Determination of Yield Components and Fruit Quality Characteristics of Promising Local Winter Squash (Cucurbita maxima Duch.) Cultivar Candidates in Different Locations of Samsun Province
Abstract
The interaction between
various cultivar candidates were developed by breeding programs and different
environmental conditions are important. This criterion that demonstrates the
real performance of genotypes. It can be revealed that which genotypes are
better to adapt good environmental conditions, where genotypes are better to
adapt unsuitable environmental conditions or which genotypes are showing good
or poor stability in all locations by means of genotype × environment
interaction. In this study, it is aimed to determine the
performances of some fruit quality characteristics and yield components of
local promising winter squash cultivar candidates (55ÇA15, 55ÇA06 and 57Sİ21)
which are developed by selection breeding methods from Black Sea Region winter
squash populations in three different ecological conditions (Bafra, Tekkeköy
and Salıpazarı) of Samsun province. It was determined that there were
significant differences winter squash genotypes and locations in terms of fruit
dimensions and fruit rind thickness values. However, fruit flesh color and
total soluble solid content (TSS %) values were not statistically significant.
In comparison with the yield values of the pumpkin cultivar candidates, 57Sİ21
(21 t ha-1) showed the best performance. This genotype was followed
by 55ÇA15 (17 t ha-1) and 55BA03 (17 t ha-1). In terms of
average fruit weight, 57Sİ21 genotype was found to be more stable than the
other genotypes due to below 1 regression coefficient, positive regression
constant, Sd2 value close to 0 and 0.86 r2 value.
Similarly, 57Sİ21 was found to be more stable than Arıcan-97 cultivar in fruit
flesh hardness. As a consequence; 57Sİ21 genotype compared to other genotypes;
yield and fruit number values were higher and fruit weight, and fruit flesh
firmness values were found to be more stable. It was determined the most
promising genotype for Samsun ecological conditions. In the next years, cultivar registration procedure for this
genotype will be initiated. Thus, a new winter squash cultivar will be released
into production for Turkey.
