Two high-yielding cashew varieties developed

They will be released in market soon, says scientist

After years of research, two new high-yielding cashew varieties have been developed at Cashew Research Station in Bapatla.

The two varieties -- BPP-10 and BPP-11 -- will be released in the market soon, according to K. Venkata Ramana, head and senior scientist, Cashew Research Station.

Dr. Ramana said that the new varieties bear more number of fruits per panicle, have high shelling percentage from 28.5 to 29.3 % and high nut weight of 8.1 g and 6.8 g respectively. The mean annual nut yield of these varieties at 12th year of harvest range from 14.7 to 14.9 kg per tree, he said.

As many as 139 genotypes, including 32 varieties, have been collected and were being maintained at the research station. In the past, after continuous evaluation, five high-yielding selections were identified from local germ plasm collection and released as BPP-3, BPP- 4, BPP-5, BPP-6. Besides, four high-yielding hybrids were also released from the research station with names BPP-1, BPP-2, BPP-8 and BPP-9.

In an evaluation of different vegetative propagation methods, the technique of soft wood grafting was accepted as a standard procedure at the research station.

Easy method

“The method is easy, economic and suitable for commercial multiplication in large numbers,'' Dr. Ramana said.

The Cashew Research Station at Bapatla was established in 1955 by the Indian Council of Agricultural Research (ICAR) and Department of Agriculture to improve productivity of cashew crop by developing high-yielding varieties and suitable agro techniques for Andhra Pradesh. The research station was also chosen as one of the sub-centres of All India Coordinated Research Projects (AICRP) on Cashew by ICAR in 1971.
