Erratic Male Meiosis Resulting in 2n Pollen Grain Formation in a 4x Cytotype (2n=28) of Ranunculus laetus Wall. ex Royle
Two accessions were studied for male meiosis in Ranunculus laetus from the cold regions of Northwest Himalayas.One accession showed the presence of 14 bivalents at diakinesis and regular segregation of bivalents at anaphase I which lead to normal tetrad formation with four n microspores and consequently n pollen grains and 100% pollen fertility.Sec
