Description

New soybean variety having super-high productivity characterized by high number of seeds per plant}

The present invention relates to a new plant variety of ultra-soybean beans, more specifically, it is obtained by artificial breeding using SS2-2 varieties derived from Sinpung bean No. 2 as a model as a model and 'Pungsan namul bean' varieties. It is related to a new variety of soybean plants with a large number of mesenchymal and branched trees and a significant number of seeds per individual.

In recent years, the global food crisis has been escalating, and “agflation” has become a reality due to food inequality between countries. In fact, Korea's food self-sufficiency rate is only 28%.

This food problem was also highlighted in the Fifth World Crop Society in Jeju in 2008. The government is committed to coping with the growing global food crisis and improving the quality of human life through continuous food productivity development and crop science development. It was adopted the 'Declaration of Food Security Jeju Declaration,' which is the contents.

The Declaration recognizes that "current crop production cannot be responsible for global food security, so crop production must continue to expand." Crop production and varieties are well adapted to adverse climate changes such as global warming and water shortages. We expect that we will be able to solve the global food crisis, and we need to make continuous efforts to develop sustainable and eco-friendly agriculture. To this end, we will make a global partnership for food security and poverty reduction by expanding science, technology, financial support and education through bold investment. It must be strengthened continuously.

In general, beans are believed to have originated from the land of Goguryeo, Manchuria and the Korean Peninsula, and their cultivation history is believed to be over 4,000 years. In the Orient, beans have been called five grains with blood, millet, crude and sorghum and together with rice and barley, it is a major food crop in our diet. In particular, soybeans have played a very important role in supplying high quality vegetable protein to various Korean foods, which have long been lacking protein sources. Soybeans are widely cultivated from the tropics to the northern part of temperate zones, and their main origin is 30-40 ° north latitude in Asia and the United States and 10-30 ° south latitude in South America.

The soybean breeding goal in Korea has clearly shifted from the improvement of the yield of jangbean soybeans in the 1990s to the diversification of use and the high quality. Through this, the use has been diversified into soybean, tofu, herb beans, green beans, rice beans and rice cakes, and has achieved numerous results in terms of varieties such as progress in processing suitability and quality improvement.

However, although Korea is a strong source of soybeans, the soybean self-sufficiency rate is about 11% as of 2008, and the unit productivity (quantity per 10a) is also about 175kg, which is much lower than that of major countries such as the United States. This is urgently needed.

The present invention has been made in accordance with the above requirements, the present invention is a large variety of super-soybean soybean varieties with a large intestine, a large number of major transverse and branching, the number of seeds per individual significantly improved unit yield The purpose is to provide.

In order to achieve the above object, the present invention is obtained by artificial breeding using 'Pungsan Namul Bean' varieties as a model and SS2-2 varieties derived from Shin Paldal Bean No. 2 as a main body. It is related to a new variety of soybean plants with a large number of meridians and branches and a significant number of seeds per individual.

The present invention is a strain obtained by artificially crossing the `` Pungsan Namul Bean '' varieties (♀) and SS2-2 varieties (♂) derived from New Paldal Bean No. 2, the number of individuals per individual is 127 to 562, the number of branches per individual 8 to 13 It is characterized in that the unit quantity is 603 kg / 10a.

In addition, the new soybean plants of the present invention is characterized in that the plant is 105 to 113 cm tall.

In addition, the new soybean plant of the present invention is characterized by a large number of main diameter of the plant 21 to 27, the number of branches 8 to 13.

New varieties of soybean plants according to the present invention are super-large soybean plants that can improve unit yields by 50% or more during large-area cultivation, even if they take up a lot of space in terms of light utilization because of their large length. In addition, it is expected to contribute greatly as a useful genetic resource for nurturing a variety of super-plural new varieties.

1. Development process (cultivation of hybrid species)

     SS0404-T5-76 is a variety of bean varieties for herbaceous varieties. It is modeled after 'Poongsan Herb Bean', which is the most cultivated in Korea. It is obtained by artificial breeding. Particularly, SS2-2, which is a major part, has the advantage of being able to fix more nitrogen in the air because it has ultra-multi-root characteristics.

     2. Selection and fixation process

As shown in FIG. 2, parental copies were bred in March 2004 to obtain seed F ₁ , and then F ₄ lines were grown in F ₂ from April 2004 to July 2005. Thereafter, 224 F ₅ seeds were sown in August 2005, and F ₆ strains were sown in 2006, and 86 F ₇ seeds were finally harvested in January 2007. The plant was then cultivated at Seoul National University Suwon Farm in 2007-2008. Finally, in the fall of 2008, we selected SS0404-T5-76, the most excellent system among 86 F ₈ generations. SS0404-T5-76 is a finite new breed and is a late-growing species that is slightly later than Pungsan Herb Bean. The roots show very high roots of many roots, especially the large intestine, and the number of seeds per individual, but also strong in dobok (see Fig. 1).

  On the other hand, the cropping method and cultivation management in the 1 and 2 process was mostly in accordance with the Rural Development Administration standard agricultural textbook (bean cultivation), but the cultivation was adjusted to 80cm.
