摘要: 旨在探究水稻多基因型种群品种在不同生态稻区的适应性和稳定性,为多基因型种群品种的推广提供依据。选用参试品种‘尤群6号’、‘南八糯’和对照品种‘红优7号’开展田间试验,通过抗病性、农艺性状等指标进行综合评价。结果表明:参试品种‘尤群6号’(0.40~0.95 kg/m2)和‘南八糯’(0.81~1.04 kg/m2)在4个稻区产量显著高于对照品种(尤群6号在文山地区表现除外);田间发病总体较轻,个别品种在局部试验点表现有差异,‘尤群6号’在文山稻瘟病发生 (DI=48.66)和粳稻区楚雄稻曲病发生相对较重,仍需继续种植综合观察;品种生育期随试验点海拔的升高而缩短,株高随月平均气温升高而增高,品种内株高变异系数介于1.97~6.13之间。研究表明参试品种在籼粳混栽区红河表现最佳,籼稻区德宏表现较好,在文山、楚雄田间表现有待继续评价;总体上,表现出较好适应性和稳定性。

Abstract: The aim is to explore the adaptability and stability of multi-genotype varieties of rice in different ecological regions, to provide a basis for promotion of multi-genotype varieties. Rice Multi-genotype variety ''Youqun 6'', ''nanbanuo'' and control variety ''Hongyou 7'' were selected to conduct the field experiment. The comprehensive evaluation for tested varieties was carried out by means of disease resistance and agronomic traits. The results showed that the yield of ''Youqun 6'' (0.40 kg/m2-0.95 kg/m2) and ''Nanbanuo'' (0.81 kg/m2-1.04 kg/m2) were significant higher than the control variety (In addition to the performance of ''Youqun 6'' in ‘Wenshan’ area); The field disease occurred lighter overall, individual tested varieties showed differences in some test points, the rice blast of ''Youqun 6'' in ‘Wenshan’ (DI = 48.66) and the occurrence of rice false smut in the japonica rice area ‘chuxiong’ were relatively heavy and the varieties were still need to comprehensive observation for continuous years. The growth period of each variety was shortened with the elevation of the test site. The height of the plant was increased with the month average temperature. The coefficient variation of plant height within the rice varieties were between1.97-6.13. The results showed that the adaptation of the indica and japonica mixed area ‘Honghe’ performed best, indica area ‘Dehong’ performed well. The field performance in ‘Wenshan’ and ‘Chuxiong’ need further cultivation and comprehensive evaluation. On the whole, the adaptability and stability of tested varieties performed well.
