A cytogenetic study was undertaken to evaluate various
types of cytomictic variations induced by different types
of abiotic stresses viz. temperature, heavy metal (Pb) and
water stresses on the meiotic cells of Lathyrus sativus L.
Chromosome transfer and cytoplasmic channels between
microsporocytes occurred from prophase-I to telophaseII stages of meiosis. The occurrence of cytomixis and other
meiotic abnormalities were analyzed in comparison with
pollen fertility. Due to cytomixis, various types of
irregularities were noticed resulting into hypo- or
hyperploids which may cause the origin of aneuploids or
polyploids.
