Abstract

Eating quality is of paramount importance to rice (Oryza sativa L.) consumers and soft rice with low amylose content has become popular in China. This study was conducted to evaluate the performance of soft rice grown in the early season (ES) dominated by non-soft rice. Field experiments were conducted in Yongan and Santang, Hunan Province, China from 2016-2018. Results showed that grain amylose content in soft rice cultivars was consistently lower in the ES compared to the late season (LS). The lower grain amylose content in the ES compared to the LS was partly attributed to higher average daily mean temperature during grain filling. No significant relationship was observed between grain yield and seed amylose content in ES rice. Soft rice cultivars produced a similar average grain yield to non-soft rice cultivars in the ES. These results encourage breeders to develop more ES rice cultivars with soft texture to meet the consumer demand for this type of rice.
