PHENOTYPIC STABILITY FOR YIELD OF TEA (CAMELLIA SINENSIS L) IN DAR]EELING

Abstract

Tea grown in Darjeeling is famous for its aroma in the international market. TIle fluctuations in yield over the years impede the growth of tea economy in Darjeeling. For sustainability of economy, it is imperative to identify the stable genotypes with high yield and quality. Therefore, an investigation was carried out over five years (1990-1994) in Darjeeling where 9 promising genotypes (clones and seed stocks) were evaluated for yield stability in randomised block design with three replications at 105 cm x 45 cm x 45cm spacing at Clonal Proving Station, Ging Tea Estate.
