摘要
为筛选出适宜百色地区种植的优质高产水稻品种。选取“中浙优8号”“星火优201”“旱优78”和“野香优莉丝”4个水稻品种与对照品种“特优63”(CK)进行晚稻对比试验,分析其生育期、抗病性、抗倒伏性、田间植株表现、经济性状、产量及米质等。4个参试品种除“中浙优8号”生育期比对照品种“特优63”(CK)长之外,其他品种均比对照品种“特优63”(CK)短;各参试品种除了“中浙优8号”为重感纹枯病,其他品种对纹枯病、稻瘟病及抗倒伏等均表现较好抗性,总体抗性较好;“野香优莉丝”产量位居第一,达到524.8 kg/667 m^(2),效穗数最多,综合抗性好,米质优;“中浙优8号”产量位居第二,达到512.3 kg/667 m^(2),穗长最长,米质优;“星火优201”产量最低,仅为486.3 kg/667 m^(2),结实率最低,米质中等。在4个水稻参试品种中,“野香优莉丝”和“中浙优8号”综合性状表现优异,比较适宜在百色右江地区推广应用,其他品种可根据不同土壤和气候,结合品种特性推广种植。
In order to select high quality and high yielding rice varieties suitable for planting in the Baise area,four rice varieties,including"Zhongzheyou 8","Xinghuoyou 201","Hanyou 78",and"Yexiangyoulisi",were selected and compared with the control variety"Teyou 63"(CK)for the late rice experiment.The analysis focused on the growth period,disease resistance,lodging resistance,field plant performance,economic traits,yield,and rice quality were analyzed.Except for"Zhongzheyou 8",which had a longer growth period compared to the control variety"Teyou 63"(CK),all other varieties had shorter growth periods.Moreover,apart from“Zhongzheyou 8”,all the tested varieties showed good resistance to sheath wilt,rice blast and crouching,with overall good resistance.“YeXiangYoulisi”had the highest yield,reaching up to 524.8 kg/667 m^(2),the highest number of effective ears,good comprehensive resistance,and excellent rice quality.“ZhongzheYou 8”had the second highest yield,reaching up to 512.3 kg/667 m^(2),the longest ear length,and excellent rice quality.“Xinghuoyou 201”had the lowest yield,only 486.3 kg/667 m^(2),and the lowest seed setting rate,with medium rice quality.Among the 4 rice varieties tested,"YexiangYoulisi"and"Zhongzheyou 8"sexhibited good overall characteristics and were suitable for popularization and application in the Youjiang area of Baise.Other varieties could be popularized and planted based on different soil and climate conditions,in combination with variety characteristics.
