ANALISIS KERAGAAN FENOTIPE F1 HASIL PERSILANGAN JARAK PAGAR (Jatropha Curcas L.) SEBAGAI SUMBER BELAJAR GENETIKA PEWARISAN SIFAT
Abstrac: Physic nut (Jatropha
curcas L.) is a versatile plant and all parts of the body have the potential to
be exploited. Government has set as a source of biofuels (BBN) in supporting
the diversification of sources of alternative energy using the Physic nut.
Utilization target is 5 % of Indonesia's energy mix by 2025. Seethes need to be
supported in the future high yielding improved varieties. Problems faced are no
varieties or clones produced Physic nut. Hybridization is one method to obtain
high yielding varieties and has been done by breeders Physic nut. This study
was conducted to look at a number of phenotypic variability F1 crosses of
Physic nut in support of the data base of the hybrid varieties. The parameters
observed were plant height, number of branches, number of leaves indentations
and 100 seed weight. The results showed that the variability of phenotypes F1
hybridization of Physic nut plants vary in height, number of branches, 100 seed
weight and nearly uniform in curvature amount of leaves. 4 hybridization each
accession of parental: SP8 x SP16, F1 coded 5; SP8 x SP38, F1 coded 6; HS 49 x
SP33, F1 coded 7; SP38 x SM35, F1 coded 18, the results showed there are
differences and parent and offspring phenotype equations F1. F1 seed weight on
yield was higher than the parent. This process and result can be used as a
learning resource for studying the inheritance of the parent to the offspring
at genetic learning in secondary schools.
