High Quality Seed

One of the leading grain crops in Russia is spring wheat. This is a strategic food crop of our country; it is also an important component in the structure of forage crops for monogastric animals, such as pigs and poultry. The purpose of the research was to evaluate spring soft wheat varieties of different maturity groups in order to identify genotypes as the starting material for obtaining varieties adapted to the cultivation zones, and to determine the areas optimal for the production of grain for seed purposes with high quality indicators. Field studies have been carried out in three ecologically different zones: the Priobskaya zone, the Prialtaiskaya zone, and the Prisalairskaya zone. Under the conditions of the Altai Territory, genetic sources of spring soft wheat have been identifi ed for different soil and climatic parameters of the study zones, the use of which will allow obtaining high-yielding varieties with high quality grain for specific cultivation conditions. The variability of the indicators of the characteristics of varieties in three ecologically different zones has been determined. The indicators of adaptability and stability of spring soft wheat varieties in different zones of cultivation have been determined. The optimal zones for conducting breeding work and seed production of varieties have been identifi ed. New scientific data on the quality parameters of seed grain in various agro-climatic zones of the Altai Territory have been obtained. The share of the contribution of the factors “variety”, “year”, “environment” to the variability of grain quality characteristics has been established. The economic efficiency of cultivating varieties of spring soft wheat for the production of high-quality seed grain has been determined.

Australian Wheat

This handbook provides a practical description of wheat grain, heads and plants at several growth stages. It is designed to assist in distinguishing varieties currently grown throughout Australia, in the regions where each is usually grown. It is directed at a broad audience, including those involved with the grain trade at all stages, from seed production, through growing and harvesting, to receival and segregation, sales and utilization. Although Australia-wide in its overall approach, it is hoped that the handbook will form a basis to meet specialised local needs. Thus smaller sets of sheets, relating to local groups of varieties, might be selected and additional comments added, in the space provided, relating to the particular locality and season. In such a case, the characters that show the greatest differences between the particular varieties should be selected for identification.

Lodgepole pine is an exotic with impressive growth potential in northern and central Sweden. In recent years this species has gained a wide acceptance for use in reforestation and Swedish authorities have therefore embarked on a significant tree improvement and seed production program to meet future demands for high quality seed. The initial phase of this program, a recently completed parent tree selection project in western Canada, is described in this paper. Subsequent plans for genetic testing and seed production in Sweden are also addressed.

New tropical pumpkin (Cucurbita moschata Duchesne) genotypes were evaluated for yield, flesh (mesocarp) color, pest resistance and seed production as compared with the standard cultivar Soler in six field trials at three Puerto Rico locations during a two-year period (2003-2005). Genotypes included an open-pollinated population (PRShortvine-1) and four lines (E0305-1, E0305-2, E0305-3 and E0305-4) with a semi-bush growth habit, as well as a new long-vine open-pollinated population (PRLongvineSLR). Various within-row (0.9- and 1.9-m) and between-row (1.9- and 3.8-m) planting distances were tested. Not all genotypes nor planting distances were included in each trial. PRLongvineSLR was partially resistant to the melonworm (Diaphania hyalinata), whereas lines E0305-1 and E0305-2 were very susceptible. These same lines, as well as PRShortvine-1, were also susceptible to downy mildew, Pseudoperonospora cubensis. All genotypes produced similar yields. Within-row planting distance generally had no effect on fruit weight, fruit number and yield. All new genotypes had good flesh thickness (>4 cm) and small fruit cavities. Flesh color of PRShortvine-1 and PRLongvineSLR tended to be more orange than that of Soler. Lines E0305-3 and E0305-4 had poor seed production, whereas seed production in fruits of PRShortvine-1 and PRLongvineSLR was similar to that of Soler. Despite some shortcomings, PRShortvine-1 and PRLongvineSLR are two advanced open-pollinated populations that should be considered for formal release on the basis of their field performance, good fruit quality and ability to produce profitable amounts of seed in a seed production program.

