Comparative Evaluation of Milling and Processing Quality Traits of Rice Varieties in Karakalpakstan
Abstract
The present study evaluates the technological quality indicators of rice samples selected from the breeding nursery under the agro-ecological conditions of Karakalpakstan. The research focused on key milling and processing characteristics, including husk content, grain translucency, bran yield, total milled rice yield, head rice recovery, and broken grain percentage. Comparative analysis was conducted against the local standard variety Sanam. The results revealed significant variability among the studied samples. In particular, some accessions demonstrated higher grain translucency (up to 31.7%), whereas head rice recovery ranged from 57.0% to 70.2%. At the same time, certain lines showed elevated bran yield and a higher proportion of broken grains, indicating comparatively lower technological quality. These findings highlight the importance of comprehensive evaluation of technological traits in rice breeding programs. The identified lines with favorable milling characteristics can serve as valuable genetic sources for developing high-quality rice varieties adapted to the stress-prone environments of Karakalpakstan.
