GROWTH AND GENETIC CHARACTERISTICS OF CUCUMBER (CUCUMIS SATIVUS L.) CULTIVAR MERCY F1 HYBRID AND MUTANT POPULATIONS

Phenotypic and genotypic diversity is essential needs more enhancement in different ways to achieve higher productivity better quality vegetables. The presented research aimed study the phenotypic characteristics determine genetic of F1 populations compared with colchicine mutant variants Mercy cultivar cucumber (Cucumis sativus L.), held from March May 2019 at experimental field Department Agrotechnology, Islamic University Riau, Pekanbaru, Indonesia. A total number 144 studied plants comprised 72 each two plant groups. data recorded on various parameters attained statistical analysis using paired T-test a significant P < 0.05. Comparisons between both groups included karyotypes chromosome shapes, idiograms, sequencing. results revealed that, average, taller came (93.49 cm), followed by mutants same (67.83 cm). hybrids showed early flowering (29.00 days) colchicine-treated (33.31 days). However, fruits fruit weight were (9.39 1055.39 g), populations. have chromosomes, especially arm size. An idiogram also exhibited differences length groups, while primers trnL-F trnL-R target sequences DNA sequence length. Using seeds demonstrates change character increase production. polyploidy did not occur, alterations measured arms. As result, future increased concentrations imperative obtain chromosomal mutations.
