Seed is an essential input to sustain agricultural productivity. The expansion of agricultural areas to meet global food demand contributes to the emergence of pathogenic microorganisms that contaminate and infect crop seeds. Conventional technologies in controlling seed-borne diseases are, however, not environmentally sustainable. This inspired the authors to explore existing literature on organic disinfection techniques for crop production. Various integrated seed disinfection techniques for major food crops, including rice, wheat, barley, millet, buckwheat, and sorghum, have been presented in this study. Moreover, the authors explored the potentials of hot water treatment as an alternative treatment method in meeting the ideal seed quality for cultivation.

This study investigates the physicochemical properties and bioactive compounds of red pigmented rice (colored rice) by examining soaking and germination rates. As evaluated from the germination rate and sprout length of the germinating red rice, the optimal soaking condition was determined to be approximately 24 hours of soaking before germination. Increased germination time resulted in an increase in the L* and b* values and decreased a* value. Crude protein, crude fat, and crude ash contents in red rice were increased during germination, whereas the starch content was decreased. The α-amylase activity of red rice was higher than ordinary brown rice and showed rapid increase after 72 hours of germination, but β-amylase activity increased only slightly. The amounts of bioactive compounds, including γ-aminobutyric acid, total phenolics, and flavonoids in red rice, were increased during germination and were higher than values obtained in germinating ordinary brown rice.

The damage caused by typhoons to rice production has been increasing. To reduce this damage, wind-tolerant rice breeding programs have been conducted at the Yeongdeok substation (YS) of the National Institute of Crop Science (NICS). This study was conducted to examine the effects of these wind-tolerant rice breeding programs. Under the wind-tolerance screening facility (WTSF), the wind-tolerance of 17 rice varieties bred at NICS (usual rice) and 20 rice varieties bred at YS (wind-tolerant rice) were analyzed by evaluating six traits: white spikelet (WS), white panicle (WP), degree of wind damage (DG), ratio of ripened grain (RRG) at control (RRG_C) and treatment (RRG_T), and reduction rate of RRG between control and treatment (RRG_R). Wind-tolerant rice showed more wind-tolerant characteristics than usual rice, such as lower WS, WP, DG, and RRG_R and higher RRG_T and RRG_C. In the principal component analysis, wind-tolerant rice showing a similar direction for RRG_T and RRG_C were located separately from the usual rice. The adaptability tests of wind-tolerant rice were conducted by evaluating eight yield-related traits in the wind-prone areas. Wind-tolerant rice was divided into three clusters by K-means clustering analysis using WP and RRG_T with the WTSF, RRG, and yield in the wind-prone areas. Among the three clusters, YC2 had the strongest wind tolerance performance, followed by YC3 showing moderate wind tolerance, and YC1 the weakest wind tolerance. 'Sinbo', a variety belonging to YC2, exhibited the strongest wind tolerance and high yield potential among all varieties. The wind-tolerant rice varieties bred at YS could be used practically to prevent wind damage and utilize breeding materials to enhance the wind tolerance of rice varieties.
