According to the principle of gene recombination, the authors combined the local tropical germplasm with PB germplasm, which was rich in disease-resistant, lodging-resistant and drought-tolerant genes, and the integration was used as the innovative strategy for breeding. Inbred-line ＇LSC 107＇ was suc- cessfully bred and the new maize hybrid ＇Wande No.l＇ was bred by crossing ＇LSC 107＇ with ＇Yi 99-19＇. The results showed that the maize hybrid had good performance, including high yield, good stability, high quality, excellent disease re- sistance and lodging resistance, and wide adaptation. So it was adaptable for plant- ing in plain and hilly areas of Sichuan Province. With hybrid recombination between local tropical germplasm and PB inbred lines, the inbred-line had high general com- bining ability and strong adaptability, and the hybrid had high yield, high quality and wide adaptability, and had broad prospects of popularization and application.展开更多

In muhipeint regional test, the average yield of Longli 1 was 2 100. （30 kg/hm2, which was increased by 9.6% compared to Jingle qulnoa. Langli 1 was a mid-late mature quinoa variety. The plant was brcom-shape, with the plant height of 181.2 - 223.6 cm, the growth period of 128 - 140 d, and the branch number of 23 - 27. The seeds were round pill shaped, with 1 000-grain weight of 2.40 -3.46 g. The contents of crude protein, fat, proline and total phosphorus in seeds were 171.5 -187.8, 56.5 -59.3, 5.5 -6.9 and 4.5 -6.8 g/kg, re- spectively. I_ongli 1 presented resistance against downy mildew and leaf spot, with strong disease-resistant ability. In multipeint regional test and production test, Longli 1 displayed lodging resistance with strong regeneration ability. It also presented resistance to cold, drought, saline and alkaline, and barren, with wide adaptability. Longh 1 was suitable for planting in mountains, plain field and irrigation area with frost-free period greater than 120 d, rainfall more than 250 mm, and altitude 1 500 -3 000 m. The application prospects of quinoa were also put forward in the paper.展开更多

Spraying 32 mg/L CPPU at 7 and 21 d post flowering for just once significantly improved the fruit size of mango, but had no significant impact on fruit quality and flavor. Spraying 200 mg/L ethychlozate at 7 d post flowering for just once significantly increased fruit drop rate and single fruit weight of mango; fruit grade was improved and total soluble solid increased to the maximum value, so ethychlozate had good fruit thinning effect.展开更多

It is an early-maturing variety with wide adaptability,high yield,and good commercial breeding. The plant has strong growth vigor and high resistance to white powder mildew. The first fruit sets on the 4 ^th-5^ th section,and the fruiting ratio of cucumber is 60%-80%. The cylindrical fruit is about 30-35 cm in length,3. 2-3. 5 cm in diameter with light green skin and glossy appearance. This plant has demonstrated adaptability in early-spring and late-autumn planting as well as spring and autumn tunnel planting.展开更多
