FOR THE FIRST TIME IN INDIA

SEEDLESS KINNOW DEVELOPED BY PAU HORTICULTURIST

 

Kinnow mandarin which was brought into Punjab in fifties has now emerged as the main commercial mandarin variety now of not Punjab only, but even of North West India.  The total area under kinnow in Punjab, Haryana, Rajasthan and Himachal Pradesh is estimated to be 1,02,018 hectares and the total annual production is 14,30,000 tons.

         One of major drawbacks of kinnow orange is the excessive seed content of fruits.  The fruits on an average contain 25-30 seeds.

         Fruit breeders at many places have been trying to improve this variety and trying to develop a strain that is either seedless or nearly seedless.  A seedless strain of kinnow has already been developed in United States.  Pakistani fruit breeders are also working on it.  This has now been achieved at the Punjab Agricultural University (PAU), Ludhiana by Dr. H.S. Rattanpal, a senior horticulturist in the Department of Fruit Sciences

         This fruits of this kinnow does not contain more than 3 seeds, which is negligible of the seed content of 25-30 seeds common type.  So this new strain can be called “seedless” in layman’s language.

Seedless strain of Kinoow developed in the United States

         This strain is a mutant and the mutation was created by gama rays irradiation.

         This is a very valuable creation. So the breeders are keeping the plants of this new strain under high security in wire mesh cages. The breeders fear that someone may not steal the budwood from the mother plant before the variety is officially released for farmers’ use.

          The PAU scientists still want to test some quality parameters of this strain for some time more before releasing it to farmers.
