Seeds are the “chips” of agriculture and the source of food. In recent years, japonica rice production in China has made great development in increasing grain production and increasing income and enriching grain rations. However, the current breeding level is still relatively lagging behind, mainly in the transition stage from 2.0 to 3.0, with long breeding cycle and low efficiency. The genetic diversity of germplasm resources is not enough and the genetic basis is relatively narrow. The problem of original technology being controlled by others is still widespread. Based on the thinking of various aspects of current japonica rice breeding and the main problems, the following breeding ideas were put forward in this paper: in-depth exploration of original functional genes, breakthrough of key core breeding techniques, creation of excellent new germplasm resources, development of major specific new varieties, in order to bring beneficial inspiration to the future japonica rice breeding work, help the revitalization of japonica rice industry, and stabilize the rice bowl in China.

Analysis on the Influence of Low Rice Price on Chinese Rice Industry ZHENG Hongming, ZHENG Pinhui 2023, 29(4): 32-37.  DOI: 10.3969/j.issn.1006-8082.2023.04.006 Abstract ( )   HTML ( )   PDF (705KB) ( )   In recent years, domestic and international food prices have fluctuated sharply and increased significantly due to the repeated COVID-19 pandemic, heightened geopolitical tensions and frequent climate disasters. However, the overall trend of the domestic rice market is stable, and the increase is not remarkable, which has become the veritable “ballast stone” of Chinese food security. Due to the stagflation of rice price, the ratio of rice price gradually ranks the bottom among the three main cereals, and the planting benefit is also at a low level among the three main cereals, which leads to the decrease of farmers' enthusiasm in planting rice and the gradual increase of the phenomenon of “water to drought”. All that mentioned above is expected to be difficult to change in the short term. Due to the low rice price, the substitution demand continues to increase, and the price difference between domestic and foreign rice also narrows significantly. Chinese rice imports are expected to decrease in the later stage, and domestic rice inventory reduction is accelerated. It is expected that the situation of the loose supply and demand of domestic rice market will change in the later stage. Therefore, it is necessary to take precautions and measures in advance to ensure that the rice bowl of the Chinese people is firmly in own hands.

It is of great significance to establish an accurate and efficient identification method for anaerobic germination tolerance and to screen rice germplasm resources with strong germinability under submerged condition for breeding new cultivars adapted to direct seeding. In this study, 20 rice varieties were used as the test materials, and the germinability under submerged condition was evaluated under different depths of waterlogging (3 cm, 6 cm, 9 cm, 12 cm, 15 cm and 18 cm), different temperature conditions (20 ℃, 25 ℃ and 30 ℃) and different days of waterlogging (3 d, 5 d, 7 d, 9 d, 11 d, 13 d and 15 d), and corresponding coleoptile length was deployed as an index for evaluating anaerobic tolerance at the germination stage. The results showed that the critical depth of flooding was 6 cm for japonica rice and 9 cm for indica rice, with a significant difference between the two subspecies. Under the condition of 30℃, the coleoptile length showed the highest interquartile range among varieties in the gradient temperature treatment. Therefore, it is considered that 30 ℃ is the optimum temperature for identification anaerobic tolerance at the germination stage. The gradient days of waterlogging treatment showed that coleoptile length shown the highest interquartile range after 11 days of waterlogging stress. Therefore, it is considered that 11 day after waterlogging treatment was the best time point to investigate germinability under submerged condition in rice. In summary, a simple and effective method for screening anaerobic germination tolerance was established, with pure water isolated from air at 30 ℃, more than 9 cm depth of waterlogging, and coleoptile length was measured at the 11th day of waterlogging, which provided a method basis for large-scale identification of rice germplasm resources with strong germinability under submerged condition. By taking use of the aforementioned pipeline, 140 germplasm resources released from different regions were screened, and 6 varieties with high anaerobic germination tolerance (coleoptile length≥55 mm) were found, which might provide a material basis for underlying the genetic mechanism and utilization in breeding program adapted to direct seeding.

Passivated Effect of Modified Rice Straw Biochar on Cd2+ in Paddy Soil and Rice Plant WEI Liangliang, LIU Shuodan, LI Min, WANG Ying, LI Yanduo, ZHAO Hongbo, Wang Nan 2023, 29(4): 72-77.  DOI: 10.3969/j.issn.1006-8082.2023.04.013 Abstract ( )   HTML ( )   PDF (1191KB) ( )   The passivated effect of rice straw biochar (BC) and its modified biochars impregnated with KMnO4, NaOH alkalization, hydroxyapatite impregnation and FeC13 impregnation modification methods on Cd2+ in paddy field soil and rice plant were studied by the method of acrylic casing, the dosage of 0, 0.3 and 0.6 kg/m2. The results showed that: 1) Without applying biochar, the content of available Cd2+ in paddy field soil could continue to accumulate with the rice growth period. Compared with the seedling stage, the available Cd2+ content in the soil decreased at the rice mature stage. When the dosage of biochar was 0.3 kg/m2, the available Cd2+ content in paddy field soil decreased the most under the BC-Mn treatment. At the dosage of biochar 0.6 kg/m2, the passivated effect of modified rice straw biochars on the available Cd2+ content was not as good as that of the original biochar. 2) After adding biochar, compared with the seedling stage, the total Cd2+ content in paddy field soil at the mature stage of rice decreased to varying degrees. Among them, the most significant effect was BC-Na treatment, and the total Cd2+ content decreased with the increase of BC-Na dosage. Compared with the rice seedling stage, the addition of biochar was beneficial to the improvement of soil organic matter content at the mature stage of rice. Among them, the effect of original biochar on soil organic matter content was significantly higher than that of the modified biochars. 3) The ability of each organ of the rice plant to enrich Cd2+ was in the following order: stem>leaf>grain. The application of BC-Na and BC-Fe in paddy soil could effectively reduce the content of Cd2+ in the rice grain, and which was better than BC, especially the BC-Fe treatment.
