Abstract:

Fourteen cucumber accessions collected from different Northeast states of India were analysed for variations by means of agro-morphological traits and palynological characteristics. Phenotypic variations in fruit length (19.20 cm – 28.33 cm, fruit width 5.0 cm – 7.3 cm), number of locules (3 – 4/fruit), seed length (0.8 cm – 1.2 cm), seed width (0.3 cm – 0.43 cm) and weight of 100 seeds (1.0 gm – 3.4 gm/ accessions) were observed. Variations were also observed in pollen characteristics among the accessions. Size of pollen varies from 40.00 (41.33) 44.00 μm x 46.00 (47.56) 48.70 μm to 48.00 (48.30) 48.60 μm x 52.00 (52.86) 53.40 μm. Variations in P/E ratio, pore diameter and interporal distance was also observed among the accessions. Cucumber genotypes with superior agro-morphological traits were observed to have bigger pollen size, larger pore diameter and interporal distance, indicating a positive correlation between the two. Present study provides useful information which can assist in efficient utilization and improvement of cucumber germplasm.
