一、品种来源新克新4号是利用克新4号的芽变脱毒培养而成的早熟脱毒种薯。1996年从黑龙江省富拉尔基农科所引进原原种,经过3年的培育表现为早熟、优质、高产。二、特征特性较原克新4号早熟、抗春寒、抗旱、抗病,块茎膨大速度快,大薯率高。经脱毒的克新4号生育期65—75天,薯块大而整齐,结薯集中,大薯率87%。薯形遍圆、芽眼浅、薯芽粗壮,黄肉黄皮,风味好、极面、耐
First, the source of varieties New grams of new No. 4 is the use of new grams of germ-free detoxification culture of precocious seed detoxification.

Second, the characteristics of the new than the original 4 grams of early maturing, cold-resistant, drought-resistant, disease-resistant tubers swollen fast, big potato rate. The detoxification of grams of new 4, the growth period of 65-75 days, large and neat potato tubers, concentrated tubers, potato 87%. Yam-shaped round, shallow eyes, potato bud thick, yellow flesh, good flavor, extreme, resistance
