RIVERSIDE, Calif. Juicy. Extremely Sweet. Visually attractive. Easy to peel. Low seeded. These are the fine qualities that mark 'KinnowLS,' the latest citrus variety released by researchers at the University of California, Riverside.
Large-sized for a mandarin, the fruit has an orange rind color. The rind is thin and extremely smooth. The 10-11 segments in each fruit are fleshy and deep orange in color.
'KinnowLS' (the LS is short for low seeded) is a mandarin selection developed by mutation breeding of the mandarin cultivar 'Kinnow,' a mid-to-late season maturing variety developed by UC Riverside nearly 100 years ago. While 'Kinnow' has 15-30 seeds per fruit, 'KinnowLS' has only 2-3 seeds per fruit. Rarely, individual 'KinnowLS' fruit may have 4-7 seeds.
"People who like very sweet fruit are going to find 'KinnowLS' to be very appealing," said Mikeal Roose, a professor of genetics in, and chair of, the Department of Botany and Plant Sciences, who developed 'KinnowLS' along with staff scientist Timothy Williams. "When other citrus varieties mature to reach the level of sweetness of 'KinnowLS,' their other qualities such as rind texture are in decline. Neither 'Kinnow' nor 'KinnowLS' suffer in this way."
Yet another attractive quality of 'KinnowLS' is that it can be grown in California's desert regions because the fruit, which matures during February through April, does well in hot climates.
'Kinnow' is the most important mandarin in the Punjab regions of India and Pakistan, where 'Kinnow' fruit trees constitute about 80 percent of all citrus trees.
"But the fruit, which is popular there, is seedy," Roose said. "Therefore, 'KinnowLS' has very good potential in this area of the world."
