[0041] Example 1 Breeding method of small seed pumpkin rootstock varieties

[0042] 1. The method for breeding small seed pumpkin rootstock varieties of the present invention includes the following steps:

[0043] (1) Obtained by genetic law

[0044] Through the investigation of pumpkin germplasm resources, combined with the breeding goals, two materials NMO83 and XBZM with significant difference in grain size were selected, and their thousand-grain weights were 110g and 160g respectively; the two were crossed as parents to obtain hybrids F1 and RF1. Then F1 was self-crossed to obtain F2 generation, and F1 and NM083 were backcrossed to obtain BC1 generation; NMO83, XBZM, F1, RF1, F2, and BC1 were planted simultaneously in the next season; after the fruit was mature, the thousand-seed weight of seeds was checked, and the results were F1 and RF1 The thousand-grain weights of squash are 178g and 214g, which are relatively close to the large-grain parent XBZM. Both the F2 population and...

[0114] The following is a summary of the results of the 2016-2017'Sizhuang 10' variety comparison test

[0115] 1 Test overview

[0116] In order to investigate and identify the adaptability, disease resistance, grafting performance, watermelon quality and yield of the newly bred small-seed pumpkin rootstock variety'Sizhuang 10', the'Almighty Tiejia' rootstock (CK1) and 'Zaojia' self-rooted seedling (CK2) was used as control. From 2016 to 2017, multi-point tests were carried out for many years. The test sites are Ningbo High-tech Agricultural Technology Experimental Park (Ningbo), Pinghu Lvye Fruit and Vegetable Cooperative (Pinghu) and Deqingtian Agricultural Technology Co., Ltd. (Deqing).

Abstract

The invention discloses a breeding method for small grain type pumpkin stock variety, and belongs to the field of melon stock variety breeding. The breeding method comprises the following specific steps: researching the genetic rules of pumpkin seed size and seed melon quantity in a unit according to segregation population, and selecting parents and apolegamic combination according to the geneticrules. The male parent is a stable selfing line through seven-generation selfing screening of stock variety ''Huofenghuang'' introduced from Shandong, and has the characteristics of relatively developed root system, medium growth vigor, oblate fruit, earthy yellow peel and high drought tolerance; the female parent is a stable selfing line through six-generation selfing screening of stock variety ''Xuebai'' grafted from Shandong watermelon, and has the characteristics of approximately circular fruit, developed main roots, orange peel, prematurity and preferable high temperature resistance and low temperature resistance; and the variety is obtained through apolegamic cross combination of the male parent and the female parent. The obtained variety is small in seed leaves, is applicable for 50-hole plug seedling, high in resistance for watermelon fusarium wilt, ordered in germination, unlikely for excessive growth, long in grafting period, convenient for grating and high in grafting survival rate.

Description

Technical field [0001] The invention belongs to the technical field of melon rootstock breeding, and particularly relates to a method for selecting and breeding small-seed pumpkin rootstock varieties. Background technique [0002] Melon grafting cultivation has a history of at least 3000 years in our country. In 100 BC, Chinese agronomist Fan Shengzhi's "The Book of Pan Sheng" contains records of the production of large pots. Japan began research on the prevention of diseases by grafting melons in 1925. By the 1990s, the grafted cultivation area of ​​melons and vegetables in Japan had reached 60% of the total area and more than 90% of the protected cultivation area. The research and application of melon grafting cultivation in my country began in the 1970s, but the development was slow. Since the 1980s, due to the continuous expansion of watermelon cultivation area and shortening of the crop rotation cycle, fusarium wilt has become more and more serious. It has become a major ob...
