Use of combining ability estimates to identify the genetic potential of selected winter parental lines (Triticum aestivum L.em Thell)

Creator:

Masood, Muhammad Shahid

Abstract:

A major factor limiting the efficiency of plant improvement programs is the lack of knowledge as to which parental combinations to make when working with quantitatively inherited traits. The primary objective of this study was to provide information regarding the use of combining ability analysis to predict which cross combinations...

Biosystematics of parsley-ferns, Cryptogramma R. Br., in western North America

Creator:

Alverson, Edward R.

Abstract:

A biosystematic investigation of Cryptogramma section Cryptogramma in western North America has been directed towards resolution of two separate taxonomic questions. Results of this research support the hypothesis that a previously undescribed diploid (2n = 30 II) taxon, C. cascadensis, is present along with the common and widespread C. acrostichoides....

Interrelation of the components of grain yield in a cross between dwarf and semidwarf wheat (Triticum aestivum L.) cultivars

Creator:

Medina, Luis E.

Abstract:

Parents and progeny populations from a cross of 'Stephens'x 'Tibet dwarf' were grown in a spaced-planted experiment to obtain information concerning the nature of inheritance and possible associations between grain yield and the components of yield. Agronomic traits measured on an individual plant basis were: heading date, days to maturity,...
