Abstract : Breeding mango (Mangifera indica) cultivars and rootstocks in Israel is reviewed. Fifteen seedlings which produce fruits of high quality, good appearance, and covering the mango season in Israel from July to December, have been selected, and a table of their characteristics is presented. The selections Tango and Shelly are being tested on semi-commercial plots. Monoembryonic rootstocks tolerant of calcareous soils and saline irrigation water were selected. These were vegetatively propagated by rooting cuttings, and were grafted with commercial cultivars in order to evaluate their performance as rootstocks. Estimates for the genetic variance components were obtained through linear models and regression analysis between parents and progeny performance. The model worked best when the selfing level was estimated at 50%. In this analysis, the additive genetic variance was small and non-significant, and the non-additive component was large and significant for most traits. Estimates for genetic correlations between several traits were based on the performance of the parents and their progeny. The use of DNA fingerprinting and AFLP (amplified fragment length polymorphism) for cultivar identification is discussed.
