A genetic barrier to outcrossing should be introduced into the herbicide-resistant crop to prevent the transferring of herbicide resistance to the weed species. It has become increasingly difficult to combat wild rice over the years as its morphological characteristic become closer to those of cultivated varieties because of strong selection pressuredue to long and careful weeding and possible natural hybridization with cultivated varieties. We examined correlations between plant functional traits, latitude, longitude and climatic variables in 34 populations of O. rufipogon across its northern range limit. Three lines (O. rufipopgon ILs) having O. rufipogon segment between RM242 and RM245 in common showed higher glossiness of cooked rice than Hwaseong and the other line (Hwaseong IL), indicating that Members of the genus grow as tall, wetland grasses, growing to 1–2 m tall; the genus includes both annual and perennial species.

UK: Crown Agents for Oversea Governments and Administrations. Rice cultivation in tropical Asia is susceptible to drought and flood and the need is high for stress resistant genes. Background Rice (Oryza sativa L.) is generally sensitive to low temperatures, and in production systems that use direct-seeding, low-temperature germinability (LTG) is a desired trait. This plant has no children Legal Status. Deka AK; Phookan AK, 1992. Thus, while considerable differentiation between founder Oryza rufipogon populations has been reported and further divergence has likely occurred since domestication, the common origin and inter-specific comparability suggests that the transcriptional regulation and genome structure is similar . in Yunnan, China.

Hand weeding is still practised, mainly in developing nations, but with hand weeding, workers are faced with the dilemma of distinguishing between weeds and the crop. Chemical control of O. rufipogon in rice is difficult because of the close genetic relationship between the weed and the crop. Since Ashina flowers 2-3 weeks earlier than Johra-dan, weeding of Johra-dan can be easily done after harvesting Ashina (Morishima et al., 1991).Salimath (1921) recommended rotating different rice cultivars with different coloured stems.
