POPULATION cytology I. cellular division STUDIES ON liliopsid genus MINOR RETZ. FROM HARYANA AND adj

Abstract

Meiotic studies were performed on seven populations of liliopsid genus minor from Haryana and adjacent Shiwalik Hills. All the presently found out populations are tetraploid (2n=28) with X-7. The cellular division course altogether the populations is found to be abnormal with few quadrivalents, besides traditional bivalents, viscousness in chromosomes, presence of secondary association of Some bivalents, non-synchronous separation of some bivalents at Metaphase-l, cytomixis, presence of bridges and laggards throughout anaphases and telophases, etc. in spite of traditional microsporogenesis, high incidence of spore sterility is found in several populations.
