This book was released on 1973 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic differences, extent of hybrid vigor, nature of gene action, heritability estimates, and associations among characteristics, and between progenies and their respective mid-parents were determined for seed and plant characteristics in white clover (Trifolium repens L.). Ten seed and seedling vigor characteristics, including seed weight, ATP content in seed, seed respiration, and seedling vigor index were studied for a diallel cross consisting of 28 single crosses, five test-crosses, four checks, and eight open-pollinated seed and seedlings. Twenty-three plant characteristics on stolon, petiole, leaf, and forage were examined on the eight clones diallel cross, five test-crosses, three checks, the eight parental clones of single crosses, and six parent clones of the test-crosses. These 14 parent clones for this study were assembled on the basis of diverse morphology and origin. Most seed and seedling vigor characteristics, except RQ values, and most plant characteristics, except internode length, LAR and diurnal ratio in SLW, expressed significant differences among and within most groups of progenies and parental clones. All seed and seedling vigor characteristics, except RQ values, responded primarily to the nonadditive type of gene action. This suggests that the plant breeder should design his breeding program to develop varieties where hybrid vigor can be used to advantage. Among the criteria used in this study to measure seed and seedling vigor, ATP content per seed was closely associated with seedling vigor index and with certain plant characteristics, including forage yield per plant. The associations of seed weight with other seed and seedling vigor characteristics were negative or poor. Most plant characteristics showed apparent hybrid vigor when progenies were compared with their respective mid-parents. With few exceptions, most plant characteristics, stolon, petiole, leaf and forage yield per plant, responded primarily to the nonadditive gene system. This indicated that the plant breeder may use the hybrid approach to white clover variety development. The exceptions were leaf ratio and SLW which responded primarily to additive gene action, and area and dry weight per leaf appeared to respond equally to additive and nonadditive gene action. Genetic differences were more readily identified for stolon number and length when measurements were taken after 70 days of growth. Yield components, such as number, length, and diameter of stolon, petiole length, number of leaves per plant, and dry weight per leaf were closely related to each other. The leaf components of yield, dry weight per leaf and number of leaves per plant, had the highest direct and indirect effects on forage yields per plant among the yield components. This study showed nonadditive gene action primarily responsible for most seed and plant characteristics. Considering the ease of vegetative propagation in this species along with the self-incompatibility, mechanisms, it is suggested that parent geneotypes may be developed by some recurrent selection procedure, then crossed on a two clone synthetic basis to form experimental lines for testing purposes.

Available in PDF, EPUB and Kindle. Book excerpt: Red clover (Trifolium pratense L.) is one of the many species belonging to the genus Trifolium, which are widely cultivated around the world. It is a perennial plant and offers permanence that determines its uses as well as environmental and agronomic requirements. Red clover is grown mainly for seeds and biomass. The most important environmental factors that affect red clover yield are soil conditions, temperature and precipitation during the growing season. Key agronomic factors include sowing date, cultivation regime, fertilization, plant protection and harvesting date. The species can be grown in pure and mixed stands (with alfalfa, cereals and various grass species). Newly bred triploid varieties of red clover are characterized by desirable growth habit traits and yield components as well as high yield. Red clover has many applications. It is currently experiencing a revival of interest as a traditional folk remedy. The species acts as a rich source of compounds with expectorant, analgesic and antiseptic properties. The callus from Trifolium pratense has been found to exert inhibitory effects on fungal and bacterial strains. Red clover contains isoflavones, anthocyanin pigments and phytoestrogens, which may help reduce the risk of heart disease, breast cancer and endometrial cancer; it also alleviates menopausal symptoms. Red clover lowers blood cholesterol levels and helps prevent prostate cancer. Red clover ointments are used to treat skin diseases, including psoriasis. Red clover provides biomass for livestock nutrition and/or biogas production. It has high nutritional value and constitutes valuable raw material for silage making. Red clover can be grown with grasses, barley, oats and wheat, thus providing various types of fodder with high biological value and natural high-protein feed. When grown as a cover crop, red clover fixes and supplies nitrogen to cereal crops. It also helps break disease and insect cycles, especially in plantations protected against weeds. The crude protein content of red clover decreases with advancing maturity. Due to its permanence, this perennial plant contributes to environmental protection and anesthetization; it helps prevent soil erosion, and is used in phytoremediation and barren land management schemes.

This book was released on 1992 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The objective of this study was to evaluate the short-term (one-year) biomass production in red clover and to obtain an estimate of the heritability of this characteristic. Progenies from parents with high biomass had higher biomass than those from parents with low biomass or having one parent in each category. The narrow-sense heritability estimated from mid-parent offspring regression was 0.23, from parent-offspring correlation was 0.22, and realized heritability was 0.15, indicating that progeny testing would be required for successful selection of populations with greater biomass production. Plants selected for high biomass production tended to have higher shoot:root ratios and flower more profusely than the parental checks and the low biomass plants. This indicates that by selecting for high biomass, red clover will be selected for more annual growth habit at the same time." --
