Rice (Oryza sativa) is an important food crop and has two subspecies, indica and japonica. Since the last century, four generations of rice varieties have been applied to rice production. Semi-dwarf rice, intra-subspecific hybrid rice, and inter-subspecific introgression rice were developed successively by genetic modification based on the first generation of tall rice. Each generation of rice has greater yield potential than the previous generation. Due to the stronger heterosis of indica-japonica hybrids, utilization of the inter-subspecific heterosis has long been of interest. However, indi...

Increased and more stable rice yields contribute to food security while also allowing small-scale farmers to diversify their crop system. SRI rice panicles have fewer unfilled or broken grains which increases the amount of milled rice from harvested paddy by up to 15%. SRI methods also increase the micronutrient uptake by the plant, resulting in improved nutritional qualities in the grain. Beneficial nutrients such as Iron, Zinc, Copper and Manganese are all found to increase in SRI rice when compared with traditionally cultivated rice. Levels of heavy metals, such as arsenic and lead, are sho...
