Sixty-four F2-derived F4 lines were produced from a cross between the semidwarf wheat (Triticum aestivum L.) cultivar CSP-44 (Condor sib, Rht1) and the tall cultivar Glenlea (rht1). Thirty-two homozygous tall lines and thirty-two homozygous short lines were tested at Saskatoon under rainfed conditions in 1982 and both rainfed and irrigated conditions in 1983. The objective was to determine the effects of the gene for demidwarfism on yield and other characters under Saskatchewan conditions. The semidwarf lines consistently had more spikes per metre of row and more kernels per spike, but a lower weight per kernel. The percent increase in the number of kernels per spike for the semidwarfs compared to the tails varied more in different environments than the change in the other two components of yield. As a result, the semidwarf lines outyielded the tall lines by 13.1% in the 1982 rainfed test and by 4.1% in the 1983 irrigated test but yielded 2.7% less in the 1983 rainfed test. In general, yield showed only low positive correlations with the yield components, while the yield components showed relatively low negative correlations among themselves.Key words: Wheat, Triticum aestivum, height, semidwarfs, yield components

The present investigation consists of   26 genotypes of Chickpea including one check, which were grown in the Field Experimentation Centre of the Department of Genetics and Plant Breeding, SHUATS, Prayagraj during Rabi 2020 following RBD with three replications. The data were recorded on 11 characters. Assessment of genetic variability, cause effect and interrelationship among yield components in chickpea. High significant variation was obtained for all characters studied. High GCV and PCV in chickpea germplasm were observed for Total no of pods per plant, number of effective pods per plant, biological yield, seed yield. High estimate of heritability coupled with high genetic advance as percent of mean was recorded for No. of primary branches, No. of secondary branches, Total no of pods per plant, No. of effective pods per plant, biological yield, Seed yield per plant, Harvest index, Seed index. High values for heritability indicates that it may be due to higher contribution of genotypic components. Traits exhibiting high heritability coupled with genetic advance as percent of mean suggest that the traits are governed by additive gene action, equal contribution of additive and non-additive gene action respectively. Correlation coefficient analysis revealed that seed yield per plant exhibited positive and significant association with Biological yield per plant, Harvest index and plant height at genotypic and phenotypic levels. Correlation coefficient analysis revealed that seed yield per plant exhibited positive and significant association with Biological yield per plant, Harvest index and plant height at genotypic and phenotypic levels. Path analysis revealed that characters plant height, number of primary branches, biological yield and harvest index have positive direct effect on seed yield per plant at genotypic and phenotypic level.

Line × tester analysis of twenty lines and three testers of Indian mustard (Brassica juncea L. Czern & Coss.) cultivars were used to estimate general combining ability (GCA), specific combining ability (SCA) effects, high parent heterosis and narrow-sense heritability estimate for plant height, yield components and seed yield. Significant variance of line x tester for the traits like pods per plant and seed yield indicating non additive genetic effects have important role for controlling these traits. Significant mean squares of parents v/s crosses which are indicating significant average heterosis were also significant for all the traits except seeds per pod. High narrow-sense heritability estimates for all the traits except seeds per pod exhibited the prime importance of additive genetic effects for these traits except seeds per pod. Most of the crosses with negative SCA effect for plant height had at least one parent with significant negative or negative GCA effect for this trait. For most of the traits except pods per plant, the efficiency of high parent heterosis effect was more than SCA effect for determining superior cross combinations.

Agronomic practices, such as planting date, seeding rate, and genotype, commonly influence hard red spring wheat (HRSW, Triticum aestivum L. emend. Thell.) production. Determining the agronomic optimum seeding rate (AOSR) of newly developed hybrids is needed as they respond to seeding rates differently from inbred cultivars. The objectives of this research were to determine the AOSR of new HRSW hybrids, how seeding rate alters their various yield components, and whether hybrids offer increased end-use quality, compared to conventional cultivars. The performance of two cultivars (inbreds) and five hybrids was evaluated in nine North Dakota environments at five seeding rates in 2019−2020. Responses to seeding rate for yield and protein yield differed among the genotypes. The AOSR ranged from 3.60 to 5.19 million seeds ha−1 and 2.22 to 3.89 million seeds ha−1 for yield and protein yield, respectively. The average AOSR for yield for the hybrids was similar to that of conventional cultivars. However, the maximum protein yield of the hybrids was achieved at 0.50 million seeds ha−1 less than that of the cultivars tested. The yield component that explained the greatest proportion of differences in yield as seeding rates varied was kernels spike−1 (r = 0.17 to 0.43). The end-use quality of the hybrids tested was not superior to that of the conventional cultivars, indicating that yield will likely be the determinant of the economic feasibility of any future released hybrids.

SummaryThe effects of crop density and fertilizer application on three varieties of marrowstem kale were investigated. The yield of stem, yield of leaf, components of leaf yield and plant height were studied separately. Varietal differences and effects of density and fertilizer application were significant for all characters, except for the effect of crop density on leaf and stem yield per ha.Significant variety x treatment interactions occurred for a number of the characters measured. The possible importance of these is discussed.

Increasing salinity caused significant reduction in plant height, root and shoot dry weight, yield and yield components, seed oil and protein contents of all cultivars. However, there were significant differences among the cultivars for measured traits for each salinity level. Based on seed oil yield data, Safiabad and Kraj at 0.0038ds.m<sup>-1</sup>, Safiabad and Ultan at 4.89ds.m<sup>-1</sup>, Ultan, Safiabad and Darab at 8.61 salinity levels were the superior cultivars. High variability in tolerance to salinity among the tested sesame cultivars suggests that selection of more salt tolerant cultivars for planting or breeding purposes is possible.</span></p><p class="emsd-body"><span lang="EN-GB">Highlights</span></p><p class="emsd-body"><span lang="EN-GB">Effects of contrasting salinity levels (0.0038 (tap water as control), 4.89, 8.61, 10.5, 14.54, 17.74 ds.m<sup>-1</sup>NaCl) on sesame cultivars were tested.

Faba bean production is a common practice in Lemu Bilbilo areas. However, faba bean productivity is affected and limited by poor soil fertility and lack of alternative technologies such as application of optimum phosphorus fertilizer for different faba bean varieties. In view of this, a field experiment was conducted on farmer’s field during the 2017 main cropping season at Lemu Bilbilo with the objectives to determine the response of faba bean varieties to different rates of P fertilizer and its influence on yield and yield components of faba bean varieties.  The treatments include three faba bean varieties (Tumsa, Gebelcho and Dosha) and five phosphorus levels (0, 10, 20, 30 and 40 kg P ha-1) from Triple Super Phosphate. The experiment was laid out in a randomized complete blocked design with 3 x 5 factorial arrangements with three replications. Significantly (P<0 .05) higher plant height was recorded from Tumsa variety. Total productive tillers per plant, thousand seed weights, and harvest index and biomass yield of faba bean were significantly affected by main effect of varieties. Higher total productive tillers per plant (1.53) were obtained from application of 30 kg P ha-1. Higher plant height (153 cm), biomass yield (14158 kg ha-1) and grain yield (6323 kg ha-1) were obtained from application of 40 kg P ha-1. Application of 10, 20 and 30 kg P ha-1 gave marginal rate of return of 1404694 and 502% for faba bean production, which are well above the minimum acceptable rate of return. Therefore, application of 20 kg ha-1 of P with Tumsa, Gebelcho and Dosha faba bean varieties were proved to be productive and superior both in seed yield as well as economic advantage and recommended for faba bean production in Lemu Bilbilo area. Further study should be conducted in the future both over locations and years in order to give full recommendation for practical application.
