The influence of maternal and fatherly parental forms on the effectiveness of reciprocal crossings in hybrid gladiolus (Gladiolus hybridus Hort.)

In 2007 and 2009 at the Department of Floriculture of I.V. Michurin All-Russia Research and Development Institute of Horticulture the researches of the influence of maternal and fatherly parental forms on the productivity of reciprocal crossings in gladiolus were conducted. Genotypic features affected both seed efficiency and morphological parameters of fruits and seeds. For example, in combinations Lyudmila x Spartan and Spartan x 55-07 seed boxes were larger, and the average content of seeds in them reached very high values (34-35 pieces of seeds). In reciprocal crossings the greatest efficiency was reached in the combination Svetophor x Typhoon - seed efficiency made 27.5 pieces of seeds, in return case (Typhoon x Svetophor) - 69.3 pieces. Two couples reciprocalcrossings - Pavliny Glaz x 301-09 and Sinyaya Ptitsa x Ogni Mayaka - gave high seed efficiency in two cases. The values fluctuated in insignificant limits (38.3-49 pieces of seeds). In general on the varieties of initial form the results of crossings influenced approximately equally, but with small advantage of maternal form...
