Abstract

Evaluation of five sweet orange cultivars, viz. Hamlin, Valencia, Pera, Westin and Natal on four rootstocks, viz. Volkameriana, Swingle citrumelo, Cleopatra tangerine and Rangpur lime was conducted during 2014 and 2015 on four year old plantation in central India (Jalgaon) under sandy loam soil. Maximum plant eight was found in Hamlin on Volkameriana produced while Pera was dwarfest on Cleopatra tangerine as compared to other rootstock scion combinations. Rootstock average value tallest to dwarf plants were Volkameriana followed by Rangpur lime, Swingle citrumelo and Cleopatra tangerine however for scion varieties this order was Hamlin followed by Valencia, Natal, Westin and Pera. Hamlin on Swingle citrumelo produced largest canopy and Pera on Cleopatra tangerine produced smallest canopy volume. Among the rootstocks Swingle citrumelo produced largest and Cleopatra tangerine produced smallest canopy. The maximum scion circumference was observed in Hamlin and minimum in Westin. Valencia recorded maximum value for fruit weight. Maximum juice content was observed in Pera while highest TSS level was observed in Hamlin. Natal followed by Hamlin and Valencia budded on Swingle citrumelo registered higher yield (67.10, 62.6, 59.5 kg plant-1) during 5th year of plantation however lowest yield was observed in Valencia budded on Volkameriana. We could categorize yield in four group very good (>50), good (35-50), average (20-35) and poor (<20). Hamlin, Natal and Valencia on Swingle citrumelo can be grouped into very good yielder, Hamlin, Natal, Valencia on Cleopatra tangerine, Natal and Westin on Rangpur lime and Westin on Volkameriana can be categoral as good yield. Rest of the combinations was in average yielding category except value on Volkameriana was a poor yielder.

Highlights

Citrus is one of the leading economically important fruit crops grown in more than 50 countries under tropical and sub-tropical region of the world with 7.48 million hectares area and 110.0 million metric ton production
The present study investigated the performance of these varieties in term of growth, yield and fruit quality characters to expand varietal diversity and better-quality juice
There were imported as finished plants budded on different rootstocks: Swingle citrumelo (CS), Cleopatra tangerine (TC), Volkameriana (Vol) and Rangpur Lime (RL) from Brazil

Summary

SUMMARY

Evaluation of five sweet orange cultivars, viz. Hamlin, Valencia, Pera, Westin and Natal on four rootstocks, viz. Volkameriana, Swingle citrumelo, Cleopatra tangerine and Rangpur lime was conducted during 2014 and 2015 on four year old plantation in central India (Jalgaon) under sandy loam soil. Rootstock average value tallest to dwarf plants were Volkameriana followed by Rangpur lime, Swingle citrumelo and Cleopatra tangerine for scion varieties this order was Hamlin followed by Valencia, Natal, Westin and Pera. Natal and Valencia on Swingle citrumelo can be grouped into very good yielder, Hamlin, Natal, Valencia on Cleopatra tangerine, Natal and Westin on Rangpur lime and Westin on Volkameriana can be categoral as good yield. Avaliações de cinco cultivares de laranja doce: Hamlin, Valência, Pera, Westin e Natal em quatro porta-enxertos: limão Volkameriano, citrumelo Swingle, tangerina Cleopatra e limão Cravo, foram conduzidas durante 2014 e 2015 em plantação de quatro anos no centro da Índia (Jalgaon) sob solo arenoso. Dentre os porta-enxertos as plantas ficaram menores no Volkameriano seguido de limão Cravo, citrumelo Swingle e tangerina Cleópatra, no entanto, para variedades copa, a ordem foi Hamlin seguida de Valência, Natal, Westin e Pera.
