Kannenberg’s (Francis and Kannenberg, 1978) figures.
The Arena and Pomar cultivars, respectively, with the
highest coefficient of variation and the expression
showed the lowest stability.
Eco Valance Rick and Shukla variance statistics the
second represents the stability of Lin et al (Lin et al.,
1986) respectively. Based on the results of the
variance Shukla, Terra, Vidoc and Alisson cultivars,
respectively, the cultivars are stable, according to the
minimum variance Shukla.
Lin and Binns (Lin and Binns, 1988) proposed
location between the mean-square methods. They
calculated the stability of the isolated location.
Coefficient of variation in space Lin and Binns (Lin
and Bins, 1991) is presented as the fourth parameter
type (Table 2).

2.2 Stability analysis of genotypes based on
regression analysis
The Arena and Fabiola cultivars are with regression
coefficient close to an above-average yield and
average stability and compatibility good. Altesse
cultivar is with regression coefficient close to a below
average performance and general stability and
compatibility poor average. Also, Melody cultivar is
with regression coefficient close to a near-average
yield with moderate stability and consistency the
average public. Euroflor and Joana cultivars are with
regression coefficient close to a below average
performance and general stability and compatibility
poor average. The regression model coefficient of
determination (or diagnosis), which has been proposed
to improve decision-making based on regression The
