Embodiment 1
[0020] Example 1: Breeding HiZincR08-1 high-quality rice with high-zinc nutrition from various variety resources
[0021] Has collected and introduced 736 domestic and foreign rice variety resources. In Hangzhou in the summer of 2006, according to conventional methods of planting and management, 729 rice materials with normal firmness and full grains were selected and kept; the selected rice materials were selected, and an appropriate amount of seeds were reserved for future use. Refer to Levent Ozturk et al. (Concentration and localization of zinc during seed development and germination in wheat.Physiologia Plantarum, 2006, 128: 144-152) for primary screening of mature seeds by diphenylthiocarbazone staining. Before slicing, pre-soak for 1 hour, then slice vertically and horizontally, immerse in diphenylthiocarbazone solution for 30 minutes, rinse with water and blot dry with filter paper, then quickly place the sample on a glass slide, upward, and use a microscope Observed....
Embodiment 2
[0022] Example 2: High-zinc nutrition and high-quality rice "Lilizi" from mutagenic mutant plants
[0023] Using my country's high-quality late japonica rice ZF04-01 as material, after 250Gy cobalt-60 radiation mutagenesis treatment, the second generation of mutagenesis containing more than 20,000 plants was constructed in 2005. Hangzhou in the autumn of 2006, planted and managed according to conventional methods, planted 3000 of the second-generation mutant plants, and selected 2987 rice materials with normal firmness and full grains; take the above rice materials and keep appropriate amount of seeds for future use, refer to Levent Ozturk et al. (Concentration and localization of zinc during seed development and germination in wheat. Physiologia Plantarum, 2006, 128: 144-152) was used for primary screening of seeds by diphenylthiocarbazone staining. Before slicing, pre-soak for 1 hour, then slice longitudinally, immerse in diphenylthiocarbazone solution for 30 minutes, rinse ...
