More than half of the world’s population consumes rice as a staple food in their diet. Rice grain quality is receiving attention from both consumers and producers living standards rice-consuming regions has improved this emerged critical breeding target. Grain traits have strong influence on market value adoption new varieties by farmers. Consumer preferences for specific nutritional, physical,...

Rice grain yield and quality are two major foci of rice breeding. In this study, Chinese regional rice test data provide us the unique opportunity to analyze the relationship between yield and quality in rice, because China has an unusually wide range of rice cultivars. We analyzed the relationships between grain yield, yield components, and grain quality of 300 rice germplasms. Japonica was su...

Occurrence of chalkiness is a major problem as it is an important parameter in determining the quality of rice grains. High temperature during the grain filling period results in loose packing starch granules that could be due to the involvement of starch degrading enzymes i.e., amylases. Therefore, two rice genotypes viz., PAU 3699-13-2-1-1 and PR122 were sown at two different dates. Thirty-da...

As variations in kernel uniformity can affect rice milling performance, limited thickness-grading to remove thin kernels was evaluated for effects on milling yields. Along with unfractioned (UNF) rice of four long-grain cultivars, rough rice was mechanically sieved, resulting in two thickness fractions, Thick (>0.079 inch) and Thin (<0.079 inch). Milled rice yield (MRY) and head rice yield (HRY...

This paper proposes machine algorithm to grade (Premium, Grade A, Grade B and Grade C) the rice kernels using Multi-Class SVM. Maximum Variance method was applied to extract the rice kernels from background, then, after the chalk has been extracted from rice. The percentage of Head rice, broken rice and Brewers in rice samples were determined using ten geometric features. Multi-Class SVM classi...

In order to investigate the effect of OsAAP1 gene mutation on chalkiness traits rice endosperm and microstructure starch granules in endosperm, we used mutants as experimental materials, with help ordinary optical microscopes scanning electron microscopes, morphological structure arrangement Zhonghua 11 were observed controls. The results showed that rate, area degree significantly increased, s...
