Abstrakt:	Egyptian clover/Berseem ( Trifolium alexandrinum L.) is the most popular winter leguminous multi-cut fodder crop widely cultivated in the northwest and central parts of India. Quality seed significantly impacts farm productivity, farmers' profitability, and socioeconomic welfare. Foundation and certified seeds enable high-quality seed production, making breeder seed (BS) the most important link in the seed supply chain. In India, berseem BS indent had increased from 1998 - 99 to 2012-13; afterwards, it followed a constant but decreasing trend. Of the 27 notified cultivars, 24 came into the seed supply chain between 1998-1999 and 2021-2022, indicating high varietal availability to stakeholders. The study examines the potential causes of the national decline in BS indent and production and the differences in these figures over time. The highest BS indent was received for the variety JB-1 (276.1 q), followed by BL-10 (205.1 q), Mescavi (165.6 q) and Wardan (153.7 q) from 1998 - 99 to 2021-22. The varietal replacement rate (VRR) is high, 43.30 %, for the varieties that have reached the age of five or less in the recent three years (2019-20 to 2021-22). Additionally, it has been calculated that if the seed chain operates at 100 % efficiency, the BS generated (48.1q) in 2021-22 can cover an area of almost 0.12 million hectares in 2024-25. The study offers an in-depth overview of berseem BS indent and production, an analysis of the difficulties encountered in BS production, and future directions for expanding variety and producing excess BS in the nation.
