百蜜系列南瓜品种性状调查与分析

THE INVESTIGATION AND ANALYSIS ON THE TRAITS OF SERIOUS BAIMI PUMPKIN VARIETY

以蜜本南瓜为对照,对河南科技学院南瓜课题组培育的百蜜1号、百蜜2号、百蜜3号、百蜜4号南瓜品种进行性状调查。结果表明:百蜜1号比对照表现早熟,蔓粗度较小,叶柄较短,瓜形指数大,固形物含量低于对照,熟后质地稍差,但其坐果性好;百蜜2号第1雌花节位出现最晚,叶面积最大,叶柄最长,亩产最高,比对照增产39.1%,固形物含量小于对照;百蜜3号生长势强,第1雌花出现较晚,雌花间隔数小于对照,蔓粗度最小,叶面积最小,固形物含量最低与对照达到显著水平,亩产比对照增产33.5%,综合品质较好;百蜜4号蔓粗度最大,节间长度最短,瓜形指数小于对照,固形物含量最高,综合品质较好,是较好的食用品种。

Making the MiBen as the control, the experiment investigated and analyzed the characters of BaiMi 1, BaiMi 2, BaiMi 3 and BaiMi 4 which cultured by Henan Institute of Science and Technology pumpkin Research Group. The results indicated that BaiMi 1 was a variety of earlier maturity than CK, its stem roughness was smaller, its petioles was shorter, its melon fraetal exponent was big, solids content was more below than the CK, its edible qualities were relatively poor, but its fruit - bearing was good. The node of female flowers of BaiMi 2 appeared the latest, leaf area of BaiMi 2 was the largest, and its petiole was the longest and the yield was the high- est, and its yield per mu was higher 39.1% than the CK, and its solids content was more below than the CK. Growth potential of Bai- Mi 3 was strong, the node of female flowers appeared later, and interval of the female flowers was less than CK, its stem roughness and leaf area was the smallest, its solids content was the most below and it had reached significance level, its yield per mu was higher 33. 5% than CK, and its comprehensive quality of the fruit was better. The stem roughness of BaiMi 4 was the biggest and the internodes length was the shortest, its melon fractal exponent was smaller than CK, its solids content was the highest, comprehensive quality of the fruit was better, it was a good variety on edible qualities.
