Abstract	Grass pea (Lathyrus sativus L.) family leguminosae is cultivated as an important food and feed crop all over the world. It is very recalcitrant and difficult to regenerate and root under in vitro conditions. In this cotext, the study was carried out in three steps to find out the effects of three auxins [naphthalene acetic acid, indole 3 butyric acid, indole-3-acetic acid (IAA)], four sucrose concentrations and six types of substrate most suited for plant growth and helpful in acclimatisation of grass pea. The results showed that 2 mg L$^{−1}$ IAA, 3 % sucrose was most suitable for rooting of grass pea. When different concentrations of sucrose were supplied to optimum concentration of IAA in Murashige and Skoog medium, 4.5 % sucrose concentration induced maximum number of 13.70 roots per explants that had positive impact on root length, fresh and dry weight of roots, plant height and morphology of the growing plants. There was 92.66 % acclimatisation and survival rate of these plants using peat moss compared to five other substrates used in this study. The developing plants were vigorous, flowered and set seed contained in pods under glass house conditions. It is concluded that rooting is affected by type and concentration of plant growth regulators and type of substrate has direct bearing on acclimatisation, flowering, pod and seed set of grass pea. As such this paper reports an efficient rooting and acclimatisation system of grass pea that will be very useful in future genetic transformation and breeding for improved characteristics.
