Fruit set variation associated with apozygotic reproduction in sugar beet Beta vulgaris L. Fruit set upon apozygotic reproduction was studied for four years in the msSOAN-5 pollen-sterile inbred sugar beet line. The progenies obtained from pollen-sterile plants by apozygotic reproduction had both fruits with normal seeds and parthenocarpic fruits without seeds, which was not an occasional event. Growth conditions proved to strongly affect the fruit set and seed quality. For instance, water deficiency during early plant development increased the proportion of parthenocarpic seeds. Water deficiency combined with a lower temperature during flowering additionally caused a substantial decrease in the total number of fruits.

Abstract

Fruit set upon apozygotic reproduction was studied for four years in the msSOAN-5 pollen-sterile inbred sugar beet line. The progenies obtained from pollen-sterile plants by apozygotic reproduction had both fruits with normal seeds and parthenocarpic fruits without seeds, which was not an occasional event. Growth conditions proved to strongly affect the fruit set and seed quality. For instance, water deficiency during early plant development increased the proportion of parthenocarpic seeds. Water deficiency combined with a lower temperature during flowering additionally caused a substantial decrease in the total number of fruits. Under the same growth conditions, related accessions did not differ in seed productivity, but varied in the proportion of normal (with seeds) and parthenocarpic (without seeds) fruits.
