Summary of the invention
The selection that the purpose of this invention is to provide No. 4, a kind of heat-proof cucumber species Jinlv is at producing the active demand of going up different planting form specific breeds, the heat-resisting cucumber variety of seed selection.Breeding solving the problem that cucumber open country in summer kind lacks of new varieties makes the vegetable grower select kind pointed, reduces blindness.
Concrete scheme of the present invention is:
The selection that No. 4, a kind of summer open country heat-proof cucumber species Jinlv:
One is to form good inbred line Q24 high temperature resistant, disease-resistant, high yield with the heat proof material of being introduced by Spain through transformation;
Another is that heat-resisting quantity is good, and product are of fine quality, and disease resistance is good, the inbred line F15 that coordinate force is good;
Inbred line F15 is made female parent, obtain green No. 4 kinds in Tianjin as paternal hybrid with inbred line Q24;
Through 3 years small plot experiments; Through 2 years regional tests and the test of annual product, finally breed green No. 4 new breeds of cucumbers in heat-resisting Tianjin again.This kind can normal growth under summer 36 ℃ of-38 ℃ of conditions, and indoor 40 ℃ of high temperature were handled two days down, and it is not obvious to be injured, and the good heat endurance energy is arranged.
Characteristics of the present invention and technique effect.
Green No. 4 of Tianjin, characteristics are that 1. disease resistance is strong: have parents' resistance originally, anti-blight, downy mildew and powdery mildew.The downy mildew disease index is than No. 4 reductions by 13.4% of open country main breed Tianjin spring, and the powdery mildew disease index reduces by 10.3%, the fusarium wilt incidence of disease low 17.5%.Be suitable for open country growth in summer, have good stable yields performance.2. yielding ability is good: the plant compactness, and growing way is strong; The leaf bottle green; Main climing knot melon is main, and the first female peanut is in 5-6 joint, female flower joint rate about 40%.Later melon is many, from binding, is suitable for dense planting after the side shoot knot melon.Average early yield is than Tianjin spring No. four increases 10-15%, and average gross yield is than No. four increases about 10% of Tianjin spring, and output per hectare can reach 75000 kilograms.3. commodity is good: sugar-preserved gourd is straight, and is long about 35 centimetres, the melon bottle green, and the rib knurl is obvious, and single melon weighs about 220 grams, and melon is short, and the pulp light green, matter is crisp, flavor is sweet, product are of fine quality.
Embodiment
The technical scheme of the seed selection that No. 4, heat-resisting new cucumber species Jinlv
Collect a large amount of domestic and international variety sources, taked multiple breeding method, prepared a large amount of hybrid combination, small plot experiment, regional test, production test have been carried out, bred Tianjin green No. 4, characteristics are that 1. disease resistance is strong: have parents' resistance originally, anti-blight, downy mildew and powdery mildew.The downy mildew disease index is than No. 4 reductions by 13.4% of open country main breed Tianjin spring, and the powdery mildew disease index reduces by 10.3%, the fusarium wilt incidence of disease low 17.5%.Has good stable yields performance.2. yielding ability is good: the plant compactness, and growing way is strong; The leaf bottle green; Main climing knot melon is main, and the first female peanut is in 5-6 joint, female flower joint rate about 40%.Later melon is many, from binding, is suitable for dense planting after the side shoot knot melon.Average early yield is than Tianjin spring No. four increases 10-15%, and average gross yield is than No. four increases about 10% of Tianjin spring, and output per hectare can reach 75000 kilograms.3. commodity is good: sugar-preserved gourd is straight, and is long about 35 centimetres, the melon bottle green, and the rib knurl is obvious, and single melon weighs about 220 grams, and melon is short, and the pulp light green, matter is crisp, flavor is sweet, product are of fine quality.And supporting culture technique and breeding technique have been formulated.
