以籼粳杂交后代选育出稳定的13个偏粳型恢复系R1～R13;14个偏籼型恢复系R14～R27作为试验材料,系统分析了株高、穗长、粒长、穗总粒数、穗实粒数、结实率、有效穗、千粒重8个农艺性状在昆明、玉溪、弥勒、开远4个不同环境下的表现以及相关分析。结果表明:恢复系主要农艺性状的变化主要是海拔高度差异造成的;株高、粒长、穗长随海拔的降低而增大;在不同海拔条件下株高、粒长、穗长、千粒重相对而言易受环境影响,其次是穗总粒数、穗实粒数、结实率,而有效穗相对比较稳定,受环境影响较小。
The stable japonica restorer lines R1 ~ R13 and the indica restorer lines R14 ~ R27 were bred in the progeny of indica-japonica hybrids as test materials. The characters of plant height, spike length, grain length, Number of spike grains, seed setting rate, effective panicle, eight thousand agronomic traits in Kunming, Yuxi, Maitreya, Kaiyuan performance under four different environments and related analysis. The results showed that the main agronomic traits in the restorer were mainly caused by the difference in altitude. The height, grain length and ear length increased with the altitude decreasing. The plant height, grain length, spike length and 1000-grain weight at different altitude In terms of environmental susceptibility, followed by the total grain number of spikes, grain number per spike, seed setting rate, while the effective spike is relatively stable, less affected by the environment.
