Abstract:

To screen for high-quality and high-yielding fresh corn varieties suitable for cultivation in Dehong Prefecture，a field evaluation trial was conducted on 10 fresh corn varieties（5 sweet corn varieties and 5 sweet-waxy corn varieties）introduced from the Shanghai Academy of Agricultural Sciences，using sweet corn variety Yuetian 16 and sweet-waxy corn variety Shinuo 2 as control varieties. The trial adopted a randomized block design，with varieties as treatments，to comprehensively evaluate the yield potential，disease resistance，and quality of the tested varieties. The results indicated that among the six sweet corn varieties tested，Shenketian 6 and Shenketian 811 had significantly（p<0.01）higher plot yields than the other four varieties in the same group，with yield increases of 15.7% and 13.1%，respectively，compared with the control in the same group. Among the six sweet-waxy corn varieties tested，Zitiannuo 1316 had a significantly higher plot yield than the other five varieties in the same group，with a yield increase of 21.4% compared with the control in the same group. Therefore，among the six sweet corn varieties tested，Shenketian 6 and Shenketian 811 not only had significantly higher yields than the other varieties in the same group， but also exhibited good disease resistance and excellent quality，showing good adaptability to the local climatic and environmental conditions. These two varieties can be further demonstrated and promoted. Among the six sweet-waxy corn varieties tested，Zitiannuo 1316 had a significantly higher yield than the other five varieties in the same group，along with good quality and disease resistance，making it suitable for further demonstration and promotion. In this trial，sweet-waxy corn variety Heijin 699 demonstrated relatively good disease resistance and the highest quality score，being classified as grade 1 in quality. Considering market demand，an order-based agricultural approach targeting the high-end market can be adopted，with deep processing to increase the overall income of growers，and gradually realize the widespread application of this variety.
