Duration and rate of the grain filling period and subsequent grain yield in crosses between facultative and winter wheat cultivars (Triticum aestivum L. em Thell)

Creator:

Mou, Beiquan

Abstract:

Concerns about the genetic control and environmental influence of various stages of development including the grain filling period, and the relationship between early maturity and grain yield prompted this study. The experimental material consisted of two facultative and two winter wheat cultivars. A dial!el cross, excluding reciprocals, was also developed...

Nature of inheritance and association of time, duration and rate of grain filling and subsequent grain yield in crosses of winter and spring wheats (Triticum aestivum L. em Thell)

Creator:

Choi, Byung Han

Abstract:

The nature of inheritance and possible associations for traits influencing earliness and grain yield were investigated using a four parent diallel of winter and spring wheat cultivars. More genetic variability was observed for the traits measured in segregating populations resulting from crosses between winter and spring type wheats in contrast...

Identification and development of cultural practices for upland rice production systems for savanna soils of Colombia

Creator:

Leal-M, Dario

Abstract:

A great potential for increasing upland rice production exists in the savanna soils of Colombia. These vast areas are currently underutilized. However, they have good soil structure, flat topography, coupled with sufficient and well distributed rainfall, making savanna soils ideal for upland rice cropping system. The major constraints to upland...

Aluminum toxicity studies in rice (Oryza sativa L.)

Creator:

Martinez-Racines, Cesar P.

Abstract:

A nutrient solution technique developed for wheat was used to determine tolerance of rice cultivars to aluminum (Al) toxicity. Pre-germinated rice seed was placed on top of a screen and allowed to grow on the Al-free solution for 72-96 hours or until the primary root was 2-3 cms long. Seedlings...

Influence of aluminum toxicity in intergeneric crosses of wheat and rye

Creator:

Lopez-Benitez, Alfonso

Abstract:

A technique previously designed to screen wheat cultivars and segregating populations for tolerance to Aluminum utilizing nutrient solutions in growth chambers was found to be efficient in differentiating among cultivars of wheat, rye, and triticale for tolerance to Al under greenhouse conditions. A 5°C increase in temperature, from 25°C to...

Genetic variability and association between agronomic and quality characteristics in twenty-nine female genotypes of Humulus lupulus L.

Creator:

Roberts, Donald Day

Abstract:

The genetic variability in and association between 14 traits that affect maturity, yield, and chemical properties of its product. The plant characters measured were: vigor, flowering date, harvest date, yield, lateral length, nodes per lateral, cones per lateral, cones per vine, cone weight. Alpha-acid and beta-acid content of the cone,...

Evaluation of four quality factors in a selected winter x spring wheat cross (Triticum aestivum Vill., Host)

Creator:

Schumaker, Karen Sue

Abstract:

The nature of the genetic variation associated with a cross involving winter and spring wheat parents for four quality factors was evaluated. Yamhill, a soft white winter wheat, and Inia 66, a hard red spring wheat, were selected as parents for this study. They represented distinctly different phenotypes for the...
