摘要
针对有机大米产量明显低于普通大米的问题,本文论述了有机大米产业化与野生稻优异种质利用的关系,分析了野生稻优异基因利用现状、目前存在的问题以及解决问题的途径。提出在有机水稻品种选育过程中,通过利用野生稻优异基因,提高有机水稻品种抗病虫性、抗逆性(耐寒、耐旱、耐贫瘠)和光合效率等特性,从而推动野生稻优异种质利用,提高企业经济效益,解决化学物质残留和污染等问题。
The yield of organic rice production was singnificantly lower than that of common rice at present.The relationship between industrialization of organic rice and application of excellent wild rice germplasm was discused in this paper.The status quo of the use of wild rice excellent genes,the current problems and the methods to resolve the problems were also analyzed.Application of superior genes of wild rice could improve organic rice resistant to diseases and insect pests,resistance to cold,drought resistance,poor,and improve the photosynthetic efficiency in the process of organic rice breeding.
