龙岩市优质杂交中稻新品种筛选与综合评价

Screening and Comprehensive Evaluation of the New Hybrid Rice Varieties with High Quality in Longyan City

为了筛选出适合在龙岩市新罗区种植的优质杂交中稻品种,2023年选用6个优质杂交水稻新品种,以荟丰优3301为对照进行对比试验,综合分析了各参试水稻品种的产量、生育期、主要农艺性状、植株生长性状、田间抗性等方面,结果表明:野香优699实割产量9622.5 kg·hm^(−2),比对照荟丰优3301增产15.6%,抗性较好;泰两优217实割产量8712.0 kg·hm^(−2),比对照荟丰优3301增产4.69%,抗性较好;荃优967实割产量8259.0 kg·hm^(−2),与对照产量相当,但抗性较好。以上3个品种建议继续扩大示范面积,进一步观察各品种农艺性状、适应能力、抗逆性等。泰丰优208、臻两优钰占、隆望两优889等3个品种产量不及对照,且抗病能力较弱、生育期短、成熟期早,不建议在新罗区作中稻和烟后稻推广种植。

In order to screen out the high-quality hybrid rice varieties which were suitable for being planted in Xinluo District of Longyan City,six new varieties of hybrid rice with high quality were selected to carry out the comparative test with Huifengyou 3301 as the control group in 2023.Then,the yield,growth period,main agronomic traits,plant growth traits and field resistance of each tested variety were comprehensively analyzed.The results showed that the real-cutting yield of Yexiangyou 699 was 9622.5 kg·hm^(-2),which was 15.6%higher than that of Huifengyou 3301,and the resistance was better.The real-cutting yield of Tailiangyou 217 was 8712.0 kg·hm^(-2),which was 4.69%higher than that of the control group Huifengyou 3301,and the resistance was better.The real-cutting yield of Quanyou 967 was 8259.0 kg·hm^(-2),which was equivalent to that of the control group,but the resistance was better.These three varieties were recommended to continue to expand the demonstration area,thus to further observe the agronomic traits,adaptability,and stress resistance of each variety.The yield of the three varieties,such as Taifengyou 208,Zhenliangyou Yuzhan and Longwang Liangyou 889,was lower than that of the control group,and the disease resistance was weak,the growth period was short,and the maturation period was early.Therefore,they were not recommended to be planted as the middleseason rice and post-tobacco rice in Xinluo District.
