China is the first country to use heterosis successfully for commercial rice production. This study compared the main quality characteristics (head rice rate, chalky rice rate, chalkiness degree, gel consistency, amylose content, and length-to-width ratio) of 635 rice varieties (not including upland and glutinous rice) released from 2000 to 2014 to establish the quality status and offer suggest...
Grain quality currently represents a major problem in high yielding rice production in Iran and many other rice producing areas of the world. Quality assessment of rice involves the function of sensory tests and physicochemical determinations based on the chemical composition, cooking quality, gelatinization temperature and physical properties of cooked rice. These research genetic materials we...
Development of cultivars better adapted to drought stress in the arid and semi arid climatic conditions is considered as a major breeding objective. Grain quality is a trait with physico-chemical complexity depending primarily on genotype, is strongly affected by environmental factors and their interactions. Effect of terminal drought stress on quality traits of 18 triticale lines, comprising o...
Forty three rice genotypes were used to evaluate their aroma detection through sensory test. Aroma was detected by 1.7% KOH as a sensory test. Thirteen rice genotypes were detected having strong aroma; ten had moderate aroma; fifteen had slight aroma and five had no aroma. In case of grain shape study, 37 genotypes were evaluated as slender and six as medium. In this study, grain aroma had sign...
A computer simulation model was developed to determine the likely response of grain yield and quality of malting barley crops to differing availability of water or nitrogen (N) and differing soil and climatic conditions. The model was validated for New Zealand conditions by comparing the results of model simulations with data from malting barley crops grown in the Manawatu. Simulations were the...
The many factors that determine the price and suitability for processing of cereal grain can be divided into two groups: seasonal factors and inherited factors. Seasonal factors are largely determined by growing, harvesting, and storage conditions. These aspects of quality are readily tested and include moisture content, test weight, soundness of the grain, and the presence of contaminants. On ...
High-temperature stress degrades the grain quality of rice; nevertheless, the exogenous application of plant growth regulators (PGRs) might alleviate the negative effects of high temperatures. In the present study, we investigated the responses of rice grain quality to exogenously applied PGRs under high day temperatures (HDT) and high night temperatures (HNT) under controlled conditions. Four ...
