 LAI | Bananas rich in Pro-Vitamin A Carotenoids  Classification  Ploidy: 3X Genome: AAA Subgroup: Red Type: Dessert Suspected country of origin: Thailand ITC code: ITC0403  Status  Lai is a dessert banana believed to originate from Thai-land, rich in pro-Vitamin A carotenoids, with at least 48 µg Retinol Activity Equivalent per 100g when raw (on fresh weight basis). This is estimated to meet 12% of the daily recommended intake of Vitamin A of children under 5 years. It is being fast-tracked for potential adoption into the agri-food systems of Eastern Africa. It has been as-sessed on-station and on-farm in Burundi and Eastern Democratic Republic of Congo (DRC). On-station trials are also underway in Tanzania, and Uganda.   Description  Lai has a tall stature. The underlying pseudostem has a predominantly re-purple colour (fig 3)  The leaf petiole is open with spreading margins that are winged and undulating with pink coloured edges. The petiole base  has large dark brown blotches (fig 4,5)  The leaves have an intermediate habit and are green with both sides of the base rounded (fig 6)  The  male bud is ovoid in shape with an inner red-purple colour and an outer purple-brown colour. The apex of the bract is pointed (fig 7)  The flowers have a yellow compound tepal with a translucent cream free tepal. The style and fila-ment are yellow in colour (fig 8)  The fingers are slightly curved and slightly ridged.   The fruit apex is blunt tipped without any flower relicts. The peel of mature unripe fruit is light green in colour  (fig 9)  The pulp colour of a mature finger (unripe) is dark yellow-orange: RHS 9/2 1355U (fig 10)           LAI Fig 3. Pseudostem Fig 1.

Finger Agronomic Traits (Average of 8-10 plants for 3 cycles) Lai Time from flowering to harvest (days) 137.5  Plant height at flowering (cm)  339.2  Pseudostem girth at base at flowering (cm) 88.2  Number of functional leaves at flowering 9.6  Bunch weight (kg)  13.5  Number of hands 5.4  Number of fingers on bunch 66.3  Weight of hand (kg) 2.2  Fruit circumference (cm) 10.6  Fruit length (cm) 17.2  Pro-vitamin A carotenoids Content  Lai contains 746 µg/100g pro-Vitamin A carotenoids when ripe (on fresh weight basis)  This yields 48 µg Retinol Activity Equivalent per 100g which can be estimated to meet 12% of the daily recommended intake of Vitamin A of chil-dren under 5 years (400 RAE µg/day) and 7% of the daily recommended in-take of Vitamin A of adult women (700 RAE µg/day) Values are means of three individual samples on fresh weight basis of bunches obtained from North Kivu, DRC1. 100g of banana is approximately one finger.   The pro-Vitamin A carotenoid content increases as the banana ripens  Lai is a dessert banana that is mainly consumed when raw and fully ripe  References 1.
