| 摘 要： | 为明确杂交中籼水稻在江淮地区种植的适宜播期,提高稻米品质,选用3个杂交中籼水稻品种(系)分5个播期,利用AMMI模型对其营养食味品质性状(糊化温度、胶稠度、直链淀粉含量、蛋白质含量)进行了稳定性和适应性分析。结果表明,糊化温度、胶稠度、直链淀粉含量、蛋白质含量4项指标在基因型间、播期间及基因型×播期互作间的方差均达到极显著水平,这4项指标的交互效应主成分值(IPCA)差异也达到显著水平;穗期(抽穗至成熟期)平均气温较高、累计日照时数长、气温日较差大,有利于杂交中籼水稻品质的提高;3个参试品种(系)营养食味品质稳定性表现为新两优6号两优1128丰两优4号,5个播期对杂交中籼水稻品质影响表现为4月20日5月10日5月20日4月30日5月30日。

| 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. |
