Efficiency of using indexes method in the comprehensive assessment of the genetic collection in the winter hexaploid triticale

Abstract

The paper presents the comparative assessment results of 53 collection samples of winter hexaploid triticale of various ecological and geographical origin using traditional statistical methods and methods of complex indices (Jk), perspectivity indices (Jp), ecological plasticity (Jsp), Finno-Scandinavian (FSJ), Mexican (Mi), and adaptive potential. By the traditional statistical method, high-yield varieties with high values of individual elements of plant productivity were identified: (k-3717) Kaskad, (k-4071) Ramzay, (k-3969) Trizub, (k-3924) Popsuevskaya, (k-3900) Prometey, (k-4095) Shalanda, (k-4097) Buket. The following varieties were identified by the method of complex indices: (k-3909) Topaz, (k-3717) Kaskad, (k-3931) Skif, (k-4071) Ramzay, (k-3969) Trizub, (k-4074) Valentin-90, (k-4078) Bordo, (k-3924), Popsuevskaya, (k-3968) Interes, (k-3901) Mars, (k-3900) Prometey, (k-4003) Disko, (k-3999) Anvo, (k-3701) Fidelio, (k-4095) Shalanda, (k-4097) Buket. According to the indices’ complex that determine the prospects of the variety, the grain-forming ability of its ear, resistance to lodging, high adaptive potential, the following varieties were identified: (k-3909) Topaz, (k-3717) Kaskad, (k-4020) Zavet, (k-3932) Skolot, (k-4071) Ramzay, (k-4074) Valentin-90, (k-4076) Knyaz, (k-3924), Popsuevskaya, (k-3968) Interes, (k-3966) Ajax, (3965) Pshenichne, (k-3900) Prometey, (k-4003) Disko, (k-4005) Korvetta, (k-3999) Anvo, (k-3701) Fidelio, (k-4095) Shalanda, (k-4097) Buket, (k-3562) Antey, (k-3582) Patriot. The study results allow to speak about the usage efficiency of the indices method for a comprehensive winter triticale assessment.
