[Objective] This study was conducted to provide and promote high-yield,high-sugar, high-lodging resistance cane varieties and change the situation of singleness of sugarcane variety in Guangxi. [Method] The variety, Guitang 04-1001(Guitang 42), a progeny of the cross ROC22 ×Guitang 92-66, was bred and evaluated in the aspects of morphological characteristics and production characteristics through the breeding program of a five-nursery-system protocol by both regional and production trials. [Results] Under many years of experiments, Guitang 42 was shown with high stalk, medium to large stalk diameter, easy stripping, good germination, medium tillering ability, and more population of millable stalks; and high resistance to mosaic and pokkah boeng, medium resistance to smut, high drought tolerance, and good ratooning ability. During the five-nursery-system procedure, the average of cane and sugar yield was 95.06-108.87 t/hm^2 and 15.11-16.85 t/hm^2, which were higher than CK by 11.3%-14.1% and 16.0%-18.9%, respectively. In the regional trial in 2011 and 2012, the achieved cane yield of 101.7 t/hm^2, sugar yield of 15.03 t/hm^2 and sucrose contents of 14.46% were higher than CK by 9.26%, 14.45% and0.66%, respectively. In the production trial in 2012, the average cane yield was88.62 t/hm^2, which was higher than ROC22 by 7.9%. Guitang 42 was approved by Guangxi Crop Variety Approval Committee in 2013 and elected to Guangxi Top 10 sugarcane commercial variety in 2014. [Conclusion] Guitang 42 has the characteristics of early maturity, high yield, high sugar content, good ratooning ability, and high resistance to lodging(i.e., good comprehensive traits), and could be popularized in south sugarcane regions in China. 展开更多

[Objective] This study was conducted to develop some new iron yam (Dioscorea opposita) varieties with excellent cooking, eating and nutritional qualities. [Method] The fresh weight per plant, drying rate, dry weight per plant, yield, allan- toin content, water soluble extract content and disease resistance of seven new iron yam cultivars (No.1, No.2, No.4, No.6, No.8, No.9 and No.10) obtained through spaceflight mutation breeding were measured and compared with control (No.11). Then, the nutrition quality of two elite cultivars No. 6 and No.10 was determined by comparing with the control. [Result] The eight iron yam cultivars ranked in descend- ing order of their fresh weight per plant as follows: No.6(0.255 kg)〉No.10(0.254 kg)〉 No.4(0.242 kg)〉No.9(0.237 kg)〉No.1(0.233 kg)〉No.11(0.206 kg)〉No.2(0.191 kg)〉No.8 (0.157 kg). There was no significant difference in fresh weight per plant between No.6 and No.10, but extremely significant difference between No.6 and the control, No.10 and the control. The eight iron yam cultivars ranked in descending order of their drying rate as follows: No.2 (32.641%)〉No.10 (32.230%)〉No.9 (28.223%)〉No.6 (25.174%)〉No.8(25.122%)〉No.11 (25.043%)〉No.1 (24.291%)〉No.4(20.234%). The dry- ing rate of both No.6 and No.10 was higher than that of the control. The eight iron yam cultivars ranked in descending order of their dry weight per plant as follows: No.10(0.082 kg)〉No.9(0.067 kg)〉No.6(0.064 kg)〉No.2(0.062 kg)〉No.1(0.056 kg)〉No.11 (0.052 kg)〉No.4 (0.049 kg)〉No.8 (0.039 kg). The dry weight per plant of both No.6 and No.10 is higher than that of the control. The eight iron yam cultivars ranked in descending order of their allantoin content as follows No.6 (0.484%)〉No.4 (0.467%)〉 No.10 (0.399%)〉No.ll (0.386%)〉No.9 (0.378%)〉No.8 (0.350%)〉No.2 (0.342)〉No.1 (0.325%). The allantoin content of No.6 was significantly higher than that of No.10 and the control. There was significant difference in allantoin content between No.6 and No.10, but no significant difference between No 10 and the control. The eight iron yam cultivars ranked in descending order of their extract content as follows No. 6(20.49%)〉No.2(16.01%)〉No.4(15.54%) 〉No. 10(15.35%)〉No. 1 (14.48%)〉No. 11 (14.10%) 〉No.9(13.88%)〉No.8(11.87%). The extract content of No.6 exhibited extremely sig- nificant difference with that of No.10 and the control, and the extract content of No. 10 was also significantly different from that of the control. The taste of No.10 was dry, soft, floury, sweet and fragrant, better than that of the other seven cultivars. No.6 had the strongest resistance to Gloeosporium pestis and Cylindrosporium dioscoreae. No.10 had a middle resistance to G. pestis and a strong resistance to C. dioscoreae. No.6 and No.10 had higher contents of starch, reducing sugar, pro- tein and ash, lower water content and better nutrition quality than the control. [Conclusion] No.10 can be popularized as a new variety of edible iron yam, and No.6 as a new variety of medicinal iron yam. 展开更多
