ชื่อเรื่อง (EN): Potential Evaluation of Soybean Promising Lines of Kasetsart University for the Central Area
บทคัดย่อ: The evaluation of yield and development of soybean elite lines for the central area was conducted through the multi-environmental yield trial. Six elite lines from the Soybean and Mungbean Breeding Project of Kasetsart University and the 2 recommended cultivars (CM60 and NS1) were grown at 2 sites (Kampaeng Saen, Nakhon Pathom and Lopburi research station, Lopburi) in dry and late rainy season during the year 2008-2011. A total of 16 trials (environments) using the RCBD with 3 replicates were obtained. The anlyses and estimation of the effects of genotype, environment and genotype x environment interaction were carried out by using the statistic technique of the additive main effect and multiplicative interaction (AMMI). The results showed that AMMI model could effectively separate a large proportion from the total variation. The sum square percentage (%SS) of seed yield, number of seeds per plant, number of seeds per pod, 100-seeds weight, days to 50% flowering, days to harvest, number of leaves on main stem at harvest and plant height at harvest were 98.33, 99.84, 99.53, 99.34, 99.89, 99.92, 99.18 ND 99.48%, respectively. KUSL3802-1 was the best adapted line with the highest averall site mean of 259.88 kg/rai followed by KUSL20004 (243.65 kg/rai) ST2 34-1 (237.14 kg/rai) and NS1 1-12 (231.62 kg/rai) which were higher than the 2 recommended cultivars CM60 (220.04 kg/rai) and NS1 (223.20 kg/rai). Consideration of the estimated regression coefficients (slope, b’) of yield of each elite lines with all environments, KUSL3802-1, NS1 1-12 and KUSL20004 were well stable with the b’ equal to 0.966, 1.044 and 1.011, respectively. Whilst, KUSL3802-4, ST2 34-1 and KUSL3802-6 were also rather stable with the b’ equal to 0.997, 1.020 and 0.947, respectively. When considered together with yield components and other developmental characters, KUSL3802-1, ST2 34-1, KUSL20004 and NS1 1-12 were the 3 elite lines that having good adatability, stability and yield and development potential, respectively. Slightly lower stability due to the apparent genotype x environment interaction were, however, noticed for KUSL3802-1 and KUSL20004 in number of pods per plant, ST2 34-1 in days to harvest, and NS1 1-12 in number of pods per plant and number of leaves on main stem per plant.Elite soybean lines from the breeding program may have different canopy architecture resulted in different management for greater yield. Therefore, the experiments were conducted to test the acclimatization of promising soybean lines to cultural practices. The test was carried out at the National Corn and Sorghum Research Center and Lop Buri Research Station, Insee Chandrastitya Institute for Crop Research and Development, during October 2007 – September 2011. A split plot in RCBD was used with 3 replications. In each year, there were 2 experiments. Experiment 1 involved the effects of plant spacings in which the main plots were 10 and 20 cm plant spacings. Experiment 2 studied the effects of numbers of plant per hill in which the main plots were 2 and 3 plants per hill. In both experiments, the sub plots were 8 soybean lines (SJ5 and CM 60 as check varieties, and KUSL3802-6 , KUSL3802-4 KUSL3802-1 NW1. 1-12 ST2. 34-1 and KUSL20004). There were 4 rows of 5-m long in a subplot. Land was plowed twice and harrowed and compound fertilizer (15-15-15) was applied at the rate of 50 kg/rai. Weeds were pre-emergent controlled using imazethapyr, Additional weeding simultaneously with earthened – up the rows was done at 35 days after planting. Throughout 4 years of the project, it was concluded that in the central area where irrigation is available in the dry season, it was recommended that soybean be planted using 10-cm plant spacing and 2 – 3 plants pre hill. The recommended soybean elite lines were KUSL 3802-1, KUSL3802-4 and KUSL20004. For the rainy season, it was recommended that soybean be planted using 20-cm plant spacing and 2-3 plants per hill and using the elite lines recommended above. Seed quality is an important constraint in soybean breeding program especially in hot-humid regions. Before releasing a soybean variety, its potential in producing good quality seed must be tested. Seed germination, vigor and storability are basic characteristics need to be assessed. Six advanced breeding lines of soybean, i.e. KUSL3802-1, KUSL3802-4, KUSL3802-6, NS1 1-12, ST2 34-1 and KUSL20004 under Kasetsart University Soybean Research Project were evaluated comparing to 2 recommended cultivars, i.e. SJ5 and CM60. The results revealed that seed quality of KUSL3802-6 was relatively high and quite stable throughout the series of experiments, KUSL3802-1, NS1 1-12 and KUSL3802-4 showed good seed quality although they varied in some experiments. However, seed quality of all advanced breeding lines, including ST2 