Rice improvement program for swampland areas is mainly addressed to develop high
yielding varieties with the desirable agronomic characteristics along with the improved
adaptability to all growth limiting factors inherent in the ecosystem. This study was
implemented to evaluate the growth and yield performances of 10 rice F3 populations
generated from the crosses involving Bengkulu swamp rice landraces (Hanafi Putih,
Batubara, Harum Curup, Tigo-tigo, and Lubuk Durian) and the cultivated varieties
(Diah Suci, Bestari, and Sidenuk) on a swampland. The experiment was laid out on a
shallow inland swamp with stagnant inundation up to 50 cm depth during the plant
growth period. Data were collected for plant height, tiller number, number of
productive tillers clump-1, heading date, maturity date, panicle length, number of grain
panicle-1, 100-grain weight, and grain yield clump-1. High variability among the
populations was observed for most of the traits and readily explored for the
development of rice varieties well adapted to swampland. The principal component
analysis showed that the populations were distinguishable on the basis of the observed
traits. The magnitude of broad sense heritability and genetic advance estimates denoted
that simple phenotypic selection should be sufficient for gaining genetic improvement
for the majority of the traits, excluding panicle length.
