VARIABILITY AND DIVERSITY OF ELITE DATE PALM PHOENIX DACTYLIFERA L. IN DATE GROVES OF KACHCHH (GUJARAT) INDIA

C.M. Muralidharan , D.A. Baidiyavadara
The coastal belt of Kachchh in western India encompasses a unique date palm based agrarian ecosystem mainly developed through seeds. Hence, these groves exhibit a great variability in colour, shape, size and taste of the fruits. Study revealed the presence of ten basic coloured fruits with 47 colour variants in which red and yellow orange colour and its variant shades were maximum. Out of five shape groups observed, the majority were of oblong type. Most of the fruits were of medium size (60.5%) to big (26.0%). The TSS value of the fruits varied from 17 to 47% in which the majority of the fruits were of very sweet category (TSS 21-30 brix %). Two-way anova analysis showed a significant variability in quantitative traits of the fruits among the different villages under survey, signifying the possibility for exploiting the variability for biotic and abiotic stresses and also for conserving the genetic material for genome studies. The relationship among different villages through clustering indicated that the qualitative and quantitative traits were similar in nearby and adjoining villages, whereas it differed significantly among the villages of far distance indicating a possible eco-geographical influence in the expression of these traits.
