Abstract: Through carrying on the regional test in seven representative test points in Heilongjiang Province to the potato new variety about the bumper crop, the stable production, the region compatible and so on, finally indicated: The fresh food strain Ke9723-20 compared to comparison Kexin2 increases 11.5 points. The production increase is extremely remarkable also the performance stable production, the compatibility is broad, hopefully through variety examination and approval. Mid-precocious material Biology Center 202 compared to comparison Kexin4 increases 10.6 points. But the compatibility is not good, may piant in Hailun as well as the ecological condition similar area. The high starch material Ke20029-36 increases 4.5 points compared to the comparison. These two materials display general in this experiment, should be further experimented to determined whether it can be carried on the promotion.
