Abstract In the changing climatic scenario, application of proteomics for accelerated identification elite genes is an important way to speed up development lines. Seeds, reservoir protein expression in most aspects plant development, are attractive platform identifying unique/novel proteins. There has been no report on seed proteome basmati rice ( Oryza sativa L.). This study presents, first time, superior Indian varieties Pusa Basmati 1121 and 1718, which genetic resources breeding. Through label‐free quantitative proteomics, a new source was identified by exploiting predominant abundance unique peptides. The hub related flowering time revealed probable photoperiod‐independent pathway with abundant Photoperiod Independent Flowering Gene 1 protein. 1718 contained proteins ABA synthesis biotic abiotic tolerance, respectively. signature peptides thaumatin‐like antimicrobial from addition rice. primary structure analysis indicated lysine status, while non‐starch glucans sent clues targeted research these as therapeutic food.
