The values of GCA,SCA and heritability of 5 main quality characters(vitamine c,dry matter,protein content,total sugar content and cellulose) in 5 new male sterile lines and 6 inbred lines of radish were analyzed with the incomplete diallel cross method.
COOPERATIVELY BREEDING NEW HYBRID RICE COMBINATIONS BY USING INCOMPLETE DIALLEL CROSS METHOD.I.ANALYSIS ON THE PERFORMANCE OF GRAIN YIELD AND OTHER IMPORTANT CHARACTERS OF HYBRID COMBINATIONS
The survival rate of the autotriploid plants obtained by the conventional cross method was very low ( 0.07% ), but that obtained by ovary culture method was higher (0.78%). Which surpassed 11.14 times than that of the former.
Exactly to test both the methods for mapping, Fisher information content was applied to prove that the three-point self cross method is powerful for mapping.
The result showed that, like MAPMAKER program, the three-point self cross method is Powerful to detect linkage relationship among loci, to order them on linkage groups and to calculate distances between nearest neighbor loci. Besides, this method could provide us with the other information of map such as the positive or negative interference and couple or repulsion configuration.
The 14 maize inbred lines in Ningxia and 2 ordinarycorn inbred lin es crossed with 5 inbred lines of Mo17, Dan340, Ye478, Huangzao 4, B73 from Reid , Lancaster, Tangsipingtou, Ludahonggu were analyzed by Diallel Cross Method.
Using model Ⅱ of Griffng Diallel Cross Method 2, eight wheat genotypes with different uitilization efficiency of nitrogen and phosphorus were selected to study genetic principles of wheat traits relevant to nitrogen and phosphorus efficiency. All seeds were divided into two parts: one part were planted in normal environment with fertilizer, the other were planted in starving environment without fertilizer.
Additional cross method was used to improve some defect characteristics of G17AB watermelonmale sterile line,such as:weak growth in seedling stage; susceptible some diseases; low yield potten-tial.
Subjects were male health volunteers. Using random cross method of two periods, HPLC detected the blood drug concentration of Omeprazole in volunteers after taking the experimental drug and the comparison drug (single oral dose 40mg Omeprazole enteric coated tablet).
The paper introduces how to check the correct and error of wire connection of 3-phase electric meter by the B phase voltage method and the voltage cross method, and points out that when the wire connection is examined with the voltage cross method after the A phase is broken, the wire connection method reversing the meter is right.
The broad-sense heritabilities obtained by the diallel cross method were 0.931 and 0.623 for males and females, respectively, and the narrow-sense heritabilities were 0.068 and 0.166 for males and females.
In the convergent cross method, single crosses between inbreds, and double crosses were performed in 1995, and 1996, respectively, as the first step to create EPS20c and EPS21c.
Each variety was built using both alternative methods: i) controlling the balanced contribution of each parental inbred (convergent cross method), and ii) randomly mating a seed mixture from the eight inbreds (random method).
Depending upon the final objectives, one of the breeding methods, viz., recurrent selection, heterosis breeding, back-cross method or full-sib selection (bi-parental mating) may be followed.
