Grouping of Rice Breeding Lines According to Coefficient of Parentage and the Relationship between Severity of Leaf Blast
, Eating Quality and Coefficient of Parentage.
Ab; CP between 'Kanto' lines formed clusters relating to 'Koshihikari', 'Kotikaze' and 'Nipponbare'. There was a cluster having low CP with 'Koshihikari'. Significant correlation between CP and eating quality was not found at breeding lines with good eating quality and high resistance of leaf blast. Good eating and high disease resistance with wide genetic background could be combined. (text)

It was less than 0.1 of ever-bearing cultivars except 'Summer Princess' and 'Kiminohitomi'. Crossings among 15 June-bearing cultivars resulted CI from 0.067 to 0.440 and average 0.210.

Relationship between the Coefficient of Parentage and Sugar Yield in Sugar Beet
Ab; The correlation between the CP and sugar yield was R2=0.92. The CP increased by 0.1 and the sugar yield decreased by 4%. In the majority of the hybrids with a high yield, the CP was below 0.1. In this study, program for outcross crop was used assuming that common ancestor had CI of 1 for self-fertilized parent and 0.5 for male sterile parent. Changing the latter value 0.3 - 0.6 resulted no large discrepancy. (text)

Relationships between Coefficient of Parentage and Genetic Distance Based on DNA Polymorphism in Barley
Ab; A significant correlation (-0.526 to -0.650) between CP and Nei's genetic distances was found among 22 cultivars. Thus, the validity of the CP between two cultivars, which are calculated assuming that cultivars derived from the crossing have half of the genetic materials of each parent, was supported by the genetic distance estimated from DNA polymorphism.
