Rathna K-2 mango is an improved hybrid variety developed in India, popular for its high yield and good fruit quality. The fruits are medium to large, oval to oblong, with smooth yellow skin when fully ripe.

The pulp is deep yellow to orange, soft, juicy, and nearly fiberless, with a pleasant sweet taste and mild aroma. This variety is suitable for table purpose, as well as for pulp extraction, juice, and processing.

The tree is a medium-sized, vigorous evergreen and a regular bearer, making it suitable for commercial cultivation. Rathna K-2 mangoes generally ripen during the mid-season (May–June) and are appreciated for their uniform fruits, good keeping quality, and market demand.
