Book Adaptation of Indian Mustard Brassica Juncea L to Short Season Dryland Mediterranean type Environments

Download or read book Adaptation of Indian Mustard Brassica Juncea L to Short Season Dryland Mediterranean type Environments written by Chandra Padmini Gunasekera and published by . This book was released on 2003 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seed yield, oil and protein concentrations were measured at all three sites and detailed measurements of phenology, morphology, dry matter production and partitioning, radiation absorption, seed yield and its components, and seed oil and protein concentrations were taken only at Merredin. The effects of post-flowering soil moisture stress on mustard and canola was studied in detail using rainout shelters at Merredin in the 2001 growing season. Measurements of water use, leaf water potential, osmotic potential, osmotic adjustment, relative water content, and leaf diffusive conductance were taken together with morphology, dry matter production and partitioning, radiation absorption, seed yield and its components, and seed oil and protein concentration. Mustard produced seed yields similar to canola at a medium rainfall site at Northam in south Western Australia. Early sowing (May) was more suitable for mid and late maturing genotypes and mid sowing (early June) was optimum for early maturing genotypes at this site. Dry matter production and seed yield was highest in early sowing due to balanced pre-anthesis and post-anthesis development of the crop and its ability to avoid terminal drought. Very late sowing (after July) significantly reduced the dry matter production, seed yield and oil concentration of mustard and canola due to poor establishment, reduced post-anthesis duration, soil moisture and high temperature stresses which occurred at the end of the season. Mustard did not produce significantly higher dry matter and seed yield compared to canola at the medium rainfall site, Northam. Seed yield and oil concentration of mustard and canola in low rainfall environments (Merredin, Mullcwa and Newdegate) were higher when sown early in the season (May). Longer growing duration and post-anthesis duration were favourable for higher yields. the break o.

Book Brassica Improvement

Download or read book Brassica Improvement written by Shabir Hussain Wani and published by Springer Nature. This book was released on 2020-03-13 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global population is mounting at an alarming stride to surpass 9.3 billion by 2050, whereas simultaneously the agricultural productivity is gravely affected by climate changes resulting in increased biotic and abiotic stresses. The genus Brassica belongs to the mustard family whose members are known as cruciferous vegetables, cabbages or mustard plants. Rapeseed-mustard is world’s third most important source of edible oil after soybean and oil palm. It has worldwide acceptance owing to its rare combination of health promoting factors. It has very low levels of saturated fatty acids which make it the healthiest edible oil that is commonly available. Apart from this, it is rich in antioxidants by virtue of tocopherols and phytosterols presence in the oil. The high omega 3 content reduces the risk of atherosclerosis/heart attack. Conventional breeding methods have met with limited success in Brassica because yield and stress resilience are polygenic traits and are greatly influenced by environment. Therefore, it is imperative to accelerate the efforts to unravel the biochemical, physiological and molecular mechanisms underlying yield, quality and tolerance towards biotic and abiotic stresses in Brassica. To exploit its fullest potential, systematic efforts are needed to unlock the genetic information for new germplasms that tolerate initial and terminal state heat coupled with moisture stress. For instance, wild relatives may be exploited in developing introgressed and resynthesized lines with desirable attributes. Exploitation of heterosis is another important area which can be achieved by introducing transgenics to raise stable CMS lines. Doubled haploid breeding and marker assisted selection should be employed along with conventional breeding. Breeding programmes aim at enhancing resource use efficiency, especially nutrient and water as well as adoption to aberrant environmental changes should also be considered. Biotechnological interventions are essential for altering the biosynthetic pathways for developing high oleic and low linolenic lines. Accordingly, tools such as microspore and ovule culture, embryo rescue, isolation of trait specific genes especially for aphid, Sclerotinia and alternaria blight resistance, etc. along with identification of potential lines based on genetic diversity can assist ongoing breeding programmes. In this book, we highlight the recent molecular, genetic and genomic interventions made to achieve crop improvement in terms of yield increase, quality and stress tolerance in Brassica, with a special emphasis in Rapeseed-mustard.
