中早熟鲜食马铃薯新品种‘疆薯2号”的选育.

The new potato variety 'Jiangshu 2' was developed from a cross between 'Шyкpoнa' (female) and 'Латона.' (male) through sexual hybridization and selection by the Experimental Farm, Xinjiang Academy of Agricultural Sciences. In 2022, the registration of non-major crop varieties was completed, with the name of 'Jiangshu 2' and the registration number of GPD Potato (2022) 650095. 'Jiangshu 2' is a new medium-early maturing variety for fresh consumption and chip processing. Its growth duration is 78 days. The plant type is upright and the plant height is about 70 cm. It has round tuber with red skin, yellow flesh, smooth skin, shallow eyes and short stolons. For this variety, the number of tuber per plant is 3 with a mean tuber weight of 237 g, and the marketable tuber percentage is 83.70%. It has 21.70% dry matter, 15.60% starch, 2.03% crude protein, 12.10 mg/100 g vitamin C and 0.43% reducing sugar. Taste quality is good. Production trials over several locations from 2017 to 2018 showed that the yield of 'Jiangshu 2' was 2 528 kg/667m2, increased by 25.65% when compared with that (2 012 kg/667m2 ) of the control 'Kexin 1'. 'Jiangshu 2' is resistant to potato virus X (PVX), moderately resistant to potato virus Y (PVY), but susceptible to late blight. This variety is suitable for spring planting in all ecological areas of Xinjiang Uygur Autonomous Region and the area with high altitude. [ABSTRACT FROM AUTHOR]
