| In order to breed new tomato cultivars suitable for solar greenhouse planting in autumn and winter
in Ningxia, 57 new tomato combinations with large fruit were compared in solar greenhouse. By investigating
plant traits, fruit traits, disease index of tomato mosaic virus and yield, the data of single fruit weight, soluble
solid content, disease index of tomato mosaic virus and yield of tomato were comprehensively evaluated by using
DTOPSIS method. The results showed that the top eight combinations were No.53, No.59, No.58, No.61, No.46,
No.9, No.60 and No.15 by applying DTOPSIS comprehensive evaluation, indicating that these eight combinations
had excellent performance. The results of disease index of tomato mosaic virus and yield were basically consistent
with those of comprehensive evaluation. The evaluation results of fruits hardness and soluble solid content were
inconsistent with the comprehensive evaluation results of DTOPSIS, which indicated that resistance to mosaic
virus and yield requirements of tomato cultivars in autumn and winter in solar greenhouse were more important than indexes of soluble solid content and fruit hardness. It was concluded that No.53, No.59, No.58 and No.61
were the excellent combinations suitable for solar greenhouse cultivation in autumn and winter of Ningxia. |
