Deputy of General Director of “North Kazakhstan Scientific Research Institute of Agriculture” LLP - Chaglinka village, Kazakhstan. Sh. Ualikhanov Kokshetau State University. Field experiments to study the quality of different alfalfa accessions in dependence on weather conditions and stand age were carried out during the period from 2011 to 2013 at the experimental field of LLP “North Kazakhstan scientific research Institute of Agriculture” (v. Chaglinka) located in the northern part of the hilly-flat zone of Akmola region of Kazakhstan. The content of crude protein, crude fiber, crude fat, crude ash, carotin, nitrogen-free extractive substance (NFES) and sugar in the studied alfalfa accessions was reported. All research results were processed with the software packages SPSS. The correlation coefficients among some quality characteristics (dry matter weight ratio, crude protein, crude fiber, crude fat, crude ash, carotin, nitrogen-free extractive substance (NFES), and sugar) and the hydrothermic coefficient (HTC) and the leaf fractions were defined. The results of the multifactorial analysis of the SPSS statistical methods showed that many of the observed parameters in varying degrees are linked with the HTC, leaf fraction and among each other. Six of the nine parameters were statistically significant with the HTC. The correlation between the HTC and the protein content, leaf fractions is positively high; crude fat, crude ash - positively average; crude fiber - negatively high; and carotin - negatively average. The accessions with promising characteristics could be used for future breeding programs in Kazakhstan. https://www.biotech-asia.org/vol12_nospl_edn2/dispersive-cluster-and-correlative-analysis-of-some-alfalfa-accessions-under-the-conditions-of-north-kazakhstan/ Alfalfa; Accessions; Crude protein; Crude fiber; Crude fat; Crude ash; Carotin; Nitrogen-free extractive substance (NFES); Sugar; Cluster analysis; Hydrothermic coefficient (HTC); Leaf fractions; correlation
