Evaluation of some Petaloid Type of Male Sterility Inbred Lines of Carrot (Daucus carota L.) in the South Area and South East Area of Romania
AbstractMale sterility of petaloid type is genetic controlled, but is also influenced by some environmental factors especially temperature. These studies aimed to evaluate the inbred lines in order to establish both the phenotypically stability of the male sterile character and general combinative ability regarding their use as female genitor for F1 hybrids. During the 2007-2009 period, three petaloid type of male sterility inbred lines of carrot (LMP14; LMP15; LMP53) developed at the Research and Development Institute for Vegetable and Flower Growing – Vidra, were investigated in comparative trials for evaluation order the growing conditions of the southern part (Research and Development Institute for Vegetable and Flower Growing – Vidra, Ilfov District) and southern-eastern part of Romania (Research and Development Station for Vegetable Growing - Buzau and Commercial Society Petrosu – joint stock company - Braila). Phenotypically stability of the inbred lines was appreciated in flower stage on the basis the male sterile percent grown every year (850 for each line).
