| Abstract | The demand of cashew (Anacardium occidentale L.) for export and local consumption is increasing in the country and there is a gap of 7 lakh tonnes in the production to meet the requirement. Due to pressure on land, the possible way to increase production is to increase productivity by adopting improved varieties. Hybrid vigour was well exploited in cashew. Cashew Research Station, Madakkathara has developed many hybrids through hybridization programmes which are maintained in the farm. In the present study 19 hybrids of stabilized yield along with 11 cross parents and check variety Poornima were evaluated for yield and quality traits during the year 2020-2021. Qualitative and quantitative parameters including those of growth, inflorescence, apple, nut, yield and biochemical attributes revealed a spectacular array of variations among the tested genotypes. Among hybrid population, upright and compact canopy with intensive branching habit, yellowish red flush colour and pyramid shaped loose inflorescence were predominating. Early flowering from October was recorded in 13 cashew hybrids and four parents. Cluster bearing habit was observed in hybrids H03-113/1 (4.65 fruits), H03-55/10 (4.55 fruits) and H03- 53/9 (4.10 fruits). The apple weight varied from16.83 g (H03 55/10) to 137.49g (Priyanka). Nut weight of more than 10g was observed in hybrids H03-21/10, H03- 97/2, H03-36/8, H03-110/1, H03-52/6, H03-52/7, H03-52/5, HO3-95/4 and H03- 18/17 and these can be represented as bold nut hybrids. The average kernel weight varied from 1.62g (H03-55/10) to 4.19g (H03-95/4). Nut yield above 18 kg/tree was recorded in hybrids, H03-92/3 (20.2 kg), H03-52/5(21.5kg), H03-36/8(22.10 kg), H03-110/1(23.40 kg), H03-97/2 (24.50 kg), H03-21/10 (25.20 kg) and in parent, Amrutha (21.3kg) and check variety, Poornima (20.0 kg). In biochemical analysis, TSS ranged from 13.150Brix (H03-18/17) to 17.40Brix (H03-53/9). Vitamin C content ranged from 107.5 to 220.15mg/100ml. Lowest tannin content was shown by hybrid H03-55/11(0.085%), H03-92/3(0.09%) and H03-55/10(0.09%). The hybrids H03-57/4, H03-110/1, H03-113/1, H03-52/5 and xx H03-21/10 and parents, Dhana, Madakkathara-1, Vridhachalam-3, and K-22-1 were less susceptible to TMB. Nut yield per tree was found to possess significant positive correlation with nut weight, kernel weight, apple weight, number of bisexual flowers and shelling percentage. In the principal component analysis 85.92% of total variability was explained by the first three components with an eigen value greater than one. The characters like yield per plant, apple weight, shelling percentage, kernel weight, nut weight and bisexual flowers contributed more towards diversity. Eight hybrids viz., H03-21/10, H03-97/2, H03-36/8, H03-110/1, H03-52/6, H03-52/7, H03-52/5 and H03-95/4 were placed in the first quadrant along with check variety Poornima. Magnitude of heterosis was calculated for 19 hybrids over mid parent (relative heterosis), better parent (heterobeltiosis) and standard variety (standard heterosis). The above eight hybrids along with H03-18/17 exhibited better heterosis. The hybrids, H03-36/8, H03-97/2, H03-110/1, H03-21/10 and H03-52/5 which exhibited heterosis and nut weight above 10g, tree yield above 18kg, kernel weight above 2.5g and shelling per cent above 28 were selected as promising types. Hence these hybrids may be recommended for commercial cultivation. Further studies should be undertaken with different traits for exhaustive evaluation for commercialization. The hybrids H03-52/6, H03 -52/7, H03-95/4 and H03-18/17 having good yield and quality traits can be utilized for crop improvement programmes. |
