Comparative Test for New Tomato Cultivar“Hangza 301” with Multiple Resistances
摘要
Abstract
The agronomic characters of three tomato cultivars were compared .The results showed that the plants of tomato cul-tivar Hangza 301 was compact, and its growth vigor was weaker than that of Hangza 101, and was not significantly different from that of the control cultivar “Anaizi”.The first inflorescence of Hangza 301 was set in 7.4-leaf nod, and its harvest -beginning date was 1 and 2 days earlier than that of Hangza 101 and Anaizi respectively , so it was a middle-early-mature cultivar .Its interval number of leaves from the first to the third inflorescence was 3.95, which was 0.35 more than that of Hangza 101, and 0.45 less than that of Anaizi .The fruiting rate of Hangza 301 was 77.0%, and it was 7.3%and 12.7%higher than that of Hangza 101 and Anaizi respectively.Under the condition of low temperature in early spring , the malformed fruit rate of Hangza 301 was 2.1%, and it was 0.4%and 1.6%lower than that of Hangza 101 and Anaizi respectively.The young fruit of Hangza 301 had no green fruit-shoulder.Its mature fruit was bright -red and glossy, its fruit shape was oblate, and its single-fruit weight was 210.5 g, thus it was a large-fruit-type cultivar.The shelf life of Hangza 301 reached 21 days, being about 5 days longer than that of Anaizi .Its fruit hardness was 1.81 kg/cm2 , being 0.14 and 0.18 kg/cm2 higher than that of Hangza 101 and Anaizi separately .Its dehiscent fruit rate was 4.9%, and it was 0.3 and 7.5 percent lower than that of Hangza 101 and Anaizi respectively .The fruits of Hangza 301 had good commodity and better flavor .The yield of Hangza 301 at earlier stage was 21.1 t/hm2 , which was 1.8%and 2.8%higher than that of Hangza 101 and Anaizi separately.Its total yield was 81.8 t/hm2, which was 3.6%and 11.9%higher than that of Hangza 101 and Anaizi separately .Hangza 301 was highly resistant to both leaf mould and TYLCV , and was resistant to root -knot nematode .Hangza 101 was highly resistant to leaf mould , highly susceptible to TYLCV , and moderately susceptible to root -knot nematode .Anaizi was highly susceptible to TYLCV , and moderately susceptible to both leaf mould and root -knot nematode .关键词
