2018年度晚造玉林市水稻品种区试结果评价

Evaluation of regional test results of rice varieties in Yulin City in 2018

【目的】对2018 年晚造玉林市水稻自有品种区试结果进行研究分析,为当地水稻自有品种产业发展提供技术支撑,为水稻自有品种审定提供科学依据。【方法】对参加国家水稻品种区域试验(玉林站)2 个组合试验的丰产性、适应性、抗逆性进行综合评价分析,筛选出适合玉林地区种植的高产、优质,高抗水稻新品种。【结果】参试品种全生育期之间差异明显,变幅在106 ~122d,最长的是丰顺优4 号,最短的是中菁优新华占;昌两优香3、丰田优101、丰顺优4 号、隆两优1212、昌两优丝苗、万泰香占、荣两优22、坤两优馥香占与对照比减产均达极显著水平;丰顺优1号与对照比增产达极显著水平;昌两优香2、丰田优103、昌两优9 号、丰田优999 增产没有达到显著水平;中菁优新华占、昌两优华占产量与对照相当。【结论】昌两优香2、丰田优103、昌两优华占、昌两优9 号、丰顺优1 号、丰田优999 在玉林地区种植的田间生长良好,生长势强,抗倒性强,抗逆性好,生育期与对照相当,产量和其他综合性状表现良好,符合玉林地区水稻选种目标。

【Objective】Study and analyze the results of regional trials of rice cultivars in Yulin City in the late 2018,to provide technical support for the development of local rice varieties industry,and to provide scientific basis for rice self-owned varieties examination and approval.【Method】Through comprehensive evaluation and analysis of the high yield,adaptability and stress resistance of two combined trials of the national rice variety regional trial (Yulin Station),the new high-yield,high-quality and high-resistant rice varieties suitable for planting in Yulin were selected. Provide scientific basis for variety certification.【Result 】There were obvious differences in the whole growth period of the tested varieties,with the variation range of 106-122d,the longest was Fengshunyou 4,the shortest was the Zhongqingyou Xinhua zhan;Changliangyou3,Fengtianyou 101,Fengshunyou 4,Longliangyou 1212,Changliangyou silk seedling,Wantai Xiangzhan,Rong Liangyou 22,Kun Liangyou Fuxiang proportion and control ratio reduced yield significantly, Fengshunyou 1 and control reached extremely significant level. The yield of Changliangyou Xiang 2,Toyota you 103,Changliangyou 9 and Toyota you 999 did not reach a significant level,while that of the Chinese elite was superior to Xinhua,and that of Changliangyou was equal to that of the control.【Conclusion 】“Changliangyouxiang2”,“ Fengtianyou103”“ Changliangyouhuazhan”,“ No. 9 Changliangyou”,“No. 1 Fengshunyou” and “Fengtianyou 999” planted in the Yulin area have good growth,strong growth potential and lodging resistance. Strong,good resistance,the growth period is comparable to the control,yield and other comprehensive traits are good,in line with the rice selection target in Yulin.
