High-yield high-quality sesame hybrid

Abstract

The invention discloses high-yield high-quality sesame hybrid. The high-yield high-quality sesame hybrid is mainly characterized in that typical trematodon hybrid sesame seed is cultivated by the steps of: with selected variation single strain 2001A of yiyang white sesame as a female parent and selected D1-33 as a male parent, carrying out pure-breeding by mutation; carrying out distant hybridization; and carrying out selective breeding by a multi-year pedigree method. The single-plant hybrid sesame has a few branches, tall and strong plant, extra long capsules, short internodes, and psophocarpus capsules with the yield per unit area of 100 kilograms to 150 kilograms; the flowering stage is about 45 days and the overall growth period is about 100 days; the plant is eugenic, regular, strong, full of delayed effect, not provided with premature senescence, strong in disease-resistance, drought-resisting and strain-resisting; the seed coat is pure white; the oil yield is as high as 58%; the oil is thick and scented; the content of the crude fat is 59.2%; the content of crude protein is 26.4%. The high-yield high-quality sesame hybrid disclosed by the invention is awarded with the first prize of technological innovation by Qianjiang People's Government of Hubei Province in 2003.

Description

technical field [0001] The invention relates to a high-yield and high-quality sesame hybrid, which is specially used for the breeding of high-yield sesame hybrid and belongs to the field of crop breeding. Background technique [0002] Sesame is an annual herbaceous plant of the family Linaceae and is one of the oldest oil crops. Because of its high oil content, it has the reputation of "Queen" of oil crops. Sesame has extremely high nutritional value, and its chemical composition is mainly unsaturated fatty acids, with oleic acid and linoleic acid accounting for more than 80%. Sesame is also an important source of plant protein. Its protein is globulin, accounting for 39-48% of the defatted meal. The protein contains 8 kinds of amino acids needed by the human body, and the composition is complete, especially the content of sulfur amino acids is high. In addition, every 100 grams of sesame contains 14.4 grams of carbohydrates, 564 mg of calcium, and 50 mg of iron. It is als...

Problems solved by technology

[0003] However, in recent years, due to the lack of high-yield and high-quality sesame varieties, the sesame varieties promoted in production have poor disease resistance and water resistance, and the yield is low and unstable. The economic benefits of planting sesame are not as good as planting other economic crops, which affects the enthusiasm of farmers for planting.
