优质高效粳稻品种在鄂西北地区的种植表现
|
摘要
从145份收集品种(系)中,初步筛选出了20个优质高效粳稻品种,研究和分析了它们在鄂西北地区种植的生育期、产量及其构成因素、外观米质和综合抗性。结果表明,甬优6763、甬优4949、甬优7053、甬优1526、甬优6760和南繁1605产量潜力大,综合表现好,可在鄂西北地区推广种植;扬育粳2号、宁5718、南繁1610、徐32646、盐粳16号、扬粳1612、皖垦粳3722产量表现相对较好,且无明显缺陷,需进一步考察这几个品种在鄂西北地区常年种植表现;华粳295和武运5020丰产性较好,但生育期较长,应适当提前播种;泗稻14-211和徐农33202产量较高,外观品质好,但纹枯病发生较重,抗倒伏能力一般,不宜在纹枯病发生较重地区种植;圣稻20、华粳8号和甬优2640具有一定的产量潜力,生育期适宜,但后期遭遇极端恶劣天气,出现少部分的倒伏现象,有待进一步试验示范。
Twenty japonica varieties with good quality and high efficiency were initially screened out among 145 collected varieties(lines),and their growth period, yield and components, rice quality and comprehensive resistance were studied and analyzed in the northwest of Hubei. The results indicated that Yongyou 6763,Yongyou 4949,Yongyou 7053,Yongyou 1526,Yongyou 6760 and Nanfan 1605 had good yield potential and good comprehensive performance, which could be cultivated in the northwest of Hubei. The yields of Yangyujing No.2,Ning 5718,Nanfan 1610,Xu 32646,Yanjing 16,Yangjing 1612 and Wankenjing 372 were relatively high,and there were not obvious defects, so it was necessary to investigate the annual performance of these varieties in the northwest of Hubei. Huajing 295 and Wuyun 5020 had good yields, but their growth period was too long, so the seeding time should be appropriate. Sidao 14-211 and Xunong 33202 had high yields and good appearance, but their banded sclerotial blight was severe and lodging resistance was general, so it was not suitable for planting in areas with serious banded sclerotial blight. Shengdao 20, Huajing 8 and Yongyou 2640 had certain yield potential, and their growth period was suitable, but they had defect on lodging in the extreme weather of the maturation stage, so further test and demonstration was needed.
