The changes of eating and cooking quality of indica early rice in different cropping seasons
Based on our early rice breeding practices in Hangzhou and in South China region, 14 varieties (or pure lines) with different apparent amylose content (AAC) were planted in early and late season in Hangzhou (30° N, HZE, HZL), Zhejiang province, East China, and winter season in Hainan province, South...

| Summary: | Based on our early rice breeding practices in Hangzhou and in South China region, 14 varieties (or pure lines) with different apparent amylose content (AAC) were planted in early and late season in Hangzhou (30° N, HZE, HZL), Zhejiang province, East China, and winter season in Hainan province, South China (18°N, HN), respectively. The changes in eating and cooking quality of each variety, including AAC, gelatination temperature (GT, akaline spreading value), gel consistency (GC) and RVA profiles were observed and scored. The results indicated that the values of AAC and GT were higher in HZL than in HZE, and those of HN were in between. Non-significant changes of GC and RVA profiles were observed among the three agroecological environments. It was suggested that GC and RVA profiles could be served as reference indicators for selecting the early rice with good quality. It seemed unnecessary to exert strict selection pressure upon the AAC and GT during the plant grown in different seasons. |
