High yielding cocoa varieties of the Central plantation crops research institute India
The cocoa breeding programme of the Central Plantation Crops Research Institute (CPCRI) encompasses germplasm collection, evaluation, selection and hybridization. The hybridization activities were conducted from 1983 onwards to develop high-yielding varieties with specific characters. The hybrids were established in four progeny trials to assess their performance. One clonal trial was conducted with the objective of developing high-yielding clones. The major objectives of these programmes were to develop superior hybrids and clones with distinct evidence of heterosis and medium canopy size that can easily be accommodated in arecanut and coconut gardens. These activities resulted in the identification of two hybrids; I-56 x II-67 and ICS 6 x SCA 6, and a clone, NC- 45/53, that have high yields, an early bearing habit, medium canopy size and superior bean qualities.
