- Abstract
This research aims to screen out high-quality and high-yield rice varieties which are suitable for planting in Xinjiang region.【Methods】 The differences in growth and development, relative chlorophyll content (SPAD value), yield and quality traits of the sixteen tested rice varieties were comprehensively evaluated through varieties comparison and principal component analysis.【Results】 The whole growth period of the sixteen rice varieties ranged from 163 d to 173 d, the plant height showed an increasing trend as the growth processed, and the plant height reached the maximum at the full heading stage, ranging from 85.97 cm to 101.30 cm. The SPAD value showed an upward trend from the early tillering stage to the full heading stage, while the SPAD value significantly decreased from the full heading stage to the mature stage. There were differences among varieties, among which, Xinnongjingyi 4 had the longest filling stage, and the chlorophyll SPAD value was high, which was significantly better than that of other varieties. There was a correlation between the yield of each rice variety and the head rice rate, tasting value, milled rice rate and amylose content. Besides, principal component analysis showed that Xinnongjingyi 4 got the highest comprehensive score, followed by Xindao 36 and Xindao 57, and 09-57 scored the lowest.【Conclusion】 The quality and yield of Xinnongjingyi 4 are the best, followed by Xindao 36 and Xindao 57.
