The experiment was taken up to elicit the information on yield attributes and yield of different ginger (Zingiber officinale Rosc.) somaclones. Ten somaclones of ginger were evaluated in RBD with three replications during 2015-18 at College of Horticulture, Kerala Agricultural University, Thrissur district, Kerala. The growth performance of ten somaclones indicated significant variation at all the stages of crop growth. The somaclones SE 86102 (16.00 days) and SE 8626 (16.33 days) registered least number of days for sprouting. Among the vegetative characters studied, the maximum plant height (107.38 cm) was recorded by the somaclone SE 86102 which was significantly superior to other somaclones and check varieties. Somaclone CHP 118 recorded maximum number of tillers (20.33) and number of leaves per shoot (28.67). The highest leaf area was recorded by C 8632 with a value of 62.12 cm2. Among the rhizome characters recorded, the somaclone CHP 118 gave highest number of primary rhizomes (4.83) which was on par with SE 8626 (4.33) and C 8632 (4.08). The highest number of secondary rhizome was recorded by CHP 118 (10.33) which was on par with SE 8626 (10.06) and C 8632 (10.01). Weight of mother rhizome was the highest in the somaclone SE 8642 (11.00 g) and CHP 118 (10.67 g). Similarly, weight of primary rhizome was highest in SE 8642 (15.73 g), SE 8626 (15.07 g) and CHP 118 (14.86 g). Weight of secondary rhizome was highest in SE 8626 (13.20 g) and SE 8642 (12.33 g). The highest fresh rhizome yield per plant was recorded by somaclone CHP 118 (274.13 g), SE 8626 (266.67 g), C 8632 (259.67 g) and SE 8642 (251.67 g) at full maturity. The highest yield per plot was recorded by somaclone CHP 118 (8.77 kg), SE 86 26 (8.54 kg), C 8632 (8.31 kg) and SE 8642 (8.06 kg). The fresh rhizome yield per hectare was greater than 30 t per hectare and it was maximum in CHP 118 (35.08 t), SE 86 26 (34.16 t), C 8632 (33.24 t) and SE 8642 (32.24 t). It is concluded that somaclones were highly variable in their performance, yield and yield. Four somaclones viz., CHP 118, SE 8626, C 8632 and SE 8642 were identified as high yielders from their upstanding performance though out the growing period with highest yield in CHP 118. This can be due to more number of tillers, leaves per shoot and rhizomes and also weight of primary, secondary and mother rhizomes.
