Abstract:

Understanding agronomic and physiological characteristics of green super rice (GSR) is essential to make strategies for breeding GSR varieties and crop management. This study aimed to identify major agronomic and physiological traits associated with high grain yield and high nitrogen use efficiency (NUE) of rice. Four GSR varieties and two control varieties (one super rice variety and one non-super rice inbred) were grown in the paddy field. The results showed that the GSR varieties produced higher grain yield and higher NUE than control varieties. Synchronous increases in both total spikelet number and filled-grain percentage contributed to higher grain yield, and an increase in grain yield production per unit absorbed N (internal NUE) resulted in higher NUE for GSR. Compared with control varieties, GSR varieties exhibited greater percentage of productive tillers and the ratio of spikelet number to leaf area, higher ratio of sugar amount to spikelet number at the heading time, higher crop growth rate, net assimilate rate, and root oxidation activity and more remobilization of assimilates from stems and sheaths to grains during the grain filling period, and higher harvest index at maturity. These traits were positively and very significantly correlated with both grain yield and internal NUE, and could be used as indexes for breeding and selecting GSR varieties.

Key words: green super rice (GSR), grain yield, internal nitrogen use efficiency, population quality, physiological trait
