Chinese and foreign scientists join hands to decipher rape polyploid genome
A few days ago, led by the International Rape Sequencing Consortium, the genome sequencing of Brassica napus was completed for the first time. This is the first time in the world that the complex genome of a traditional polyploid crop has been completely sequenced and assembled, and its system comparison with its parent species has been completed.

Polyploid Robinia pseudoacacia, a new tree species suitable for growing in barren soil
A sapling which is less than 10 centimeters long and only looks like a pea seedling, planted on a barren land where nothing grows, can leap up to more than 3 meters high in a year. This is based on the introduction of foreign tree species by the Luyuan Seedling Research and extension Center of Changyi City, Shandong Province and the experts of Beijing Forestry University. a new type of tree species, multiple system locust, which is suitable for planting in western China, has been successfully cultivated by plant tissue culture technology. It has become a popular "golden tree seedling" because of its excellent resistance to drought, salt and alkali and barren.

Tetraploid Robinia pseudoacacia
Tetraploid Robinia pseudoacacia is one of the excellent clones of polyploid Robinia pseudoacacia introduced from abroad, which has been selected by painstaking research and experiment for many years. Tetraploid Robinia pseudoacacia is an artificially induced tetraploid plant with fast growth, large leaves and large biomass. Its leaf width is more than 2 times that of common Robinia pseudoacacia. Compound leaf dry weight, single leaf dry weight and total leaf dry weight are 1.5 times or more than that of common Robinia pseudoacacia. Compared with common Robinia pseudoacacia, tetraploid Robinia pseudoacacia has thicker crown, stronger branches and stronger photosynthetic capacity. Quadruple

Introduction of a new variety-tetraploid Robinia pseudoacacia
Tetraploid Robinia pseudoacacia, a new polyploid variety of Robinia pseudoacacia, originated from South Korea and was introduced into China in recent years. At present, five series numbers have been introduced and cultivated, which can be divided into two types: fast-growing wood type and feed type. According to the analysis of the experimental results, compared with the common Robinia pseudoacacia clones, the main characteristics of tetraploid Robinia pseudoacacia clones are as follows: the fast-growing wood type of ① is similar to that of common Robinia pseudoacacia clones, but the rapid growth is more obvious. The height of annual grafted seedlings can reach 3 meters, the ground diameter is 3.5 cm, and the height of 3-year-old trees is 5 meters to 7 meters, and the DBH is 6 cm to 9 cm. The 18-year-old tree is 19 meters tall, with a DBH of 24.5 cm and a single tree volume of 0. 5 cm.
