Abstract: A mechanized way of date production in changing climatic scenario and ever-increasing population dynamics is needed. Therefore, refinement in pollination techniques may aid in achievement of higher fruit yield. Present investigation was planned to evaluate the effect of different pollination methods on fruit setting percentage, bunch weight, fruit length, fruit size, fruit weight, stone weight, yield per plant and total soluble salts (TSS) in date palm candidate line ‘Hillawi’. This study was conducted at Date Palm Research Sub Station, Jhang, Pakistan during the year 2015 and 2016 (mid-February to end July, respectively). Five pollination methods which include natural (control), placement, manual dusting, dusting with pollinator and dried pollen + talcum powder was implied on female spath. All the pollination techniques significantly influenced the expression of studied traits. Maximum fruit set percentage (61.3%), bunch weight (8.4 kg), fruit length (4.1cm) fruit width (3.5cm), fruit weight (12.45 g) stone weight (1.7g), yield per plant (87.70 kg) and TSS (38.43ºBrix) were recorded when pollen dusting was done with pollinator, as compared to other techniques. Characters association study revealed that fruit yield per plant had a positive and significant relationship with fruit setting percentage, bunch weight, fruit length, fruit width, fruit weight and TSS. Therefore, selection of sucker from mother plant with improved mentioned characteristics could produce date orchards with higher fruit yield. Pollen dusting with pollinator emerged as the most effective pollination technique for improving the quantity and quality of fruit in date palm candidate line ‘Hillawi’.
