Embodiment 1

[0023] 2006: Planted Doujiao 38, Binzhidou No. 1, Shengfengzhongdou 31, Moshidou 4 soybean varieties with different maturity stages and 8 different ecological types of wild soybeans (WFLSW-2, WFQSW-2, WFJPW- 1. ZBHPW-1, DYKSW-3, QDJSW-3, DYKYW-4, BZZYW-4), using artificial pollination, the sowing time is shown in the table below.

[0024]

[0025] See the table below for hybridization results.

[0026]

[0027] Plant the first-generation hybrid seeds harvested in the above table, harvest the second-generation hybrid seeds, plant 250 to 350 second-generation hybrid seeds, and observe the properties. The results are shown in the table below.

[0028]

[0029] Because Doujiao 38 is the female parent and DYKSW-3 is the male parent, the offspring of the cross are upright and have many branches, so this combination was selected for further self-purification.

[0030] The F1 hybrid seed of "Doujiao 38 (Min 2 x Wei 4) as the female parent and wild soybean DYKSW-3 as the male...

Abstract

The present invention relates to the technical field of soybean variety breeding, in particular to a breeding method for forage-type soybeans: take Doujiao 38 as the female parent and wild soybean DYKSW-3 as the male parent, and perform hybridization to obtain a first-generation hybrid seed, according to the pedigree method Carry out multi-generation selfing and purification, and select a single plant that is upright and has a large number of branches to save seeds during selfing. The selected variety has completely changed the growth characteristics of its male parent, which grows upright, with branches starting from the base of the stem, with a large number of branches, and also has the characteristics of a large amount of leaves from the male parent, and pods start from the base of the stem. The pods are dense and solid, and it is a high-quality, medium-yield annual forage soybean variety with high feed value.

Description

technical field [0001] The invention relates to the technical field of soybean variety breeding, in particular to a method for breeding grass-type soybeans. Background technique [0002] Because of its high nutritional value and good palatability, leguminous forage has become a high-quality forage grass for herbivorous livestock, and it is an important component of the diet of herbivorous livestock. However, there are few high-quality legume forage varieties in my country, and the varieties suitable for planting legume forage in East China are even more There are very few of them. Therefore, it has become a top priority to cultivate leguminous forage varieties with high quality, high yield and strong adaptability. [0003] The annual wild soybean is widely distributed in the Yellow River Delta region of Shandong Province. It has the characteristics of soft stems, large leaves, rich nutrition, high yield of fresh grass, good palatability, high feeding value, resistance to dise...
