Evaluation of rice lines obtained through in vitro anther culture for low water supply conditions
Main Article Content
Abstract
belonging to the National Institute of Agricultural Sciences
(INCA), 55 lines derived from in vitro anther culture of INCA
LP-10/C4 153 and Amistad-82/C4 153 crossings were evaluated
under field conditions, together with INCA LP-10, Amistad-82
and C4 153 parents, with drought-resistant genes, over 2001
spring. To induce low water supply conditions, the following
management was employed: the water lamina was established
15 days after rice germination (DDG), interrupting water entry
35 days DDG, recovering it again at the primordium change up
to 50 % flowering. These evaluations were performed: final
plant height (cm), panicles/plant, 100-grain-weight, full grains/
panicle, empty grains/panicle, grain length (10 out of them)
and yield/plant. Results showed a high response of F2
hybrids to anther culture, as well as and a phenotypical variability in the tested material related to their parents. The lines showing an appropriate performance were 19, 26, 27, 28, 43, 44, 47, 48 and 49, and the parent INCA LP-10.
