Abstract:
Meiosis is an event of high evolutionary stability that culminates in a reduction of chromosome number. Several abiotic environmental factors such as heat may cause anomalies at genetic level that ultimately impair fertility of the plant. In the present study, the effect of heat stress on various morphological and cytological parameters has been studied in Lathyrus sativus. The most interesting anomaly recorded during the study was the formation of synezetic knot in prophase-l instead of leptotene and zygotene stages. Furthermore, a large number of interesting karyological and cytoplasmic irregularities viz. multivalents, transmigration of chromosomes, bridges, tripolarity, etc. were found among the heat treated population of 48 hr duration in M2 generation.
