Under present investigation, AMMI (Additive main effects and multiplicative interaction) model was validated to study and identify the stable genotype in Volvariella volvacea (Paddy straw mushroom) under varied environmental conditions. A slight change in temperature and humidity can cause larger difference in the crop yield. Moreover, the identification of strain selection criteria for better yield is also needed to be identified for genetic improvement. The six strains of Volvariella volvacea (DMRO888, DMRO886, DMRO463, DMRO889, DMRO885 and DMRO484) were cultivated on cotton ginning mill waste substrate for the characterization of their agronomical traits. The correlation studies showed that yield was highly positively correlated with six traits namely total fruit body length (TFBL), Pileus diameter (PD), Gill width (GW), Stipe length (SL), Fruit body weight (FBW)and fruit body number (FBN) while it is negatively correlated with spawn run time (SRT). The DMRO463 was found most stable and average yielder is the all environment. Further the path correlation identified that PD and FBN traits are the best criteria for the selection of high yielding strain in screening experiments.
