摘要
对庆阳市温室栽培的11个绿皮密刺黄瓜品种的农艺性状进行了分析,结果表明:各性状变异系数由大到小依次为侧枝数、第1雌花节位、蔓长、最大叶宽、最大叶长,且各主要农艺性状均呈正相关。采用卡方距离、离差平方和法进行聚类分析,将11个参试品种聚为3类,Ⅰ类为津研1、2、3、4、6、7号,Ⅱ类为津优3、12、32、35号,Ⅲ类为新7号品种。
Agricultural characters on eleven kinds of green cucumber varieties with dense thorn was observed and anal- ysised in greenhouse of Qingyang City.

The results also indicated that eleven races is an- alyzed as three types by chi-square test and sum of squares of deviations which the first is Jinyan 1, Jinyan 2, Jinyan 3, Jinyan 4, Jinyan 6, Jinyan 7; the second is Jinyan 3, Jinyan 12, Jinyan 32, Jinyan 35; the third is xin 7.