34-1 and KUSL20004 was acceptable comparing to that of Chiang Mai 60. For soaking injury study and the response of advanced soybean lines to pure neem oil at the rate of 8 ml/kg seed, it was found that different soybean lines responded differently to soaking injury. KUSL20004 and KUSL3802-4 was quite susceptible to soaking injury comparing to other lines. Neem oil seemed to slow the rate of seed deterioration during storage and reduced the severity of soaking injury resulting in a higher germination both under normal and soaking conditions of seed after a period of storage. Studies on physical characteristics of seed coat and seed quality revealed that KUSL3802-1 showed the highest values of percent seed coat, seed coat thickness and specific weight of seed coat with relatively good seed quality when compared with those of SJ5, while ST2 34-1 and KUSL20004 tended to have low to medium values of seed coat measurements with low seed quality. It can be said that seed with thick seed coat relatively shows high vigor. For the study of seed coat under electron microscope, it was found that there was no relationships between pore size and pore number and seed quality, but there was a tendency that pore size was negatively correlated with germination and vigor. For a series of experiments during 4 years of study, it can be concluded that all the 6 advanced soybean lines of Kasetsart University showed a reasonably acceptable seed quality comparing to Chiang Mai 60 which is a recommended cultivar with relatively low in seed quality. However, KUSL3802-6 was consistently high in seed quality, while KUSL3802-1, NS1 1-12 and KUSL3802-4 showed good seed quality although the performance sometimes varied from season to season.On-farm testing had very important for plant breeding. The objective of this study was to compare between 6 elite soybean lines (KUSL 3802-1, KUSL 3802-4, KUSL 3802-6, KUSL 20004,NS 1 1-12 and ST 2 34-1) from Kasetsart University and 3 checks soybean cultivars (CM60 SJ.5 and NS.1) from Department of Agriculture in the 3 farmer field: 2 fields at Sakeao province in dry season 2011 (lowland and upland) and 1 field at Saraburi in rainy season 2012 (upland) . Soybean promising lines and checks were evaluated in experiments The result from evaluation in the upland at Sakeao province indicated that the KUSL20004 had the most average yield and KUSL3802-1 had the second average yield . As for testing in the lowland couldn't collect data.While the result from evaluation in the upland at Saraburi province indicated that the KUSL3802-1 had the most average yield and the most average satisfaction rating of the farmersThe studies on physiological and developmental characteristics of soybean promising lines on productivity were conducted in field experiment at Kamphangsan Campus, Kasetsart University. Seven promising lines of ST.2 34-1, NS 1 4-6, KUSL3802-1, KUSL 3802-6, KUSL 20004, KUSL 3802-4, NS.1 1-12 and three standard varieties of CM 60, Chakkrabhandhu 1 and ST 2 were employed in late rainy season and dry season. Randomized Complete Block Design (RCB) with 3 replicates were used. The results showed that these promising lines differed in their phasic development which the vegetative phase were about 28-40 days and 26-32 days after planting while reproductive phases were about 29-98 days and 26-89 days under late rainy season and dry season, respectively. The early and late promising lines when planted in both seasons were KUSL 20004 and KUSL 3802-1 while.the intermediate promising line were KUSL 3802-6 and ST 2 34-1. The physiological characteristics, yield production and yield components were significantly different in both among promising lines and sowing dates. The lines of KUSL 3802-1 and NS 1 4-6 gave the highest in leaf area index at R5 and R6 stage. For chlorophyll content in leaf (SPAD unit), there were differences among promising lines and sowing dates only at R3 stage. The promising lines of KUSL 3802-1 and ST 2 34-1 gave the highest yield about 332.9 and 319.6 kg per rai, respectively under late rainy season while NS 1 4-6 and NS 1 1-12 gave the highest yield about 332.9 และ 319.6 kg per rai, respectively under dry season. Correlation coefficients among physiological characteristics and yield components with yield were investigated. It was found that leaf area index, number of pods per plant, number of seeds per plant and 100 seed weight were positively correlated with seed yield. Whilst, chlorophyll content in leaf (SPAD unit), stomata density and stomata index were not correlated with seed yield. For high temperature response, the results indicated that the promising line NS 1 1-12 could be grown and developed under the conditions of temperature 38/26 0C (day/night) as MDA content lower about 6.7 nanomole per gm fresh weight while KUSL 3802-1, KUSL 3802-4 and NS 1 4-6 had MDA content 6.7 nanomole pe gm fresh weight under temperature 34/26 0C (day/night).
