依試驗結果顯示檬果果型大小型歸納為三類，即大果種：果重在700公克以上，生育日數較長約150天以上，如‘金煌’、‘Keitta’；中果種：果重在250-350公克之間，生育期中等約130-140天之間，如‘Irwin’、‘White’、‘Nam Dok Mai’‘Pim Sen Man’等；小果種：果重在200公克以下，生育日數較短，在120天以下，如本地種、‘Dashehari’和‘Ruby’等。可見小果種成熟期比大果種成熟期有較早的趨勢。
Correlation studies among ten traits of mango (Mangifera indica L.) were estimated from ten mango cultivars. Most of the cultivars were all over six years old. Biostatistics was used to determine the correlation of each character among the cultivars in order to improve the efficiency of mango breeding as well as to reduce the breeding costs.
The fruit weight could be classified into three types: big-sized ones such as ‘Ching Hwang’ and ‘Keitt’ averagely weighed above 700g with a long fruit growth period over 150 days, medium-sized fruits such as ‘Irwin’, ‘white’, ‘Nam Dok Mai’, and ‘Pim Sen Man’ weighed from 250 to 350g with a fruit growth period of 130-140 days and small-sized fruits such as local variety, ‘Dashehari’, and ‘Ruby’ less than 200g with a fruits growth period of about 120 days. Small-sized cultivars tended to ripe earlier than big-sized cultivars.
The panicle colors, small flower color and fruit skin color associations were classified into three types. The first type was yellow-greenish panicle axil an yellow small-flower with a ripening yellow-green skin color. The second was pink panicle axil and whitish-yellow small-flower with a ripening yellow-green skin color. The last type was pink panicle axil and pink small flower with a ripening orange-red skin color.
Fruit setting number of each panicle was very low in big-sized culitvars while that of the small-sized cultivars was high up to eight fruits per panicle.
Correlation coefficient of different associated characteristics was above 0.868 for seed weight, leaf weigth, leaf area, panicle length and fruit weight among the cultivars. The percentage of pulp and fruit set number per panicle were very significantly negative correlated (-0.893). It was more than 0.833 for panicle length, leaf weight and leaf arca.
