The present investigation entitled “Correlation and Path Analysis and Studies in Ajwain (Trachyspermum ammi L. Sprague)” was carried out with fifteen genotypes including three checks. The experiment was conducted in Randomized Block Design with three replication during rabi 2020-2021 at Chilli & Vegetable Research Unit, Dr. PDKV, Akola. The observations were recorded on five randomly selected plants for nine characters viz., days to first flowering, days to 50 per cent flowering, days to maturity, plant height at maturity, number of primary branches per plant, number of umbels per plant, number of umbellates per umbel, test weight and seed yield per plant. The data so obtained was subjected to analysis of variance and selection indices study. In the present study, the mean performance of genotypes revealed a wide range of variability for all the characters. Significant highest mean values were recorded for seed yield per plant in genotype AKAJ-18-13-21 (7.62 g) followed by AKAJ-18-10-21 (7.16 g) and AA-2 (7.12 g). Genotypes viz., AKAJ-18-13-21 and AKAJ-18-05-21 were found to be early maturing among experimental material. The selection indices studies indicated that the individual trait index, number of umbels per plant had the highest relative efficiency (101.507 per cent) indicated the importance of this trait as yield attribute. In this present investigation, selection index based on three characters (number of umbels per plant + number of umbellates per umbel + test weight) showing genetic gain (2.444) and relative efficiency (104.504 per cent) is more desirable and practically possible to use than those based on four or more characters.
