Breeding method for variety of zizania latifolia

Abstract

The invention discloses a breeding method for a variety of zizania latifolia. The method is designed by adopting block experiments, double-season zizania latifolia and single-season zizania latifoliaare separately provided with block experiments, control groups are subareas individually arranged according to a local planting habit and management method, variety small areas are introduced in the block experiments, the variety small areas are randomly distributed, repetition is performed for three times, a seedling emergence period, planting time, tillering time, stem swelling start time and aharvest period of experimental varieties are recorded, field performance traits, occurrence conditions and prevention and control effects of pests and diseases, and product commodity traits of the experimental varieties are observed and recorded, crude zizania latifolia is harvested in a same harvest season in each area in batches, yields are combined, and a yield in each area is counted, and a main cultivation variety and a combination variety of the zizania latifolia suitable for large-scale production are screened. According to the method disclosed by the invention, through introduction, experiments and demonstration of a novel variety of the zizania latifolia and research of agronomic measures and environmental factors such as a fertilization technique, a cultivation density, cultivation time and water level regulation on the yield, quality and marketing period of the zizania latifolia, the novel variety of the zizania latifolia suitable for local planting is introduced and screened.

Description

technical field [0001] The invention relates to a breeding method for screening wild rice varieties more suitable for local planting, so as to update and enrich local wild rice variety resources. Background technique [0002] Zizania latifolia (Griseb.) Stapf, also known as wild rice, watermelon, bamboo shoots or mushroom head, is a perennial swamp herbaceous plant of the genus Gramineae. Zizania wild rice has great economic value. After being parasitized by smut fungus, the tender stems at the base of the stalks become thick and tender, called zucchini, which is a delicious vegetable; It is a wintering place for fish and a pioneer plant for embankment construction. In ancient times, wild rice grows normally and bears fruit in autumn. It is called Diaohumi and is one of the six grains. Later, it became deformed due to parasitism of smut and could not bloom and bear fruit, so it became a vegetable. [0003] Zizania as a characteristic aquatic vegetable is widely planted in ...

AI Technical Summary

Problems solved by technology

[0004] Hanzhong City is located in the hinterland of the Qinba Mountains, which is the border between the north and the south of my country's climate. The planting of Zizania has long been recorded. However, due to insufficient attention to the cultivation of Zizania, the production of Zizania has not been industrialized and scaled, and the planting area has continued to shrink

At present, there are problems such as mixed sources of varieties, serious degradation of varieties, and low level of planting technology in the development of water bamboo planting.
