Varieties Comparison Test Of Small Fruit Tomato In Greenhouse And Detection Of Hybrid Purity

Through varieties comparison, density test of greenhouse varieties(combination) tomato and purity testing of tomato and anti-yellow leaf curl virus identification test,draw the following conclusions:1. Through comparative test of 15 small fruit varieties(combinations) tomato in winter and spring, mainly from the growth period, plant traits, fruit traits, fruit commodity, disease resistance, photosynthetic characteristics, yield and production traits of early analysis, integrated indicators, the combination of T10 has long shelf life, suitable for long storage, and the highest yield, delicious taste。2.Through comparative test of 4 small fruit varieties(combinations) tomato in autumn and winter,the yellow leaf curl virus via whitefly by natural propagation in the greenhouse and disease investigation,combination of T8 showed strong resistance, and SSR molecular marker identification, verified it has a certain resistance, in addition, the composition has early harvest, good commodity, high yield, it is comprehensive character better in four varieties tested(combined),which can be cultivated and application popularized in autumn and winter greenhouse in this region.3.Through different planting density test of combination T8,surveyed and analysed that 73500/hm2 plants second inflorescence high fruit,better fruit characters, the highest yield per plot under this cultivation density.4.By 100 pairs of SSR primers for purity detection of tomato T8, primer SSR87 were obtained and amplified by PCR analysis, combination T8 with both band in tests, co-dominant markers, can be used to detect the purity of tomato.
