摘　　要：以本所育成的10个花生新品系及对照种泉花10号为材料,分别在水田和旱地两种生态条件下种植,并对主茎高、单株干果重、百果重和小区产量等18个农艺性状进行了比较。结果表明,莆系花生在水田和旱地不同生态条件下种植:①除饱果率外,其余17个农艺性状水田与旱地存在显著或极显著差异,总体表现旱地好于水田;②除饱果数、饱果率和单株干果重外,其余15个性状参试品种间有显著或极显著差异;③对主茎高等11个主要性状相关分析结果,在水田有59.3%性状显著相关,在旱地有63.0%性状显著相关,其中两地均显著相关的性状占总数37.0%。通过花生在水田和旱地两种生态环境下农艺性状差异比较及其它们之间的相关性研究,对莆系花生品种生态适应性进行了初步分析,为花生遗传育种和新品种推广提供科学依据。Eighteen agronomic characters including main stem height, dry yield per plant, weight of 100 pods and plot yield were compared among ten new peanut varieties and control variety Qianhua No. 10, in dry land and paddy field respectively. The results indicated that the followings about Pu-series peanut varieties under two different soil types： ① among the eighteen agronomic characters investigated , all are significant difference or remarkable difference except number of plump pots per plant, and they were better in dry land than in paddy field conditions; ② other fifteen agronomic characters were significantly or remarkable different among the varieties tested, except number of plump pots, percent of plump pots and plot yield per plant; ③eleven characters e.g. main stem height, analysed result showed that 59.3% and 63.0% of the characters were significantly correlative respectively under dry land and paddy field conditions, and 37.0% of them were significantly correlative both in the two soil types. These results may offered some scientific foundation for peanut breeding and extension of new varieties.
