Bloom data of eight mume cultivars was investigated in the middle part of Taiwan. Date of start bloom occurred from the end of December till middle of January. The full bloom period began in early January to middle February. Season of available maturity for picking started from the end of March and finished at early of May. Fruit setting percentage of mume cultiavars under natural open pollination was varied from 29.2 % to 56.9%.
Mume fruit involving 27 measurable and unmeasured characters were detected and described in the experiment. Biostatistics was used to determine the difference between leaf character and fruit character among the eight cultivars. The results indicated that leaf weight, leaf area, leaf width, fruit weight, seed weight, fruit height and fruit width were very significantly different among the cultivars.
The test of correlation coefficient between leaf weight and leaf area was estimated to be 0.94. The correlation coefficients among leaf weight, fruit weight and seed weight were 0.80 and 0.72 respectively. These results revealed if a mume plant its leaf weight more than 0.47g may gain a fruit more than 20g. Apply this result to the early stage of seedling selection may increase the possibility of fruit breeding to obtain the larger fruit of new mume cultivar.
