摘　　要：应用前人的基因型×环境互作的加性、显性遗传模型(ADE),在盐胁迫条件下,对水稻稻米外观品质性状进行遗传效应分析,结果表明:①水稻稻米的外观品质性状普遍存在基因加性效应和显性效应,以及基因型×环境互作效应.但不同性状的加性效应和显性效应所起的作用有所不同;②不同性状的遗传率大小不同,所受环境的影响也不同.外观品质性状的遗传率都以普通狭义遗传率为主,互作狭义遗传率较小;③谷粒长、谷粒宽、糙米宽、糙米长、糙米厚和糙米率等性状在盐胁迫条件下,有比较稳定的遗传表现.The homozygous male-sterile-line of rapeseed （Brassica napus L. ） 1178AB was crossed with 6 different vegetable varieties of Cruciferae and the effective seed-setting and compatibility index of the Fls were analyzed so as to understand the compatibility of distant hybridization between 1178AB and other species of Cruciferae. Remarkable differences were noticed in different cross combinations in their cross compatibility. Cross compatibility was the strongest in the cross of 1178AB x B. campestris ssp. chinensis ver. Purpured Hort and the poorest in the cross of 1178AB x B. campestris ssp.
