| 中文摘要 | The development of rice allelopathy is to lessen reliance oil herbicides and reduce tabour input ill paddy ecosystems. The varietal improvement in rice allelopathy is all essential prerequisite for the practical application of paddy weed control. In this Study, allelopathic rice PI312777 was hybridized with non-allelopathic modern rice cultivars N28S, N9S, N2S, N13S, Peiai64S and Tehuazhan35 in South China. weed suppression and allelopathic index of these seven parents and their progeny plants were investigated in field and laboratory. Crosses between allelopathic and non-allelopathic rice varieties showed that allelopathic traits are quantitatively inherited and inheritance pattern of allelopathy in rice showed polymorphism in allelic interactions. particularly. allelopathic traits of N2S/PI312777 progeny plants were enhanced,really and there was positively-significant heterotic effect between allelopathic PI312777 and non-allelopathic N2S. Three rice lines of high grain yields and potent weed suppression in 17 derived from the crosses among those of N2S and PI312777 were selected as candidates for commercially acceptable allelopathic rice cultivars. These three allelopathic rice lines greatly reduced the emergence and growth of paddy weeds, besides no grain yield reduction Occurred than control. Allelopathic rice No 1, a commercially acceptable allelopathic rice cultivar, is developing in Guangdong Province, China. |
