Quality of the seeds of МС Lines maternal components of the Bulgarian varieties of sugar beet and semi-sugar beet

Abstract

It is believed that the qualities of seed are crucial for the crop. The purpose of this study is to determine the usefulness of the MS lines – maternal components of certified and supported Bulgarian varieties of sugar beet and semi-sugar beet. The seed control analyses are conducted by the Institute methodology adopted and applied by the supervisory bodies of IASAS – in filter paper at 25 degrees C, where germination energy is recorded on the third day and the germination on seventh day, respectively. The mass of 1000 seeds is regarded, sprouts in a fruit or one fruit, and the number of the fallen caps for single male sterile lines. It is found that the sterility of the lines is 96.1% average and the single fruit 97.4%. The resulting seeds are KE - 80.6% and 90.8% germination laboratory. The average seed yield from different lines reaches 332 kg/ha.
