The yield of plant is a complex character and is governed by several factors. The present investigation was carried out with ninety genotypes of fennel along with three checks namely Pant Madhurika (Pantnagar, Uttarakhand), GF-11(Gujarat) and RF-125 (Rajasthan) in Pantnagar (Uttarakhand) during 2009-10 and 2010-2011 to estimate relationship between yield and yield-components by correlation coefficient analysis. The analysis shows that yield shows highly significant and positive correlation with plant height upto main umbel (0.375), plant height upto top of plant (0.446), number of primary branches (0.290), number of secondary branches (0.303), seed yield per plant (0.982), number of fruits per umbel (0.324) and number of fruits per umbellate (0.364) and positive and significant correlation with number of umbellate per umbel (0.219), thus indicating the importance of these traits as components for yield.
