Abstract
Eightyseven coconut hybrids comprising of 21 different Tall x Dwarf, 10 Dwarf x Tall, 51 Tall x Tall, 4 Dwarf x Dwarf and one three way hybrid were studied. Evaluation at 18th year based on cumulative yield, which is representative of true yield potential, was carried out and three hybrid combinations namely, Chandrasankara (CDO x WCT), Chandralaksha (LO x CDO) and Lakshaganga (LO x GB) were identified as superior hybrid combinations. These hybrid combinations gave 19 to 42% more yield over the commonly cultivated WCT. Among these three hybrids, Chandrasankara (CDO x WCT) was found to give 47% higher copra over WCT. Hybrids Lakshaganga (LO x GB) and Chandralaksha (LO x CDO) performed well under drought situations. The drought tolerance in these hybrids was identified to be the contribution from the female parent Lakshadweep Ordinary. The performance of these three hybrids in relation to other hybrid combinations and drought situations is discussed.
