“…A large number of hardwood families and genera possess the same haploid number and have evolved at diploid level (MEHRA, 1972;KREMER et al, 2007;OHRI and KHOSHOO, 1987;AHUJA, 1990, 1991;D'EMERICO et al, 1995;ZOLDOS et al, 1999;KUMAR and RAO, 2002;WANG et al, 2005;OUDJEHIH and BENTOUATI, 2006;CHOKCHAI -CHAMNANKIT et al, 2008;RIBEIRO et al, 2011;HYNNIEWTA et al, 2011;COULLERI et al, 2012). However, a large heterogeneity of somatic chromosome numbers is exemplified by Meliaceae with 2n=16, 20, 22, 24, 26, 28, 30, 32, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 72, 78, 80, 84, 92, 100, c150, c280, c360 (STYLE and VOSA, 1971;KHOSLA and STYLES, 1975).…”

How small and constrained is the genome size of angiosperm woody species

Angiosperm hardwood species are generally considered to show an average smaller genome size with a narrow range of variation than their herbaceous counterparts. Various explanations pertaining to limitations of cell size exerted by wood fibers, the requirement of smaller stomata, longer generation time, large population size, etc., have been put forward to account for their small and constrained genome size. Yet studies done in the past several years show that genomically as well as evolutionarily, hardwoods are as diverse and active as their herbaceous counterparts. This is entirely supported by the presence of well developed inter and intraspecific polyploid series and natural triploidy in many genera. Polyploidy, in some instances has been shown to confer adaptability to arid and salt stress conditions and in colonization of new areas. Moreover, hardwoods also show reasonable amenability to the induced polyploidy which abruptly changes the balance between nuclear and cell size. Polyploidy has been induced in many hardwoods to restore fertility in interspecific hybrids and for the production of triploids.Furthermore, some cases studied show that genome size variation in hardwoods can be as variable as that of herbaceous species. Genome size has been shown to vary remarkably both at homoploid level as well as by polyploidy in certain genera. In the same way, the genome size is not correlated with the habit in certain groups having both herbaceous and woody taxa. This point is further proved by the presence of secondary and insular woody habit in certain cases where either the transition to woodiness is not followed by any diminution in the genome size, or the genome size of insular woody species may be even more than that of the congeneric herbaceous species. This shows that woody habit does not by itself put any constraints on the genome size either at homoploid or at polyploidy levels. The genome size in fact, not only varies significantly in many congeneric woody species but also may not show any correlation with the habit when woody and herbaceous species are compared in some narrow taxonomic groups studied.

“…This species usually produces fruits twice a year, grows on various soil types at the altitude of 100-400 m above sea level (Dinesh and Reddy, 2012). From taxonomical point of view, C.maxima is considered to be one of three true Citrus species together with C. medica and C. reticulata based on karyotype analysis (Hynniewta et al, 2011). Its status as true or basic species within Citrus is confirmed by other researchers based on molecular analysis (Froelicher et al, 2011;Garcia-Lor et al, 2013).…”

Citrus maxima is a tropical fruit species with high morphological variability on fruit characters, including shape, size, thickness of peel, flesh color and taste. This variability has been used by breeders and common people to practically distinguish different pummelo cultivars. Despite such well known variation, so far there is no published study specifically addressed the extent of phenotypic variability and taxonomy of pummelo in Indonesia. This study was, therefore, aiming at assessing phenotypic variability and taxonomic affinity of Indonesian pummelo cultivars and landraces using multivariate analysis methods. A total of 60 accessions from six provinces were collected, including some representatives of registered cultivars. Twenty one morphological characters were subjected to cluster analysis and principal component analysis. Results showed that two major clusters were formed, in which each group was characterized by combination of distinctive morphological features leading to recognition of two cultivar groups. Based on the fact that the morphology of individuals from intensively cultivated orchards showed similar level of variability to those from sporadically distributed areas, there was strong indication that the morphological variation has genetic background.

“…Formula kariotipe Citrus sinensis adalah 16L+2V, tidak ada kromosom sub telosentrik dan telosentrik yang merupakan indikasi kestabilan genom serta tidak adanya perubahan struktural kromosom dalam genus Citrus. Sehingga, spesiasi dalam genus Citrus diduga disebabkan oleh mutasi gen yang tidak berpengaruh pada keseluruhan kromosom (Hynniewta et al, 2011).…”

Indonesia dikenal dengan kesuburan tanahnya. Berbagai jenis tanaman ditemukan di alam maupun dibudidayakan oleh masyarakat, salah satunya tanaman dari familia Rutaceae. Jumlah kromosom pada familia ini bervariasi yang menggambarkan karakteristik suatu genus. Modifikasi jumlah kromosom secara induksi arfisial mampu memproduksi spesies baru yang berpengaruh terhadap garis evolusi genus tersebut. Di sisi lian, variasi jumlah kromosom tersebut dapat dijadikan sebagai upaya perbaikan kualitas tanaman dalam rangka mengembangkan potensi dan produksi tanaman lokal.
