Abstract

The melon plant is one of the plants with agronomic potential adult among the vegetables, for presenting high productivity in a short time. In Brazil the main producing areas are located in the owed semiarid the favourable conditions of climate for the culture, however, that area presents some factors limitations, mainly as the salinity of the soil and of the water, what carts in the decrease in the productivity and in certain cases total loss of the cultivation. The objective of that work was to accomplish a growth analysis in cycles of melon plant selection developed in a saline environment. The experiment was executed from March to May of 2017 in the Federal University of Alagoas. The appraised treatments were six cycles of melon plant (C1, C2, C3, C4, C5a and C5b) selection. The used design was in randomized complete block design in subdivided portions, being the six selection cycles the portions and the six evaluations biometrics in the time the subplots, with four repetitions. The subplots were divided into two stages in agreement with the presence of the characteristic in the vegetative stage of the plant, in that were appraised vegetative and reproductive variables. Variance analysis and test were accomplished from Tukey to 5% of probability, besides the obtaining of the earnings for selection. To determine the variable of larger importance the technique of main components it was used. Among the cycles C1 and C5a there was an increase of 15,89% of the number of leaves, that is due mainly for the small ones won to each election cycle. The selection cycles accomplished in the melon plant population promoted a small reduction in the percentile of matter dries to each selection cycle, not presenting significant difference among the cycles, with averages of 13,92; 13,10; 13.05; 12,62; 11,94 and 12,28%, respectively for the cycles C1, C2, C3, C4, C5a and C5b. NL and NFB explain about 85% of the total variation found among the selection cycles. NL presented the largest importance in the vectors and it presented correlation with several characteristics, like LMS (0.99), LSS (0.90), NBFF (0.80) and % MSPA (0.91). The selection cycles presented genetic progress as the tolerance the salinity. The number of leaves is the characteristic to be selected for obtaining of tolerant superior genotypes the salinity.
