Abstract: Four new hybrid rice combinations were introduced into Lianjiang County in 2018, and a simple test of early rice combinations was conducted with the control Nongyou 90. The growth period, yield and adaptability of the tested combinations were investigated. The results showed that Yongyou 4949 had the highest yield of 509.5 kg per 667 m², which was 13.1% higher than Nongyou 90. It showed better comprehensive performance and higher yield potential, which could be further demonstrated and popularized.
