“…One gene (A) is dominant for hardseededness, a second gene (B) is dominant for softseededness when the A locus is homozygous recessive (aa), while the double recessive genotype (aabb) is hardseeded. In Lupinus hispanicus (Arrieta et al 1994), Lupinus angustifolius (Forbes and Wells 1968), and Lupinus luteus (Mikolajczyk 1966), seed-coat permeability is controlled by one recessive gene. However, Serrato-Valenti et al (1989) found that in Lupinus angustifolius, where the micropyle is the port of water entry in soft seeds, permeability is controlled by two genes.…”

The field of plant breeding covers a broad range of different species and categories of plants. While there are many techniques and issues that are similar across these species, many more are unique to each genus.The Handbook of Plant Breeding is organized by major crop categories and includes the most up-to-date molecular techniques being used. It will serve as a resource for plant breeding laboratories in both the university and industrial setting.More information about this series at

“…In forage lupins ( Lupinus spp. ), for instance, a recessive allele has been identified which results in 100% permeable seed proportions at maturity (Arrieta et al , 1994; Boersma et al , 2007). Permeable-seeded lines are also known for Lens (Ladizinsky, 1985), Vicia (Ramsay, 1997) and Ornithopus (Taylor, 2005) but, to our knowledge, not for Trifolium .…”

The incidence, field performance and heritability of non-dormant seeds in white clover (Trifolium repensL.)

The incidence, field performance and heritability of non-dormant seeds in white clover AbstractMature seeds of many legume species are normally characterized by water-impermeable seed coats, a form of physical dormancy. However, observations have suggested that the incidence of mature but permeable (non-dormant) seeds is sometimes substantial. Yet, the ecological processes associated with this non-dormancy have received little attention by plant ecologists. In white clover (Trifolium repens), we therefore studied (i) the occurrence of initially permeable seeds in wild populations, (ii) the relative performance of non-dormant and dormant seeds in plant establishment and reproduction in a field-sown experiment, and (iii) the extent to which the trait is affected by humidity and plant genotype in a greenhouse experiment. No less than 35% of all viable seeds from the wild populations proved to be water-permeable at maturity. The proportion of permeable seeds within inflorescences ranged from 0 to 100%. In the field-sown experiment, autumn-germinated nondormant seeds had almost equally good chances of establishing as spring-germinated dormant seeds. Due to a marked head start in growth, the former yielded more flowers (and thus seeds) in the first flowering season. However, the greenhouse experiment proved that variation in the proportion of permeable seed between inflorescences represented a plastic response to humidity conditions during seed ripening, rather than variation among clones (broad-sense heritability = 0.025). Thus the trait is not easily subject to selection.

<p>El presente trabajo presenta el panorama y describe el desarrollo de las reflexiones y diagnósticos del pensamiento social y las ciencias sociales sobre y desde el estado de Tabasco; y las condiciones del entorno social local en el que se practican. En el trabajo se demuestra que la producción de este tipo de trabajos es perfectamente acorde a los momentos de crisis y por su tipo refleja perfectamente los momentos de continuidad y ruptura en la historia del estado a pesar de un entorno sociocultural poco propicio. Así, por ejemplo, las ciencias sociales son subsumidas a un papel de mera contabilidad social, legitimación y promoción durante el período del desarrollismo económico (1953-1970) caracterizado por la construcción de grandes obras de infraestructura y planes de desarrollo agropecuario territorial, o durante la expansión de las obras de exploración y explotación petrolera; pero son llamadas a encontrar explicaciones y alternativas cuando la población regional reacciona contra los excesos y resultados no deseados de tales desarrollos, como ocurre con la resistencia contra el Plan Chontalpa y posteriormente con la resistencia contra los impactos de la industria petrolera. En el momento de mayor auge económico petrolero y su crisis, se hace un esfuerzo por implantar localmente la enseñanza y la investigación de dichas disciplinas, a la vez que ofrecen un discurso alternativo de desarrollo endógeno. Posteriormente, a partir de mediados de la década de los 90 llama la atención que la planeación se realiza a nivel macroregional y los trabajos locales pasan de depender de proyectos institucionales a iniciativas personales de funcionarios locales que dan los espacios o promueven las investigaciones y publicaciones.</p>
