Abstract
The present investigation was carried out at the Teaching Farm, Mondouri, BCKV during 2003-2009. Fifteen cashew germplasms namely BH-6, BH-85, Madakkathara-1, Dhana, BPP-8, H-68, H-105, Vengurla-7, H-303,
H-320, H-1600, NRCC-1, NRCC-2, Vengurla-3 and Jhargram-1 were included for the study.
The first harvest was made during 2004 from 3-year-old grafted plants.
The experiment was laid out in RBD with 3 replications.
Scheduled management practices with fertilizer dose of NPK at 500:125:125 g/plant/year were applied for all plants.
The hermaphrodite flowers/panicle (155.04), nut length (3.34 cm), both nut yield/plant at 6th harvest (3.635 kg) and cumulative yield for 6 harvest (12.179 kg), apple weight (68.24 g), juice content (45.84 ml) and total sugar (10.54%) were recorded maximum in H-303. Maximum sex ratio (0.64), widest nut (2.46 cm), longest apple (5.86 cm), maximum vitamin C (266.25 mg/100 g) were associated with Dhana. The highest nut weight (9.32 g), kernel weight (2.84 g), shelling percentage (30.74%) and kernel of top grade (W180) were associated with Vengurla-7. Minimum harvesting period (30.24 days) and lowest acidity (0.32%) of apple were observed in BPP-8.
Multivariate divergence analysis is used to find out the distances among the germplasms to exploit in future breeding programme.
From the dendogram there were five distinct groups, Group-1: consisting of Vengurla-3 only, Group-2: having H-105, H-303 and H-320, Group-3: consisting of H-68 and NRCC-2,
Group-4: having BH-85, Madakkathara-1, Vengurla-7, H-255, H-1600, NRCC-1 and Jhargram-1 and Group-5 having germplasms BH-6 and Dhana. The germplasm H-303 was found most suitable for the new alluvial plains of West Bengal followed by BPP-8, Dhana and Vengurla-7.
H-320, H-1600, NRCC-1, NRCC-2, Vengurla-3 and Jhargram-1 were included for the study.
