Introduction to the characteristics of the new high-yield soybean germplasm MN413
Origin and breeding process MN413 new soybean germplasm was developed in 1990 by sexual hybridization using the high-yield line MS8118 (subjected to plasma treatment N50 times, 30Kev) as the female parent and Yudou No. 10, and through bulk population and pedigree selection, it was stabilized in 1997 and named MN413 (Mengning 413). In 1998, it participated in the institute's variety comparison and identification, with an average yield of 239.7 kg per mu, an increase of 18.5% over Zhongdou 19, and in a 0.4-mu propagation field the yield reached 274 kg per mu; in 1999, it participated in multi-location trials in the province

Noteworthy specific germplasm of wild apricot (Prunus sibirica) in Chaoyang, Liaoning
Abstract: We surveyed apricot germplasm resources in Chaoyang City, Liaoning Province, and identified 11 specific germplasms, including 3 kernel-use germplasms, 4 landscaping germplasms, and 4 germplasms pending further identification. These new germplasms not only enrich the apricot germplasm resources of Liaoning Province, but also lay a material foundation for breeding new cultivars. Keywords: apricot germplasm, kernel use, landscaping. Chaoyang City, Liaoning Province is one of the main apricot production areas in China, with a long history of apricot cultivation. In the past, local wild apricots were mostly propagated by seed, and the genetic differences of wild apricot at the three levels of individual, stand and provenance were fully differentiated and accumulated.

Introduction to the Cotton "Dong A" Genic Male Sterile Germplasm Resource
In 1972, a male sterile cotton plant was discovered in the field, and after 3 years and 6 seasons of research, the cotton "Dong A" genic male sterile germplasm was successfully developed. Its male sterility trait is mainly controlled by a pair of recessive nuclear genes. It has the characteristics of stable inheritance of male sterility, easy transfer, strong combining ability, a wide range of restorer lines, a population male sterile plant rate of about 50 percent, and 100 percent male sterility per individual plant. It also has good yield potential and wide adaptability. Using the Dong A genic male sterile germplasm, 1 derivative male sterile line was developed. Among them, several derivative male sterile lines were further combined and screened to produce 12 hybrid

What kind of woody plant is the purple-spotted peony? Let's get to know it
The purple-spotted peony (Paeonia rockii) is a plant endemic to China and a precious floral germplasm resource, with its root bark used for medicinal purposes. The purple-spotted peony is distributed on slopes under secondary summer-green broadleaf forests or in shrubland, as well as in rock crevices. It is of certain significance for studying the phylogeny of the genus Paeonia and for breeding new peony cultivars. A nature reserve has been established on Mount Taibai in Shaanxi, and it should
