Embodiment 1

[0040] Embodiment 1, the method for collecting sweet potato germplasm resources in the field and processing

[0041] Sweet potato seedlings were collected from Hujiashan, Shitozui Town, Yingshan County, Huanggang City, Hubei Province, and planted in the experimental base of the Institute of Food Crops, Hubei Academy of Agricultural Sciences.

[0042] 1. Field collection of seedlings

[0043] From Hujiashan, Shitozui Town, Yingshan County, Huanggang City, Hubei Province, choose Eshu 11 sweet potato seedlings that are free from diseases and insect pests and grow robustly, and the cutting length is 30-40cm (distance from the top), as sweet potato seedlings.

[0044] According to the census requirements, on-site GPS positioning, digital photography, sorting, binding, and listing. And establish original archives for the collected germplasm resources, detailing the material name, basic characteristics, collection place and time, collection quantity, collection person, etc.

Abstract

The invention discloses a treatment method of sweet potato germplasm resources collected in the field. The treatment method starts with the links of field collection of seed seedlings, seedling treatment and packaging, hydroponic preservation of seed seedlings, transportation of the seed seedlings, isolation transplanting, post-planting management and the like. With the method, the survival rate of the sweet potato germplasm resources collected in the field is greatly increased, the spread of sweet potato diseases and insect pests is effectively avoided, and field collection and treatment of the sweet potato germplasm resources are realized; a foundation is laid for enriching sweet potato germplasm resources and breeding of breakthrough varieties of sweet potatoes.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for processing sweet potato germplasm resources collected in the field. Background technique [0002] Sweet potato (Ipomoea batatas (L.) Lam.) is an important root crop for food, feed, industrial raw materials and new energy in the world. my country is the largest sweet potato producer in the world, with an annual planting area of ​​5.5 million ha 2 , the yield of fresh potato is about 1.2×10 8 t, accounting for 60% and 85% of the world's total sweet potato planting area and total production, respectively. The genetic basis of sweet potato is narrow, and the damage caused by diseases, insect pests and viral diseases is serious, which seriously restricts the genetic improvement of sweet potato varieties. Many research results at home and abroad show that the overuse of core parents leads to low genetic diversity among sweet potato varieties, narrow genetic basis, ...
