| Abstract:
Almond is a valuable nut crop grown in temperate and subtropical regions. Most cultivars are self-unfruitful and require pollinizing cultivars to set fruits. Recently selected self-compatible almonds of indigenous origin were evaluated for their performance under mild winter climates of Himachal Pradesh, India. Observations were recorded on growth, flowering, yield, nut and kernel quality attributes. Selections JKS-184 and JKS-238 were early (1st-2nd wk February) in flowering while Ribba Selection and Tree No.14 flowered late (2nd-3rd wk March). Most of the selections bore smaller nuts with hard shell except Telangi Selection and Tree No.106 bearing large and soft shelled nuts. Nut maturation was mid-season (end June) in JKS Selections whereas it was quite late (end July) in Ribba Selection, Spillo No.3 and 7. Highest nut yield (15.28 kg/tree) was recorded in Spillo No.7 followed by Tree No.14, Telangi Selection, Ribba Selection with lowest yield (6.29 kg/tree) in JKS 184. Kernel recovery (%) ranged from 20.14 in Tree No.14 to 53.79 in Telangi Selection. Minimum kernel oil (43.75%) and protein (18.00%) content was recorded in Tree No.106 whereas maximum oil content in the kernels was 52.40% in Spillo No.3. Kernel protein content was however, maximum (20.40%) in JKS 184. On the whole, an effort has been made here to highlight the distinguishing characteristics and suitability of these self-compatible selections for commercialization. | |
