ABSTRACT
In Bangladesh conditions, the end of the Boro season begins floods and natural calamities and loses more rice in farmer's fields. If we can select early maturity genotypes for the Boro season, we can harvest our rice from the farmer's field before flooding or any other natural calamities. The study attempted to determine the short duration and high yielding rice genotype for Boro season in Bangladesh amongst the 13 Boro rice F6 lines by contrast with two (2) test varieties. Keeping in view this idea, the output of the genotypes studied, the relationship between different morpho-physio-chemical and yield-contributing characteristics between all the genotypes were investigated there under field and laboratory conditions. Among these 15 lines, G11 line showed better in the most yield contributing parameters. It is therefore concluded that the G11 genotype will be considered an appropriate line for the Boro season in Bangladesh.
