Studies on extent of polyembryony in salt tolerant mango rootstocks

Abstract

The present study was undertaken to know the extent of polyembryony in three mango rootstocks, namely Olour, Kurukkan and 13-1. Freshly harvested seeds after 10 days were sown in earthen pots (sand: soil: FYM; 1:1:1). The number of seedlings from stones of Olour, Kurukkan and 13-1 were recorded and extent of polyembryony was calculated. The extent of polyembryony was maximum in Kurukkan (74.43%) followed by 13-1 (51.85%) and Olour (33.15%). The number of seedlings per stone ranged from 1 to 5 in Olour & Kurukkan; and 1 to 4 in 13-1 rootstock. The average number of seedlings per stone was maximum in Kurukkan (2.35) followed by 13-1 (1.88) and Olour (1.51).
