Varietal Development in Acid Lime

Description of Innovation:

The Variety “Ajjappa Gowda” was developed by Mr. A. Devaraj by using the selection technique from wild species of the acid lime. The seeds collected from the wild species were used as a parent material for multiplication. Further the crop was mass multiplied by using air layering technique. The air layered seedlings was started bearing from the third year onwards where as the seed propagation techniques needs 7 years for bearing. The variety having the unique characteristics like high number of fruits per plant, soft and thin skin, high juiciness and high yielder.

Practical Utility of innovation:

The fruits are round, big shaped and yellow colour in nature. Due to its high juiciness and soft skin, the fruits are highly suitable for value addition such as juice extraction, pickle making. On an average 100 kg fruits are harvested from single crop which is high when compared to the existing variety cultivated by the farmer (50-60 kg/tree). It is well thrive in rain-fed situations

Detail of the variety

The variety “Ajjappa Gowda” was named after late innovator’s father.

Salient feature of the variety:

  • High number of fruits
  •  Soft & thin skin
  • Juiciness
  • Tall plant height (16 ft)
