多抗性番茄新品种杭杂301比较试验

Comparative Test for New Tomato Cultivar “Hangza 301”with Multiple Resistances

对3个番茄品种的农艺性状进行了比较,结果表明:"杭杂301"番茄植株紧凑,生长势弱于"杭杂101",与对照品种"阿乃兹"无明显差异;首花节位着生于7.4叶,始收期比"杭杂101"和"阿乃兹"分别早1、2 d,为中早熟品种;第1至第3花序间隔叶数3.95叶,比"杭杂101"、"阿乃兹"分别多0.35叶、少0.45叶。"杭杂301"结果率77.0%,比"杭杂101"、"阿乃兹"分别高7.3、12.7个百分点。在低温条件下,"杭杂301"番茄非商品果率2.1%,比"杭杂101"、"阿乃兹"分别低0.4和1.6个百分点。"杭杂301"果实幼果无绿果肩,成熟果大红有光泽,果型为扁圆形,单果重210.5 g,属于大果型番茄品种;货架期达21 d,较"阿乃兹"长5 d左右;果实硬度1.81 kg/cm2,较"杭杂101"、"阿乃兹"分别高0.14、0.18 kg/cm2;裂果率4.9%,比"杭杂10"、对照分别低0.3、7.5个百分点;商品性好、风味较好。"杭杂301"前期产量21.1 t/hm2,比"杭杂101"、"阿乃兹"分别高1.8%、2.8%;总产量81.8 t/hm2,比"杭杂101"、"阿乃兹"分别高3.6%、11.9%,与"阿乃兹"达到极显著水平。"杭杂301"对叶霉病和黄化曲叶病毒均表现高抗,对根结线虫表现抗;"杭杂101"对叶霉病表现高抗,对黄化曲叶病毒和根结线虫分别表现为高感、中感;对照"阿乃兹"对黄化曲叶病毒表现高感,对叶霉病和根结线虫均表现中感。

The agronomic characters of three tomato cultivars were compared. The results showed that the plants of tomato cultivar 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 / cm^2,being 0. 14 and 0. 18 kg/cm^2 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 Hangza301 had good commodity and better flavor. The yield of Hangza 301 at earlier stage was 21. 1 t / hm^2,which was 1. 8% and 2. 8%higher than that of Hangza 101 and Anaizi separately. Its total yield was 81. 8 t / hm^2,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.
