- 摘要:
- “晋西瓜7号”是山西省农业科学院园艺研究所以自交系Ja-132-1-2-1为母本，自交系Ja03-2-1-2-1为父本配制而成的小果型西瓜一代杂种。早熟，果实发育期28 d左右。植株生长势较弱，叶片较小。果实圆形，果形指数1.04，果皮绿底锯齿条纹，皮厚0.7 cm，果皮硬度>24 kg·cm-2，耐贮运。果实中心含糖量11.6%、边糖9.5%，果肉大红色，肉质脆，口感风味好。商品果率98%，畸形果率2%，易坐果、丰产性好，平均单瓜质量2.8 kg，667 m2产量可达3 500 kg。西瓜苗期抗枯萎病鉴定，抗性级别为中抗。
- Abstract:
- ‘Jin Watermelon No.7’，selfing line Ja-132-1-2-1 is used as female parent,and its male parent is selfing line Ja03-2-1-2-1.It is a small fruit type watermelon hybrid generation cultivated in Academy of Agricultural Sciences in Shanxi.It is early maturing and the development period of fruit is about 28 days.The potential of plant growth is weak.The leaves are small.The fruit is easy to set.The fruit is round and the fruit shape index is 1.04.The fruit skin is green with sawtooth stripe.The skin thickness is 0.7 cm.The skin hardness is more than 24 kg·cm-2.It is easy for storage and transportation.The content of sugar of fruit in center is 11.6%,and the content of sugar of fruit at the edge is 9.5%.The flesh is red and crisp flesh and good to taste.Commercial fruit rate is 98%,deformed fruit rate is 2%.It is easy to set fruit and has high yield.The average single-weight is 2.8 kg,the yield reaches up to 3 500 kg per 667 m2.During the seedling period the resistance of blight is identified,the resistance level is medium state.