Seed Supply

The seed replacement rate of major field crops is very low, about 8%, in Nepal with 92% seed supply of major field crops from informal sector. Different seed production initiatives are undertaken by public and private sectors. However, their role and effectiveness on seed sector development have not been assessed. A review on secondary data related to seed production and usage and primary data collected from different public and private organizations in the year 2011were used to assess the role of District Level Seed Self Sufficiency Program and Community Based Seed Production program on current seed supply situation in Nepal. DISSPRO is the most popular, widely adopted and cheapest seed producing program with annual production of 40.4% followed by CBSP 3.83% of the total certified/improved seeds in the country. The seed production trend of DISSPRO and CBSP is rapidly increasing. Strengthening seed sector through the integration of DISSPRO, CBSP and other seed initiatives together with effective enforcement of seed regulation for quality seed multiplication, distribution and use is necessary for rapid rise on SRR, enhancing crop production and food security in Nepal.

The Cost

Hybrid varieties can provide the boost needed to increase stagnant wheat yields through heterosis. The lack of an efficient hybridization system, which can lower the cost of goods of hybrid seed production, has been a major impediment to commercialization of hybrid wheat varieties. In this review, we discuss the progress made in characterization of nuclear genetic male sterility (NGMS) in wheat and its advantages over two widely referenced hybridization systems, i.e., chemical hybridizing agents (CHAs) and cytoplasmic male sterility (CMS). We have characterized four wheat genes, i.e., Ms1, Ms5, TaMs26 and TaMs45, that sporophytically contribute to male fertility and yield recessive male sterility when mutated. While Ms1 and Ms5 are Triticeae specific genes, analysis of TaMs26 and TaMs45 demonstrated conservation of function across plant species. The main features of each of these genes is discussed with respect to the functional contribution of three sub-genomes and requirements for complementation of their respective mutants. Three seed production systems based on three genes, MS1, TaMS26 and TaMS45, were developed and a proof of concept was demonstrated for each system. The Tams26 and ms1 mutants were maintained through a TDNA cassette in a Seed Production Technology-like system, whereas Tams45 male sterility was maintained through creation of a telosome addition line. These genes represent different options for hybridization systems utilizing NGMS in wheat, which can potentially be utilized for commercial-scale hybrid seed production.

The study was undertaken to find out variety wise adoption rate of wheat in Bangladesh through expert elicitation procedure. Many varieties have been developed by Wheat Research Centre (WRC) but in details of varietal information and adoption information database was not developed which is very important and valuable for the scientist and policy planner. This study through expert elicitation for constructing detail varietal development and adoption database is timely and necessary for the research institute. From all over the Bangladesh 14 experts was invited to share their valuable knowledge and experience on wheat cultivation and adoption in the country. The average age of the experts were 54 yrs and average experience on wheat adoption was 22.65 yrs. The wheat expert informed that 13 major varieties are adopted by the farmers in the recent year(2013-14). Among those varieties, BARI Gom 24 (Prodip) covered highest cultivated area (186026 ha) which shared 41.03% of total wheat cultivated area. BARI Gom 21 (Shatabdi), BARI Gom 26 and BARI Gom 23 (Bijoy) ranked 2nd, 3rd and 4th position according to the share of cultivated area covered. The seed production information showed that BADC the only wheat seed producer supplied 24912.60 mt of wheat seed in the year 2013-14. The trend of seed production by different wheat variety revealed that over the period 2010-14, the seed production of BARI Gom 24 (Prodip) increased and BARI Gom 21 (Shatabdi) decreased. Increased seed production trend of Prodip variety leaded to highest adopted area of that variety. The main reason behind highest adopted area of Prodip variety was it’s very attractive attributes like high yield, big spike, large grain and lodging tolerance character. Although the Prodip covered highest area but other newly developed variety like BARI Gom 25, BARI Gom 26, BARI Gom 27 and BARI Gom 28 were the most promising varieties which showed increasing adoption path among the expert. These varieties have very good potentiality due to having short duration, tolerance to terminal heat stress, tolerant to salinity and lodging attributes. Satisfying higher demand for wheat consumption and ensuring food security through providing alternative to rice are the major concerning issue of the policy planner and the scientist. Therefore, the study have been undertaken to fulfill this issues.Bangladesh J. Agril. Res. 41(3): 491-505, September 2016
