Modern condition of systematization of soybean Glycine max (L.) Merrill

OIL CROPS. Scientific bulletin. VNIIMK, 2006, iss. 1 (134). On the basis of the critical analysis of existing botanical classifications of a soybean the intraspecific classification of a soybean subdividing species G. max (L). Merrill on three subspecies: ssp. manshurica (Enk.) Zel. et Koch., ssp. gracilis (Skv.) Zel. et Koch., and ssp. max (L.) Zel. et Koch. is offered. With the purpose of simplification of morphological-biological sistenatization of a breeding material own soybean conculta's classification (cc.) is offered. A key for definition and the description of 9 concultas of the North Caucasian ecologically-geographical group of manchurian subspecies ssp. manshurica (Enken) Zelentsov et Kochegu-ra are given: cc. superpraecox Zel. et Koch. - superearly; cc. praecox (Enk.) Zel. et Koch. - early; cc. terminalis Zel. et Koch. - determinant; cc. medicaulis Zel. et Koch. - middle-stem; cc. athlanta Zel. et Koch. - powerful; cc. giperathlanta Zel. et Koch. - super-powerful; cc. procerella Zel. et Koch. - early indeterminant; cc. procera Zel. et Koch. - late indeterminant.
