Embodiment 1

[0020] 1000 plants of NC297 flue-cured tobacco and French wild grape were planted in the red tobacco flue-cured tobacco base in Mile County, Yunnan Province, and the comparison tests of grafting affinity, plant growth characteristics after grafting, disease and insect resistance ability and quality of flue-cured tobacco leaves were carried out. The specific operation steps are as follows:

[0021] 1. Select the rootstock and scion: the rootstock should be French wild grape varieties. It is required to choose a good location, a robust rootstock shoot, no pests and diseases, and the distance between the cut and the bud should not be less than 5 cm. The diameter is more than 0.5 cm; the scion is selected from the flue-cured tobacco variety NC297, and the seedling age is required to be about 50 days, the stem height is 5-7 cm, the stem circumference is 0.5-1 cm, the leaf buds are full, and there is no damage to the tobacco seedlings by diseases and insect pests.

Abstract

The invention discloses a method for improving the variety of NC297 flue-cured tobacco. The method comprises the steps of: selecting French wild grape as a tree stock and a seedling of NC297 flue-cured tobacco as a scion; performing grafting by adopting the tongue grafting method in the first ten-day period of April, wherein clefts of the tree stock and the scion are ligules and are about 1cm in length, the ligules are matched, the ligule of the scion is intersected with that of the tree stock and the ligulesa lean against each other; and after grafting and survival, transplanting the plant to field. According to the invention, the French wild grape and the NC297 flue-cured tobacco are subjected to distant hybridization initiatively. Through grafting, the resistance to disease and pest ofthe novel plant is improved. In addition to characteristics of the variety of NC297 flue-cured tobacco, the novel plant has unique sweet flavor of the French wild grape and the amount and quality of sweet smell of tobacco are improved.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco cultivation, and in particular relates to a method for improving NC297 flue-cured tobacco variety through distant hybridization. Background technique [0002] The NC297 flue-cured tobacco variety belongs to the dicotyledonous plant family Solanaceae and the genus Nicotiana in plant taxonomy. It is an annual herb plant and is a hybrid F1 variety bred by the American Golden Leaf Seed Company in 1998. Introduced to China in 2006, the selection and breeding of flue-cured tobacco varieties for applicability first started in Yunnan. After several years of experimentation and exploration, important data such as NC297 growth and development, regional suitability, field performance, appearance quality of tobacco leaves, chemical composition, sensory evaluation and industrial verification and preliminary supporting production technology have been obtained. Judging from the results, NC297 has goo...
