摘要:

为了推荐综合性状较优并能充分利用桂南光温资源的杂交稻品种,对9个感温型杂交籼稻新组合(含对照)进行完全随机区组小区试验,通过方差分析、排序比较,评鉴这些组合在桂南生态区晚季的特征特性。结果表明,‘深两优9353’、‘昌两优华占’、‘昌两优9号’、‘乾两优9号’、‘坤两优华占’、‘乾两优6号’产量、全生育期和抗性表现较适合桂南生态区。‘深两优9353’产量最高且显著高于对照组合;‘F优6735’和‘万泰香占’虽然抗性好,但是产量极显著或显著低于其他组合(含对照)。参试组合的产量与全生育期、总粒数、实粒数的相关性较好,而与其他性状相关性较差。6个感温型苗头组合利于充分利用桂南光温资源、发展冬种生产、调整产业结构,可作为桂南生态区早晚两季水稻生产备选组合。

Abstract:

To recommend hybrid rice varieties with better comprehensive traits and full utilization of light and temperature resources in southern Guangxi, 9 new Indica hybrid rice combinations (including controls) with temperature sensitivity were used in complete random block plot test, and the characteristics of these combinations in the late season in the ecological area of southern Guangxi were evaluated by variance analysis and sequencing comparison. The results showed that the yield, whole growth period and resistance of ‘Shenliangyou 9353’, ‘Changliangyou huazhan’, ‘Changliangyou 9’, ‘Qianliangyou 9’, ‘Kunliangyou huazhan’ and ‘Qianliangyou 6’ were suitable for the ecological area of southern Guangxi. The yield of ‘Shenliangyou 9353’ was the highest, which was significantly higher than that of the control. Although ‘Fyou 6735’ and ‘Wantai xiangzhan’ had good resistance, their yields were very significant or significantly lower than those of other combinations (including the control). The yield of the tested combinations correlated well with the whole growth period, the total grain number and real grain number, but not with other traits. Six temperature-sensitive seedling combinations can make full use of light and temperature resources in southern Guangxi ecological region, which are suitable for developing winter production and adjusting industrial structure, and can be used as alternative combinations in early and late rice production.
