Abstract

Tetraploid citrus are important for interploidal hybridization to create triploid seedless citrus.  Colchicine is the most commonly used as antimitotic agent to induce polyploid plants.  Tetraploid induction by colchicine in Pummelo ‘Nambangan’ was conducted in vitro using different types of explants.  The aim of this research was to induce tetraploid pummelo ‘Nambangan’ by colchicine treatment using germinated seed, shoot tip and cotyledonary node as explants.  Tetraploid shoot induction was conducted by soaking germinated seeds, shoot tips and cotyledonary nodes in 0.1% colchicine for 1, 3 and 5 h.  Regenerant shoots were grown on MS medium and their growth was observed after four weeks in culture.  Ploidy level was determined using flow cytometry analysis.  Stomata density, length and width of stomatal guard cell were also recorded. The results showed that shoot elongation was inhibited by colchicine treatment.  Soaking of shoot tip explants in 0.1% colchicine for 1 h resulted in 66.66% of putative tetraploid shoots.  Compared to diploid shoots, tetraploids had lower stomata density but bigger in guard cell size. Keywords: colchicine, tetraploid, pummelo (Citrus maxima (Burm.)

Abstract

Breeding mangoes is a long term activity and complicated. One of difficulties is polyembryonic seeds. These factors make genetic improvement through conventional parental selection and breeding slow and unpredictable. Adoption of molecular markers and genomics-based breeding strategies will likely improve predictability and breeding efficiency. The objective of this study was to evaluate the occurrence of zygotic or nucellar in polyembryony mango cultivars Garifta Merah, Lalijiwo, Manalagi, Madu, Saigon Kuning, and Saigon Merah using RAPD and SSR markers. The type of embryo (zygotic or nucellar) was evaluated by comparing the exhibiting amplification patterns, if different from the mother plant considered as zygotic and identified as nucellar if they exhibited the same banding pattern as the mother plant. Out of the 16 SSR and 16 RAPD primers evaluated, 9 primers each amplified the largest number of allele and sharply defined band. Dendogram of the SSR primers divide into three groups while RAPD primers distinguish clearly into two major groups, zygotic group and nucellar group. Based on zygotic and nucellar size, number and position, indicating no relationship between the type of embryo and embryo size, number and the position.
