Abstract

The invention discloses a sowing method of pumpkin stock, which comprises the following steps: adopting Chinese round pumpkin in the Shandong province to cross for three generations, separating to purify, identifying to sieve self-crossing YN-3 to grow stably under low-temperature and weak light condition as mother, selecting self-crossing CN-3 of Indian long pumpkin to resist low-temperature, drought and disease as father, crossing to obtain the first-filial generation.

Description

technical field [0001] The invention relates to a seed production method of pumpkin rootstock. Background technique [0002] With the development of science and technology, in the melon and fruit planting technology of modern agriculture, rootstocks are often used to achieve disease resistance and disease prevention through grafting and root replacement. At present, the used rootstock of planting melon and fruit is roughly divided into three kinds: 1, make rootstock with black pumpkin, and it can only be used as the rootstock of cucumber, and the scope of application is narrow; The disclosed "breeding method of first-generation hybrid of watermelon rootstock" and Chinese patent No. 200310108868.5 disclosed "breeding method of special hybrid rootstock for facility watermelon wilt control" cultivated gourd stock, although this gourd stock can be used as watermelon, cucumber 3, use hybrid pumpkin as stock, although this hybrid pumpkin stock can be used as the stock of cucumber...
