The results were as follows: Firstly, the S-locus of Katy was heterozygous, and self-compatibility was dominant to self-incompatibility. Secondly, a very extensive segregation in self-pollinated fruiting rate, fertile flower rate and average fruit weight was observed in the F1 populations, and averages of these traits were lower than that of mid-parent means. Therefore, these traits were confirmed to be quantitative.
结果表明,(1)凯特杏的S基因位点为杂合型,自交亲和对自交不亲和为显性遗传;(2)3个杂交组合的自交坐果率、有效花比率及平均单果重等性状在F1中广泛分离,杂种群体的平均值低于亲中值,表现明显的衰退现象,表明这3个性状均为数量性状。

Second, wetland landscape pattern dynamic change of Kenli County Take TM as the information source, according to studies the region wetland ecosystem present situation characteristic, wetland is divided into 10 kinds: irrigation paddy field, pit pond water surface, cultivation water surface, artificial ditch, reservoir water surface, salt field, rivers water surface, reed, shallow seas and tidelands, beach. The wetland landscape area is remarkable dropt from 1987 to 2004.In 1987 the wetland area occupied 14.10% of Kenli county, but only was 12.33% in 2004, it reduced 6155.12 hm2 in 17 years and average reduced 362.07 hm2 every year, the reduction scope of shallow seas and tidelands wetland is biggest 3894.78 hm2. The shallow seas and tidelands and reed are frequent transformation with other type.
