Maternal and Paternal Effect on the Characters of Durian (Durio Zibethinus Murr.) Fruit from Cross-Pollination

The aim of the research was to study the influence of maternal and paternal parents on the characters of durian fruit resulted from their crossing. The parents used in the crossings were Matahari, Kani, Otong, Sitokong, Lai, Kim, Sunan, Bokor, Hortimart and Tangkue. The results showed that the percentage of fruit set of their crossing ranged between 0% and 20%. Maternal effect was significant on the characters of fruit set, fruit weight, fruit circumference, fruit length, fruit rind thickness, flesh thickness, edible portion, spine length, the number of locules without the pulp, seed weight per fruit, seed number per fruit, and percentage of deflated seed. The use of Matahari variety as maternal parent produced the largest fruit with the thickest flesh, the highest percentage of edible portion and all locules were filled. Paternal effect occurs on fruit set, fruit length, rind thickness, seed number per fruit, seed weight per fruit, and percentage of deflated seed. The use of Sitokong variety as paternal parent resulted the lowest seed weight per fruit, seeds number per fruit and the highest percentage of deflated seed.
