Abstracts
A set of 21 maize inbreds were evaluated for 29 traits for studying the Distinctness, Uniformity and Stability parameters as per the guidelines issued by the Protection of Plant Varieties and Farmers Rights Authority (PPV&FRA), India. Out of 29 traits, five traits were monomorphic, 18 traits were dimorphic, while six traits were polymorphic. The studied quantitative traits were independent and their interaction with environment as well as themselves were negligible as revealed by modified joint regression analysis. The combine over year analysis revealed that five inbreds were completely uniform, for all the MS or MG traits, while rest of the inbreds were non-uniform for 1–4 traits, but within the acceptable limit of uniformity test as per PPV&FRA guideline. Combine over year distinct analysis revealed that all the studied inbreds were found distinct to each other except VQL 1 and CM 212, which showed non-distinctiveness to each other but showed distinctiveness to other 19 inbreds. The present data can be used to develop database for inbreds and also safeguard the ownership issue.
