草莓新品种56-1和56-2生产比较试验

The Production Experiment on the New Strawberry Cv. 56 1 and 56 2

经与对照（全明星）、母本（群星）连续２年露地栽培对比试验，结果表明：５６－１始收期较对照及母本早６ｄ；早期产量占总产量的４３．５％～４６．３％，显著高于对照及母本；最大果重４０～４２ｇ，平均果重１４．５～１６．２ｇ，平均每公顷产量２０５２０～２０７１５ｋｇ，较对照增产９％～１１％，较母本增产１１％～２２％；且早熟、丰产、抗旱力极强。５６－２始收期较５６－１早２ｄ；早期产量占总产量的５２．７％～５４．１％；最大果重４２．２～４３．５ｇ，平均果重１７．５～１８．１ｇ，平均每公顷产量１９０８０～１９２３０ｋｇ；且大果率高、极早熟、结果期集中。

The two strawberry Cv. 56 1 and 56 2 were compared with CK (Jinmingxing) and their maternal Austar in the open for two years.The result indicated that the Cv. 56 1 had the properties of earliness,high yield and good drought resistance.Its harvesting time was 6 days earlier than that of CK and Austar.The early yield accounted to 43.5%￣46.3% of the total yield and the yield was 9%￣11% and 11%￣20% higher than thatofCKandAustar,respectively,with the average yield of 20 520￣20 715 kg/hm 2.The biggest fruit weight was 40￣42 g and the average fruit weight 14.5￣16.2 g.The Cv.56 2 was of strong earliness,good quality, high percentage of big fruit and concentrated fruit set period.The starting harvest time of Cv.56 2 was 2 days earlier than that of Cv. 56 1 and the early yield was 52.7%￣54.1% of the total yield.The biggest fruit weight of Cv.56￣2 was 42.2￣43.5 g and the average fruit weight 17.5￣18.1 g.The average yield of Cv. 56 2 was 19 080￣19 230 kg/hm 2.
