江淮杂交中籼水稻品质性状基因型与播期互作的AMMI模型分析
Interaction of Genotypes with Sowing Dates for Main Quality Traits of Hybrid Mid-indica Rice in Jianghuai Region by AMMI Model
摘要
Abstract
In order to explore the suitable sowing datse and improve grain quality of rice, the genetic stability and adaptability of three rice culitivars with five different sowing dates were evaluated for nutritional and eating quality traits (gelatinization temperature, glue consistency, amylose content, protein content)based on AMMI model. The results showed that the differences in nutritional and eating quality traits among genotypes, sowing date and genotype×sowing date interactions were all significant at 1％level. Gelatinization tem-perature, glue consistency, amylose content, protein content were also significantly different in IPCA value. The environment factors of different sowing date with high mean temperature, enough accumulated sunshine hours and large diurnal temperature range from rice heading stage to maturity stage were beneficial to produce good quality of hybrid mid-indica rice. The order of stability of nutritional and eating quality traits for the 3 cultivars was: Xinlianyou 6>Liangyou 1128>Fengliangyou 4. The order for identifying rice quality of five sowing date was:April 20th>May 10th>May 20th>April 30th>May 30th.关键词
