1999-2001 Qingyang new varieties of winter wheat (lines) Regional Trial
Seed planting sunflower area and the distance over the previous year should be at least 3km, to prevent bare raw sunflower seed oil sunflower} Kun and miscellaneous; 3km away from the area within the seed can not grow other sunflowers, and clear the area before flowering bare raw sunflower. Such as the use time of isolation, to grasp the sunflower planting sunflowers and other flowering stagger flowering more than 40d. 1.2 Seed Production Seed selection to choose flat terraces, with irrigated fields or square plots section, requiring good soil ripening, high fertility, avoid election cropping, cropping land, not with legumes or canola and other crops even stubble to prevent S. sclerotiorum infection. 1.3 Site Preparation moisture conservation, Shizujifei system requires intensive farming. After the autumn harvest time autumn plowing, deep plowing to 20 ~ 25cm appropriate; spring, according to the local climate, the soil has not thawed before (day midnight snack frozen) pay close attention to rake Mo repression; combination of soil preparation before sowing, application of quality manure 67.5 ~ 75.0t/hm, DAP 300kg/hm, urea 300kg/hm, potassium 150kg/hm (or ash l500 ~ 2500kg/hm), borax 7.5kg / Received date :2002-06-12; Amendment Date 2002-11-10 Author: Mao Xuhui (1972 a), male, Wudu, research interns, mainly engaged in special breeding and high-yielding oil crops cultivation techniques. Tel: (0931) 7614934. ��+-+--- Eleven - a - + a - a + a +---+ a --+-+-'- BU ten - + - 4 + A + A + - + A + A +-+-+ +-+-+ a +-+-- a 4 increase 4.48,4.04, yield significant variety �� location interaction effect of the variation coefficients were 7.94,12.61, variety �� year interaction effects are zero coefficient of variation, high stability coefficients were 23 .82,27.11 that Long 294 with high yield strong, stable and good, but 903412-2 yield stronger, on the sites with strong selective, and only suitable for eco-region in order to fulfill its potential yield. The remaining lines were cut than the main effects were lower than the control, high yield and poor. 2.3 Regional Comprehensive resistance testing integrated two-year points test species identification and field resistance (Table 2), the tested varieties (lines) 9192-4-1-2,90109 (13) a 1-2 -1,903412-1, Xifeng 2O (CK) in the drought resistance of 1 to 2 grade, cold tolerance is an anti-green dry, full grain, bulk density up to 799.2 ~ 827.7g / L; Longjian 294 ,903412-2, Longyuan 993, Beijing 8694 drought resistance of 2 to 4, cold resistance 1 to 2, anti-green dry 2 to 4. Summary 3.1 3 18 points two years (time) test results showed ,9192 -4-1-2 18 points (second) trial, 15 points (times) increase, an increase of 83.3 points,[link widoczny dla zalogowanych], drought tolerance Strong, high yield and good, should be in Xifeng, the town of the original, is - * a + - + A + A + - + Ning, county, Huachi, combined water and other counties (cities) in Sichuan plateau and plateau model; 90109 (13) a 1-12-1 in 18 points (second) trial, 13 points (times) increase, an increase of 72.2 points, my area of town in the original, combined water, Qingyang Xian, Central County demonstration of the North Central Region; 903412-1,903412-2 the cold, winter of prominent, drought resistance, high yield, good, desirable in the Central County, the town of the original, Huachi, Qingyang Xian and other positive demonstration of the North Central Region ; Long 294 with 18 (point) trial in 1l points (times) increase,[link widoczny dla zalogowanych], an increase of 61.1 points, drought, cold, lodging resistance, high yield,[link widoczny dla zalogowanych], strong,[link widoczny dla zalogowanych], should be in the positive rather,[link widoczny dla zalogowanych], the original town, county, combined water, demonstration and popularization Huachi counties; other lines due to poor yield or yield stability should not be popularized. 3.2 From the analysis results, the current regional test of the tested varieties (lines) in high yield, drought resistance have been more fully the performance test, the emergence of a number of drought resistance, high yield potential of new strains, such as the breeding Qingyang Teachers 9192-4-1-2 agricultural, forestry, Department of Qingyang Teachers breeding 90,109 (13) for a 1-2-1 and so on. However, due to stripe rust, powdery mildew from the red dwarf, yellow dwarf virus were not popular, so the promotion process in the model should be based on climatic conditions, pay attention to stripe rust and other major diseases surveillance and control to ensure high yield, stable yield.
