苦瓜资源引进及品种适应性研究

Study on the introduction of bitter gourd germplasm resources and variety adaptability

【目的】研究洞庭湖区苦瓜种质资源引进和品种适应性。【方法】引进10种苦瓜资源在洞庭湖区开展品种适应性试验,对苦瓜19项主要农艺性状进行评价鉴定和相关性分析。【结果】茎粗、节间长、叶片长、叶片宽、叶柄长、第一雌花节位、瓜纵径、瓜横径、瓜肉厚、单瓜质量、单株瓜数和产量等性状均表现出差异性;单瓜质量与瓜纵径、节间长呈显著正相关,节间长与茎粗呈显著正相关;瓜肉厚与叶柄长呈显著负相关。【结论】4号苦瓜在洞庭湖区的适应性表现最佳,9号苦瓜可作为特色资源引进用于苦瓜新品种选育。

【Objective】To provide a theoretical basis for the introduction of bitter gourd germplasm resources and the identification of variety adaptability in Dongting-Lake area.【Method】This study introduced 10 bitter gourd resources to carry out variety adaptability test in Dongting-Lake area,and evaluated and identified their 19 main agronomic traits and correlation analysis.【Result】There were differences in stem diameter,internode length,leaf length,leaf width,petiole length,first female flower node,melon longitudinal diameter,melon transverse diameter,melon flesh thickness,single melon weight,melon number per plant and yield.The single fruit weight was significantly positively correlated with the longitudinal diameter and internode length,and the internode length was significantly positively correlated with the stem diameter.There was a significant negative correlation between flesh thickness and petiole length.【Conclusion】No.4 bitter gourd had the best adaptability in Dongting-Lake area,and No.9 bitter gourd could be introduced as a characteristic resource for the breeding of new bitter gourd varieties.
