Description
The main objectives of this study are to determine the cytological behaviour and yield
component relations of F1 hybrid between Oryza sativa L. Ayaramin cv. and days (90). As
living condition are being improved human demand for high quality rice is continuously on
increase, which entailed in incorporation of preferred grain quality features as the most
important objective next to yield enhancement. The study was conducted at Botany
Department, Yadanabon University. Oryza sativa L. Ayarmin cv. ♂ × days (90) ♀ were used
for hybridization efficiency of crossing methods. This method involves emasculation by anther
aspiration suitable to this variety. The emasculation of anther aspiration achieved significantly
more seed set was obtained from F1 hybrid plants. Pollen fertility was determined from more
than 1000 pollen grains from parents and F1 hybrids. The pollen grains were stained in 1%. I2
KI solution. Pollen fertility of hybrid was 94.10%. The interspecific hybrid of Oryza sativa L.
of yield component were significant for all characters in F1 generation except number of plant
height. Although meiotic abnormalities showed significant association with pollen fertilites
more than 90% of the PMCs of the hybrids showed normal meiosis cell division. The yield
related to traits such as plant height, days to heading, days to maturity length, tiller per plant,
grains per panicle 1000 grains weight were analysis and compared with student 't' test.
