Abstract
Cashew ( Anacardium occidentale L.), an introduced crop to India was grown initially for soil conservation and afforestation purpose. Only during the middle part of the 20 th century its commercial potential was identified after which the crop has never looked back. India is the first country in the world to exploit the international trade for cashew kernels. Presently, India is the largest processor, consumer and explorer of cashew kernel in the world occupying an area of 9.91 lakh hectare with a production of 6.92 lakh MT having productivity of 749 kg -1 . The state Odisha, being one of the richest sources of diversity in cashew in the country, grown in an area of 1.58 lakh hectare with an annual nut production of 97,000 MT and productivity of 683 kg ha -1 . Low productivity of cashew in Odisha is primarily due to planting of cashew varieties with low yield potential and presence of senile plantations. Hence there is an urgent need for crop improvement in cashew. In this context, collection, conservation, evaluation and utilization of cashew germplasm play a key role. Cashew germplasm having desirable yield attributing traits such as bold nut type(≥7.0g), high shelling (≥28%) , high yield potential(≥2.0 ton. ha -1 ) and cluster bearing type can be utilized in cashew breeding program for further improvement of the crop. The present field trial was conducted at Cashew Research Station, Orissa University of Agriculture and Technology, Bhubaneswar, Odisha during 2003 onwards. Twenty five collected germplasm of 2003 planting were evaluated by adopting Randomized Block Design with two replications. The data recorded during 2011-12 and 2012-13 revealed significant variations for vegetative as well as yield attributing traits among the different germplasm. Cashew germplasm with dwarf plant habit, exhibiting their suitability for high density planting were H 68, H 303, H 367, M15/4, H 1598 and H 1600 (2.42 to 3.83m). Maximum nuts panicle-1 (more than 4) was recorded in germplasm such as V2, V4, M44/3, BPP10/19, BPP 3/28, H 1598 and H 68. In the present study the germplasm such as H 1610, VTH 30/4, H 2/16, H 1608, NRCC- 1, Kankadi, H 255, H 320, H 303, H 367, H 68, M15/4, RP-3 and BPP 3/28 recorded more than 7.0 g nut weight. Similarly, high shelling percentage is a desirable trait in cashew. The germplasm having shelling percentage more than 30.0 identified were V1, V2, V4, VTH 59/2, M44/3, H 320, H 68, BPP 10/19, BPP 3/28 and BPT 40. Identified germplasm having more than 3kg nuts plant-1 were H1610, V4, VTH 59.2, H2/16, H 1608, NRCC -1 H 255, H 320, H 303, BPP 10/19 and BPP 3/28. In future these germplasm can be exploited for crop improvement program in cashew as per breeding objective.
