Large-scale production of hybrid seed nuts of commercially cultivated palms such as coconut, arecanut, oil palm and date palm is of prime importance due to the high demand for hybrid nuts and their role in augmenting the production of these crops. However, commercial production of hybrid nuts in these crops is impeded by various factors such as height of the palms, cost and availability of labour, low percentage of fruit-setting, seasonal influences like monsoon rains, etc. We report here the development and use of a simple, viable, cost-effective and labour-saving device for pollinating tall palms from ground-level, which is ideal for large-scale commercial production of coconut hybrids, even by farmers. At least four climbs per coconut palm can be saved by this method during the hybridization process. This simple method can enhance the availability of hybrid seedlings at a cheaper rate to coconut farmers. This method of pollination developed for coconut, can easily be adapted to other commercially important palms depending on the bunch morphology.Full Text

Clonal propagation of elite, disease-free coconut palms is a promising technique for producing uniform planting material with high yield and disease resistance. Over the past few decades cloning of coconut has been attempted in a number of laboratories worldwide; however, success has been limited. In the present study, immature inflorescences of 2–12 cm size were collected from West Coast Tall variety and the rachilla segments were cultured on four different media combinations in dark condition. White translucent outgrowths were maximum in Y3 medium supplemented with 4.54 μM 2,4-dichlorophenoxyacetic acid (92%) followed by medium 72 with 41.4 μM picloram, 61.8 μM putrescine and 4.54 μM thidiazuron (TDZ) (87%). After eight weeks in dark, shoot-like outgrowth was noticed more in Y3 III (65%) followed by Y3 I. After eight months dark incubation, the cultures were transferred to 1/2 Murashige and Skoog (MS) with two hormone combinations and high frequency of multiple shoot formation was noticed in 1/2 MS with 5.37 μM naphthalene acetic acid (NAA) and 4.44 μM 6-benzylaminopurine (BAP). Maximum shoot development was observed Y3 medium fortified with 5 μM 2-isopentenyl adenine (2ip) and 5 μM BAP. The individual shoots after development of 3–4 leaves were transferred to 1/2 Y3 medium supplemented with 5.37 μM NAA and 24.6 μM indole-3-butyric acid (IBA), and ischolar_main initiation was observed in 39.28% plantlets. Start codon targeted (SCoT) profiling based on banding pattern of PCR-amplified products confirmed the clonal fidelity of in vitro regenerated coconut plantlets. The study indicates the possibility of developing an in vitro regeneration protocol for coconut using immature inflorescence explants.Keywords
