【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 determine the suitable sowing date of medium indica hybrid rice in Jianghuai area and improve rice quality, three medium indica hybrid rice varieties (lines) were selected for 5 sowing periods. The nutritional and edible quality traits (gelatinization temperature and gel consistency) were analyzed by AMMI model. The stability and adaptability of amylose content and protein content were analyzed. The results showed that the gelatinization temperature, gel consistency, amylose content and protein content were among genotypes. The variance between sowing period and genotype 脳 sowing date interaction reached extremely significant level, and the difference of interaction principal component value (IPCA) of these four indexes also reached significant level, the average temperature at panicle stage (heading to maturity) was higher, and the accumulated sunshine hours were long. The daily temperature range is large, It is beneficial to improve the quality of hybrid medium indica rice, and the stability of nutritive taste quality of three varieties (lines) is as follows: Xinliangyou 6, Liangyou 1128, Fengliangyou 4, and the effect of 5 sowing dates on the quality of hybrid medium indica rice on April 20. May 10, May 20, April 30, May 30.
