Abstract

PAIVA, Waldelice Oliveira de; SABRY NETO, Hassan  and  LOPES, Alfredo Gasparim Saraiva. Evaluation of melon inbred lines for plant and fruit characteristics. Hortic. Bras. [online]. 2000, vol.18, n.2, pp.109-113. ISSN 0102-0536.  https://doi.org/10.1590/S0102-05362000000200006.

In order to obtain melon hybrids adapted for growing in the Northeast of Brazil, 29 inbred lines (23 belonging to the cantaloupensis group, 5 to the inodorus and 1 to the momordica group) were evaluated in Pacajus, in the state of Ceará. Two commercial varieties, the hybrid Hy-mark and the cultivar Eldorado-300, were used as checks. It was observed that the average period for fruit ripening was 35.1 days for the cantalupensis group, 30.6 days for the inodorus group and 24.4 days for the momordica group. The highest yield concentration (75.8%), evaluated 70 days after sowing, was attained in a inbred line that does not produce commercial fruits. The yield of the lines ranged from 16.2 t/ha up to 65.1 t/ha, whereas the two commercial varieties produced 28.0 t/ha. Three of the cantalupensis group and all inbred lines of the inodorus group were more productive than both varieties used as check. The average inbred lines soluble solid content was similar to that observed in the two commercial varieties (Brix = 8.6). However, the IM46-00 inbred line was outstanding with a high content of soluble solid (Brix = 12.2%). In general, late inbred lines produced fruits with higher soluble solids content.
