Introduction to New Dual-Purpose (Medicinal and Tea) Honeysuckle Varieties 'Jincuilei', 'Yincuilei' and 'Baiyun'
The Hunan Academy of Forestry and the Longhui County Forestry Bureau jointly carried out the breeding of new honeysuckle varieties, and for the first time discovered in Lonicera macranthoides an excellent variant type of honeysuckle whose corolla never opens during the flowering period. After 8 years of breeding, two new bud-type varieties, 'Jincuilei' and 'Yincuilei', were developed with excellent flower quality, high yield, high chlorogenic acid content (the component in honeysuckle responsible for antibacterial and anti-inflammatory effects), and strong resistance. At the same time, a new semi-open-flower-type variety 'Baiyun' with high yield and resistance to powdery mildew was bred. The notable characteristics of these varieties are: the flower tube surface is smooth and hairless, and each

What are the main cultivated mushroom varieties in China?
1. Mushroom strain 27962796: The mushrooms are round and regular, with no scales, a semi-membranous partial veil ring, thick caps, and medium-thick, fairly straight and short stems. The tissue is firm, the gills are tightly packed and pale in color, and there is no stem detachment. Each kilogram contains 90-100 mushrooms, and the fresh mushrooms have a relatively high water content, with a pre-cooking yield of 65%. This strain is suitable for cultivation on a double-fermented compost. The mycelium growth rate is medium to fast. It is relatively tolerant of fertilizer, moisture, and high temperatures. Its fruiting period is 3-5 days later than that of common mushroom strains. The mycelium has strong soil-creeping ability and strong knotting ability, and the mushroom formation rate is high. The mushrooms are basically solitary.

What are the new large-flowered carnation varieties?
1. Variety introduction: In the late period of the "Ninth Five-Year Plan", the Flower Research Institute of the Yunnan Academy of Agricultural Sciences undertook the provincial Science and Technology Department's science and technology tackling project "Breeding of New Large-flowered Carnation Varieties", and has bred a group of new cut-flower carnation varieties (lines). Some of the new varieties, after small-scale trial planting by flower growers, have shown good production suitability and marketability. Four applications for new carnation variety rights were filed with the Plant Variety Protection Office of the Ministry of Agriculture of China. Among them, compared with Master, currently the foreign variety of the same red series with the largest planting area, Yunhong No. 1

Rice cultivation in cold regions requires water-saving irrigation, selection of improved varieties, making the most of accumulated temperature, and growing strong seedlings
Heilongjiang Province is located in a high-cold region, where heat and water resources are relatively scarce, annual atmospheric precipitation is extremely unevenly distributed, spring is windy with little rain, and drought is quite severe. The author discusses how to achieve water-saving, high-quality, and high-yield rice cultivation in cold regions. 1. Selecting excellent varieties is the prerequisite for ensuring high-quality and high-yield rice. The varieties that rice farmers plant directly affect the quality and yield of rice. Therefore, in production, varieties with a suitable maturity period, excellent quality, stable and high yield, and strong stress resistance should be selected. First, select varieties that have passed national approval, been named, and promoted, which can ensure relatively stable rice traits, steady and rising yields, and safe and reliable use; second, introduce varieties with suitable maturity periods according to different accumulated temperature zones, and never introduce varieties across zones; third, pay attention to seed quality, and select first-grade improved seeds with a purity above 98%, a germination rate above 90%, and a moisture content no higher than 14% for production use; fourth, purchase seeds from nationally certified seed companies, research institutes, and agricultural colleges, and eliminate blind planting; fifth, in actual planting, unify varieties as much as possible, plant in contiguous fields, form scale, and achieve industrialized planting.
