Breeding method of compact mung bean

Abstract

The invention discloses a compact mung bean breeding method, which is used for solving the problems that the bred variety of an existing breeding method is high and the plant is large, the plant shape is loose, planting density is low, relatively late in the maturity is relatively late and the yield is low caused by low test densities of selective nurseries and mung beans by greatly improving the test densities of the selective nurseries and the mung bean, increasing selective pressure, and breeding the mung bean variety which is compact in plant shape, early in maturity and high in yield. According to the compact mung bean breeding method, the mung bean yield per unit area can be improved by 30%; the growth period of the mung bean variety is shortened; two important characters of early maturity and high yield are combined into one variety; the mung bean variety is relatively intensive to pod and is suitable for mechanized harvesting; and the lodging-resistance capability is improved.

Description

technical field [0001] The invention relates to the field of mung bean breeding, in particular to a compact mung bean breeding method. Background technique [0002] The research on mung bean breeding in my country started relatively late. In the past, local varieties were mainly planted all over the country. Most of the mung bean varieties planted in the northeast production area were vine and semi-vine bean varieties with low planting density, generally 6000-7000 plants / mu, and low yield; Huanghuaihai production area Both trailing and upright varieties are planted, with lower planting densities and lower yields. [0003] In the mid-1980s, the Chinese Academy of Agricultural Sciences introduced Zhonglu No. 1 from the United States. Due to its high yield and good disease resistance, it was widely popularized in the Huanghuaihai region. However, this variety has higher plants and looser plant types. The planting density is generally around 10,000 plants. The maturity period is...

Problems solved by technology

[0007] The purpose of this invention is to provide a kind of compact mung bean breeding method, by greatly improving the density of seed selection nursery and mung bean test, increasing the selection pressure, breeding compact, precocious, high-yielding mung bean varieties, to solve the problem of existing breeding In the method, due to the low density of the seed selection nursery and the mung bean test, the cultivated product has large plants, loose plant type, low planting density, late maturity, and low yield.
