Abstract:
Doubled haploid technique offers prominent opportunities in achieving homozygosis within a short period of time. The present investigation focussed on advancement of anther derived promising Doubled Haploids to assess the yield and yield associated characters namely days to 50 % flowering, plant height, panicle length and grain yield. Analysis of variance showed notable variations among the DHs with regard to all the studied attributes. There is a significant variation observed between the correlation coefficient of genotyping and phenotyping analysis. Among all the studied traits, a significant positive correlation was recorded between days to 50 % flowering and grain yield. This study showed a strong correlation among all the yield related traits of the DHs. The DHs possessing the promising yield traits could be utilized in breeding programme for increase the rice productivity.
