Abstract
Celery (Apium graveolens L.) is one of the important crops in Apiaceae family. It is cultivated
worldwide for food as well as for use in pharmaceutics as it is an excellent source of vitamins,
phenolic compounds, volatile oils and other nutrients. Identification of superior genotypes
with improved biochemical and agronomic traits is essential to develop varieties for
commercial cultivation. The present study focused on characterization of celery genotypes for
economic traits. The performance of 20 celery genotypes over two locations during rabi
2019-20 and 2020-21 was investigated using GGE biplot analysis. The major factors
influencing traits were genotypes, locations, as well as their interactions. Correlation analysis
revealed a positive and significant association of seed yield with secondary branches and the
number of umbels per plant. Biochemical profiling of microgreens, leaves, stalks and seeds of
celery genotypes was carried out. Antioxidant activity (40.95 to 60.49%) and crude protein
(28.81 to 39.94%) contents were highest in microgreens. The study revealed high content of
total phenols (7.59 to 13.93 mg/g FW), total soluble sugars (20.49 to 27.77 mg/g FW),
reducing sugars (10.24 to 14.83 mg/g FW), phosphorus (5.2 to 6.8 mg/g DW), iron (0.40 to
0.54 mg/g DW), copper (0.015 to 0.026 mg/g DW), ascorbic acid (0.70 to 1.77 mg/g DW),
total soluble proteins (173.54 to 201.54 mg/g FW) and tocopherol (10.45 to 14.89 mg/g FW)
in seeds. The concentration of total chlorophyll (1.03 to 1.54 mg/g FW), Chl a (0.80 to 1.45
mg/g FW), carotenoids (0.29 to 0.43 mg/g FW), non-reducing sugars (14.41 to 19.42 mg/g
FW), and potassium (20.3 to 26.1 mg/g DW) were found highest in leaves harvested 60 DAT
while that of Chl b (0.28 to 0.61 mg/g FW), zinc (0.11 to 0.19 mg/g DW), manganese (0.017
to 0.028 mg/g DW) were observed highest in leaves harvested 90 DAT. Highest contents of
sodium (5.2 to 8.0 mg/g DW) and calcium (41.5 to 51.3 mg/g DW) were found in stalks
harvested 60 DAT whereas crude fibre content (16.39 to 20.86%) was highest in stalks
harvested 90 DAT. The study revealed the presence of total oil (17.30 to 24.05%) and
essential oil (1.27 to 2.47%) in seeds of celery genotypes. Based on biochemical profiling and
agronomic traits, four genotypes, namely, PAU3, PAU8, PAU16 and PAU18 were found
superior in terms of seed yield and biochemical composition. Characterization of celery
genotypes based on biochemical composition and yield components clustered them into four
different groups.
