High Degree

Mulberry exehibits a high degree of polyploidy ranging from haploidy to docosaploidy and its various species are being cultivated for foliage to practice sericulture and edible fruits. Triploid mulberries for sericulture porpuse and higher polyploids are proved to be superior.  The cultivar Suvarna-2 is an improved high leaf yielding triploid in south India. The meiotic behavior of this cultivar has been presented here. Meiosis was highly irregular. Various anomalies such as univalent, bivalents, trivalent, hexavalent, loose association, unequal separation and precocious movement of chromosomes and laggards have been observed in pollen mother cells. These irregularities prevented the formation of viable gamete that leads to pollen sterility.

Abstract In the previous study we obtained a population of interspecific F1 A. cepa × A. roylei hybrids. In this study, in comparison to the parental species: A. cepa and A. roylei, the F1 hybrids were evaluated in terms of plant morphology, pollen viability, microsporogenesis and female gametophyte. Most of the morphological characters of the F1 hybrids were intermediate as compared to those of both parental accessions. In pollen mother cells (PMCs) of the F1 hybrids abnormalities were observed in meiosis as well as at the tetrad stage. Pollen viability of F1 A. cepa × A. roylei hybrids was reduced to 30.1%. In the F1 hybrids, 45.8% of the analyzed ovules showed developmental disturbances, whereas in 26.7% of the ovules necrotic processes were observed.
