摘要
根据对2003—2008年漳州市水稻品种区域试验资料的分析表明,三系杂交稻是漳州市水稻区试品种的主要类型,而特优组合又占三系杂交稻的多数;漳州市水稻新品种选育,2008年与2003年相比较,平均产量水平极显著增加,稻米外观品质普遍表现较好,但整体抗性无明显提高。适当增加植株高度对产量的提高具有重要的间接促进作用,在保持适当的穗粒数、有效穗数的前提下,千粒重和结实率的提高对产量的提高具有重要的作用。并提出进一步提高育种水平的建议。
The data of Zhangzhou rice regional trial from the year 2003 to 2008 were analyzed.The results indicated that three-line hybrid rice was the main type in Zhangzhou rice regional trial,and Teyou combinations were the most varieties of that;in improvement of indica rice varieties in Zhangzhou,the average yield of 2008 increased very significantly than that of 2003,grain appearance quality was improved significantly,but resistance to main pests was not improved obviously compared to that in 2003.Proper heightening plant would play an important role indirectly to increase yield.Based on suitable number of effective panicle and grains per panicle,it was very important to increace 1000-grain weight and seed setting rate to improve the yield.strategies were proposed for raising the breeding level further.
