ABSTRACT
Plants which contain
unisexual flowers are subjected to genetic degradation and yield capacity
reduction due to the easily cross-pollination.
Sponge gourd, one of species of the Cucurbitaceae
which is predominantly
cross-pollinating, is cultivated to widely use as vegetable in Vietnamese daily
meals. The aim of this experiment was to evaluate the growth potential and
fruit quality including fruit
aroma of sponge gourd inbred lines. Pure line selection has been performed using
self-pollinated method, so that sponge gourd lines would be recovered with high yielding and aroma and thereby recommended for
further crop system in Thua Thien Hue province, Central Vietnam. The experiment
was conducted in a randomized complete block design (RCBD) with three
replications during the winter-spring season in 2017.
Agronomical data were observed and analyzed on seven
inbred lines (1-MN1,
1-MN2, 5-MN1, 7-MN1, 13-MN2, 15-MN1 and 15-MN2) derived from B29
accession (GBVN006904). The results indicated that inbred lines 13-MN2, 1-MN2 and 15-MN1 attained more
highly fruit weight and yield compared to the others. Four inbred lines
consisting of 5-MN1,
7-MN1, 15-MN1 and 15-MN2 still retained
the light aroma after boiling. The inbred lines 1-MN2, 7-MN1, 13-MN2 and 15- MN1 are considered for appropriately using in
breeding program of new luffa.
