摘要
2019-2020年度春小麦品种比较试验在西藏自治区农业研究所4号试验地进行,通过对参试品种(系)在田间的长势长相进行观察鉴定,客观地评价了春小麦在各个时期的表现,并结合室内考种进行比较分析,选育出丰产、稳产、优质、抗逆性强、适应性广的品种(系),为生产、科研奠定基础。结果表明:通过两年的试验13个参试品种(系)(含对照)产量水平在378.18~545.62 kg/667 m^(2)之间,参试品种(系)产量均高于对照“山春1号”,较对照增产1.3%~44.3%,参试品种(系)产量均低于自设对照“藏春951”。根据综合评价,筛选出较好的3个小麦新品种(系)N16-3583、16-3659、16-3355,推荐到下一轮的全区区域试验。
The varieties comparative test of spring wheat in 2019-2020 was carried out at the 4th experimental site of the Agricultural Research Institute of Tibet Autonomous Region.Through the observation and identification of the growth and appearance of the tested varieties(lines)in the field,objectively evaluate the performance of spring wheat in various periods.Combined with the indoor test,the comparative analysis were carried out,and the new varieties(lines)with high and stable yield,high quality,strong resistance to stress,wide adaptability were bred,which laid the foundation for production and scientific research.The two-year test results show that,the yield level of 13 tested varieties(lines)(including controls)was between 378.18 kg/667 m^(2) and 545.62 kg/667 m^(2);The yield of tested varieties(lines)was higher than that of control“Shanchun 1”,and the yield increased by 0.05%~1.3%compared than the control;The yield of tested varieties(lines)was lower than that of self-designed control“Tibetan spring 951”.Based on the comprehensive evaluation,A better selection of 3 new wheat varieties(lines):N16-3583、16-3659、16-3355 were screen out and recommended to the next round of regional tests.
