Summary Seasonal fluctuations in weather conditions were found to influence the flowering and fruiting phenology and reproductive biology of durian grown around Darwin. Manually assisted cross‐pollination resulted in higher fruit set of 31% in contrast to < 10% by selfing, producing higher yields and better quality fruit. Self‐pollination resulted in more fruit abortion and produced fruits that were mis‐shapen, curved with lower numbers of arils/locule, arils/fruit and lower numbers of seeds which were usually shrunken and disfunctional. Evidence from these studies also confirmed that the self‐incompatibility system in durian is gametophytically controlled and that cultivars could be totally self‐incompatible, partially self‐incompatible or totally compatible. The durian pollen was found to exert metaxenia effects that influenced the development of the fruit characteristics and also xenia effect on the seed.
