籼粳杂交后代稻米的耐贮性分析
Analysis of Storage Capacity of Indica-japonica Hybrid Progeny Rice
摘要
Abstract
10 different types of hybrid combinations were selected,and the dynamic change indexes such as germination rate,germination potential,malondialdehyde content and electrical conductivity of rice were detected every 90 d after artificial rapid aging.The results showed that the germination rate and germination potential of all varieties decreased with the extension of storage time.The electrical conductivity of Zheyou 21 increased the fastest while that of other varieties increased steadily.In rice storage,except in the early stage of storage,the electri-cal conductivity values were highly correlated with the germination rate,the electrical conductivity values and the germination potential,and the germination rate and the germination potential were highly correlated,and the correlation coefficients ranged from-0.85∗∗～-0.96∗∗,-0.85∗∗～-0.94∗∗,and 0.95∗∗～1.00∗∗,respectively.These results indicated that the above traits were the common genetic basis and could reflect the different storage characteristics among varieties.There were obvious differences in the storability of different varieties.Accord-ing to the estimation results of membership function and comprehensive evaluation,the storability of different varieties was J1s/Yuhe>J1s/F137>Zhongzheyou 8>61s/Yühe>LuS/Yühe>LuS/Zhenmei>Huchuang S/Zhenmei>61s/C84>Yongyou 1540>Zheyou 21.关键词
