WebbThese are produced using male sterility lines [11]. Hybrid cabbage shows strong heterosis, and the use of such hybrids is expanding. The seed is produced using male sterile lines [12]. Most of the male sterile lines used commercially contain mitochondrial genes, but such genes are not readily available in a number of crops. Webb1 maj 2002 · The combined expression of both transgenes in the male reproductive tissues can result in male sterility. However, this strategy requires a pollination control system …

WebbCMS provides an expedient mechanism to produce large populations of male-sterile plants for commercial F1 hybrid seed production. In cases where the F1 hybrid crop must … WebbLarge scale hybrid seed production in vegetables remains handicapped because of high labour cost or unavailability of trained labour for manual emasculation. Wide range of genetic mechanism such as male sterility, use of sex regulators, self- incompatibility and use of chemically induced male sterility eliminate the need for manual emasculation. farming shrouded cloth

The restorer line can be maintained by selfing. B. In the cytoplasmic male sterility, the male sterile phenotype is expressed when the sterile cytoplasm S is coupled with recessive non-functional nuclear restorer of fertility rf genes (on the left ... WebbMost of the requirements of large scale production of hybrid seed can be met: use of genetic markers showed that the male sterility allowed 100% cross fertilization; there was no evidence of a deficiency of insect pollinators near Cambridge; and fertility restoring lines are available. 3. farming shrimp at home
