DARINA TD, CRISTINA TD AND MĂLINA TD, THE NEW EARLY SOYBEAN VARIETIES CREATED AT A.R.D.S. TURDA PUBLISHEDEugen MUREŞAN, Raluca MĂRGINEAN
The new soybean varieties Darina TD, Cristina TD and Malina TD are the most recent creations of Agricultural Research and Development Station Turda in the field of soybean breeding. The new cultivars were obtained through individually repeted selection of hybrid population accomplished by crossing the cultivars T93- 8966 x Amurskaja, Zefir x Lena and Amurskaja x Simson. The new varieties are characterized by a growing season adequate to the ecological conditions of the area. Their growing season rank is appropriate with the needs of the area , with a maturity group OO, Darina TD, Cristina TD and Malina TD growing season is 122 days, 124 days and 123 days, respectively. Darina TD has a reddish pubescence easily distinguieshed from the eather soybean varieties whose pubescence is grey. At Cristina TD soybean variety the hilum colour is an important characteristic by which, at maturity, the Cristina TD variety may be distinguished from the rest of A.R.D.S. Turda soybean varieties whose hilum are brown, black and grey. Due to the white colour of flowers, during flowering Malina TD is easily distinguished from the others soybean varietie. A high yield potential as compared to the maturity group to which they belong, very high resistance to lodging, shattering, bacterial blight and mildew. This characteristics and features corroborated with high insertion of the basal pods, ensures suitable conditions for mechanized harvesting. Besides this features, the new soybean varieties have remarkable qualitative traits, high protein and oil content. The good behavior of the new soybean varieties, in terms of yield, emphasize with the results obtained within the network of The State Institute for Cultivar Testing and Registering. Darina TD, Cristina TD and Malina TD as compared with the Onix variety. In the period 2006 - 2011, the new soybean varieties were tested at A.R.D.S. Turda, and as a result Darina TD and Cristina TD are significantly distinct as compared to control (Onix ). Remarkable are also the yield potential obtained by the new soybean varieties. The characteristics and features of the soybean cultivars Darina TD, Cristina TD and Malina TD created at A..R..D.S. Turda recommend them as the most adequate cultivars for the Transylvania Plain.
