected between the Pielou evenness index and Putian and Longyan cities, which might be closely correlated to the agricultural economic zones in the province. Thus, by investigating the diversity of crop germplasm resources in Fujian province, this study provided reference and scientific basis for the development, utilization, and excavation of local crop germplasm resources to meet local demands.
