  sugarcane parents
Transgenic sugarcane parents containing multiple copies of herbicide resistance (bar) and Sorghum mosaic virus (SrMV) resistance (hut) genes were crossed with non-transgenic sugarcane varieties.
      
This is the first report of transgene segregation in sugarcane, and we have demonstrated that transgenic sugarcane parents showing stable inheritance of transgenes can be effectively used in breeding programs.

General and specific combining ability for five main economic charac- ters of nine parental clones of sugarcane were estimated in a 5×4 incomp- lete diallel design.The results showed that general combining ability(gca) was significant for five characters except gca of the male parents for plant height;specific combining ability(sca)was significant only for plant height and brix.The heredity for the characters in question of the parental clones and the use value of the parental clones in sugarcane cross breeding...

General and specific combining ability for five main economic charac- ters of nine parental clones of sugarcane were estimated in a 5×4 incomp- lete diallel design.The results showed that general combining ability(gca) was significant for five characters except gca of the male parents for plant height;specific combining ability(sca)was significant only for plant height and brix.The heredity for the characters in question of the parental clones and the use value of the parental clones in sugarcane cross breeding were evaluated on the basis of their average performance,gca and sea effects, and sea mean square.The analysis suggested that CP28-11 was a better female clone to transfer high sucrose to it's progenies,Ya71-374 was the most desirable male clone for it's progenies having high sucrose content and high yield.According to the performance of F_1 population,the better crosses were Xuan15×Ya71-374,Co997×Ya71-374 and CP28-11×Ya73-512.

采用5×4不完全双列杂交设计,估算了9个甘蔗亲本无性系的5个主要经济性状的一般配合力和特殊配合力。方差分析表明,除父本株高外,5个性状的一般配合力达差异显著水准,特殊配合力只有株高和锤度两性状差异达显著水准。根据性状的平均表现、一般配合力效应、特殊配合力效应和均方,评价了亲本无性系有关性状的遗传特点及其在甘蔗杂交育种上的应用。CP28—11作为母本能把其高糖特性传递给后代,崖71-374是最理想的父本,其杂种后代表现高糖高产。F_1代群体表现较好的组合有:选15×崖71-374,Co997×崖71-374和 CP28-11×崖73—512。

The photoperiod induction of sugarcane parental varieties in Louisiana State University,Louisiana,United States in 1984 is discussed.93 of 97 parental varieties flowered after 6 kinds of different photoperiod treatments, the flowering times of 80% varieties were concentrated on 3 weeks and in- creased the efficiency of making the desired crosses.These results indicated that it is easy to carry out hybridization of sugarcane in Temperate Zone under artificially controlled environmental conditions.This may be a valu- able reference for the breeding and selecting new sugarcane varieties in sugarcane producing provinces such as Fujian,Zhejiang,Jiangxi,Yunnan, Guizhou and Sichuan in our country.

本文讨论了美国路易斯安那州大学1984年甘蔗亲本品种的光周期诱导。经六种不同的光周期处理,97个亲本品种有93个抽穗开花,其中80%的品种抽穗开花时间集中在三周内,有利于杂交组合的选配。这些结果说明温带地区通过人工控制环境条件,可以顺利开展甘蔗的有性杂交育种,对我国闽浙赣云贵川等甘蔗产区的新品种选育有参考价值。

Based on the Euclidian distance measured on 7 economic characters by using phenotyhic clustering method, 40 sugarcane genotypes were grouped into 6 clusters from which 24 genotypes were selected. The genetic clustering analysis was subsquently applied to classify the 24 genotypes into 5 clusters on the basis of the Mahalanobis' distance measured on 6 economic characters. It was found that early maturity genotype FIN79-8 from Indonesia as well as mid-maturity genotype FIN79-9 from Mauritius, both had high cane...

Based on the Euclidian distance measured on 7 economic characters by using phenotyhic clustering method, 40 sugarcane genotypes were grouped into 6 clusters from which 24 genotypes were selected. The genetic clustering analysis was subsquently applied to classify the 24 genotypes into 5 clusters on the basis of the Mahalanobis' distance measured on 6 economic characters. It was found that early maturity genotype FIN79-8 from Indonesia as well as mid-maturity genotype FIN79-9 from Mauritius, both had high cane yield and sugar productivity. They constituted one cluster which was superior to the other clusters for the performance of characters. Through repeated regional tests in several years and locations, the averaged harvested cane and Sugar yields of these two excellent genotypes increased significantly in comparison with the check varieties. They show good prospects to become new sugarcane cultivars for the Fujian sugarcane growing areas. The results also showed that the clustering analysis was not only an useful tool for guiding the parental choice in sugarcane hybridization, but also proved to be an accurate and efficient method for screening sugarcane clones, perfecting current breeding procedure, and promoting the selection efficiency.

应用表型聚类法,根椐7种性状的欧氐距离把40个甘蔗基因型划分为6个类群,从中筛选出24个基因型。进而应用遗传聚类分析,根椐6种性状的马氐距离把24个基因型划分为5个类群。发现经济性状最突出的类群是由来自印度尼西亚的早熟高产高糖基因型福引79-8和来自毛里求斯的中熟高产高糖基因型福引79-9组成,经多点多年区试验证,这两个优良基因型的平均蔗茎产量和蔗糖产量均比对照种显著增产,可能成为福建蔗区的更新换代品种。结果还表明,聚类分析不仅是指导甘蔗亲本选配的有用工具,而且和稳定性分析一样,也是筛选鉴定甘蔗无性系,完善现有育种程序,提高选择效率的精确而有效的方法。
