1. Interspecific Hybridization in Trifolium

Author:
J. Katznelson
Source:
Crop science 1967 v.7 no.4 pp. 307-310
ISSN:
0011-183X
Subject:
Trifolium subterraneum; annuals; backcrossing; flowering; hybrids; interspecific hybridization; males; parents; seeds
Abstract:
... The interspecific relationships among several Trifolium spp. in the section Calycomorphum were studied. Crosses involving T. israeliticum, T. globosum, and T. pauciflorum failed to produce hybrid seed. Crosses among T. subterraneum, T. eriosphaerum, and T. pilulare gave varying results. Complete interspecific sterility was most common; however, 3 F₁ plants (1 plant from the T. eriosphaerum ✕ T. su ...

An investigation was conducted to determine the nature of genetic effects in segregating populations produced by crossing selected progenitor species-derived tobacco (Nicotiana tabacum L.) lines to the tobacco cultivar used in the original interspecific hybridization. Two genetically stable tobacco lines developed from interspecific crosses of N. tabacum ✕ N. sylvestris Speg. and Comes and N. taba ...

Abstract:
... Total alkaloids (predominately nicotine) are important constitutents in flue-cured tobacco (Nicotiana tabacum L.). Due to varying nicotine levels in cigarettes, it is of interest to see what effect varying alkaloid levels in tobacco have on certain agronomic and chemical characteristics of the cured leaf. Experiments were conducted at two locations to develop lines of flue-cured tobacco with diffe ...

Abstract:
... The productivity of cowpea (Vigna unguiculata (L.) Walp.] can be reduced substantially by hot weather during flowering. Inheritance and heritability of tolerance to heat during reproductive development were studied to develop efficient methods for breeding improved cultivars. Heat tolerant (‘Prima’ and TVu 4552) and heat sensitive (Barnbey 23, ‘Magnolia’ and 7964) cowpea genotypes were chosen for ...

Flowers were classified into subtypes, according to stamen (and petal) modification. Flower anatomy was investigated by light microscopy to describe organ modification and to specify the timing when morphology begins to deviate. Early stages of floral development were defined in fertil ...

Abstract:
... Exotic germplasm is often used in maize (Zea mays L.) breeding programs. However, the occurrence of genotype × environment interactions (GEIs) may mask the potential utility of exotic material. Our objective was to understand better GEIs for temperate, temperate × highland, and highland tropical maize genotypes cultivated under temperate or highland tropical conditions. We related yield instabilit ...

In this study we have attempted to quantify the thermal and photoperiodical responses of rice (Oryza sativa L.) flowering time QTLs jointly by a ‘date-of-planting’ field experiment of a mapping population, and a ‘phenological model’ analysis that separately parameterizes the two responses, based on daily temperature, daily photoperiod and flowering date. For this purpose, the ‘three-stage Beta mod ...
