VARIATION IN MORPHOLOGY OF JUJUBE ‘MUZAO’ (ZIZIPHUS JUJUBA MILL.) IN THE LOSSES PLATEAU OF CHINA

The morphological variations of the 29 clones of ‘Muzao’ (Ziziphus jujuba Mill.) were studied in the present study.
The results showed that there were significant differences among morphological variations of the shoots, leaves, fruits and stones.
The largest variation was found in the shoots, followed by the leaves, fruits, and stones.
In the shoots, variation of primary extension shoot was the biggest, while that of bearing shoot was the least.
In the leaf traits, leaf index showed least variation.
But in the fruit traits, variation of fruit mass was the largest while that of edible rate was the least.
There were great variations in dried rate, total sugar and soluble acid content among fruits of the clones.
In the traits of fruit-stones, variation of stone mass was the largest, while variation of stone index was the least.
Using the 12 traits for clustering analysis, we found that 29 clones can be divided into four groups based on genetic distance of 8.5. These data could be used as important parameters for the selection of high quality clones or cultivars in ‘Muzao’.
