<p>An evaluation of the agronomic performance of two lupin species (<em>Lupinus albus</em> and <em>Lupinus luteus</em>) was conducted at the Institute of Forage Crops (Bulgaria) during 2012-2014. The hightest positive correlations among the agronomic traits in white lupin were between number of pods per plant and seed weight per plant (r = 0.956); plant height with pod stem length (r = 0.935) and pod length (r = 0.934); seed weight per plant and number of pods per plant (r = 0.956). In yellow lupin relatively high phenotypic correlations were detected between number of pods per plant and seed weight per plant (r = 0.956); seed weight per plant and number of pods (r = 0.875) and number of seeds per plant (r = 0.927). Collecting data on the mutual relationships among individual yield components and their effect on the yield remains crucial for their optimisation and development of improved lupin genotypes with high quality and stable yields. Based on the trait associations it can be concluded that lupin breeders should pay attention to the traits such as pod length, number of seeds per plant and 1000 seeds mass when selecting high-yielding genotypes.</p>

Forty-three candidate restorer lines of Brassica napus were evaluated for 11 agronomic traits for genetic variability and interrelationships among yield traits to find out yield contributing traits. A wide range of variability and character association was observed among the lines. The line BNR-017 took the lowest time for first (26.67 days) and 100% flowering (41.00 days) whereas BNR-031 (74.33 days) and BNR-034 (74.00 days) matured earlier. The lines BNR-022 (1.07m) and BNR-026 (1.02m) were found with the shortest plant stature and all other lines were in average plant height of around 1.35m. The lines BNR-039, BNR-011, BNR-001, BNR-013 and BNR-014 were found the best performer for number of pods per plant, seeds per pod and seed yield per plant. Estimates of genotypic and phenotypic coefficient of variation were high (≥30%) for seed yield per plant (30.52 and 33.13, respectively). High broad sense heritability was recorded for 1000-seed weight (97.69%), days to ripening (97.12%), days to first flowering (96.80%), days to 100% flowering (95.50%) and pod length (92.74%). Significant and negative correlation was observed between seed yield per plant and number of seeds per pod, -0.217* and -0.192*, respectively both at genotypic and phenotypic level, while the highest positive and significant genotypic (0.786**) and phenotypic (0.795**) correlation were found with pod length. Path co-efficient analysis showed the highest positive and direct phenotypic effect of number of seeds per pod (1.221) on seed yield per plant while days to first flowering had the maximum negative direct effect (-0.039). The results of genotypic and phenotypic coefficient of variation, heritability and genetic advance in percent of mean, correlation co-efficient and path coefficient revealed that pods per plant, pod length, seeds per pod and 1000-seed weight could be used as selection criteria to increase seed yield in rapeseed.

The study was conducted in 2014-2016 on the experimental field of the Institute of Forage Crops, Pleven, Bulgaria. Aboveground and root biomass plant material of seven white lupin (Lupinus albus L.) varieties different originated was analyzed in two phenological stages. Plants were analyzed for height, fresh weight, number of leaves, nodule number and nodule weight in the beginning of flowering stage, and for number of pods, number of seeds and seed weight in the technical maturity stage. Degree of earliness of varieties was assessing as well. The group of ultra early varieties can be defined PI533704 and Zuter varieties with coefficient of earliness 1.00, to early - PI368911, PI457938 and KALI (coefficient of earliness 1.25), and to late Lucky801 and PI457923 (coefficient of earliness >1.66). A strong positive correlation was found between the seed productivity with number of seeds per plant (r=0.943) and plant height (r=0.765); close relationship of fresh aboveground mass weight with plant height (r=0.822), number of leaves (r=0.965) and fresh root mass weight (r=0.876). The varieties of interest for breeding were selected by different signs. It was concluded that the number and weight of nodules as well fresh root mass weight can be used as selection criteria for creating varieties with a higher symbiotic nitrogen fixation potential.

SUMMARYThe pollination requirements of the white lupin cultivar Vladimir were investigated in a glasshouse. Five treatments were compared in which the flowers of each plant were (i) left to autopollinate, (ii) shaken, (iii) tripped, (iv) self pollinated or (v) cross pollinated. Pollination treatments had no effect on the numbers of flowers, pods or seeds or weight of seed produced by the plants but did slightly shorten the duration of flowering, the effect being greatest when flowers were tripped or cross pollinated and least when they were shaken or self pollinated.The proportion of flowers that developed into pods differed with raceme, with secondaries producing more than tertiaries > primaries > quaternaries; the number of seeds per pod differed in the same order, but mean single-seed weight decreased on successive racemes. However, pollination treatments had no effect on the distribution of flowers, pods or seeds on the plant.This crop species is clearly highly self fertile and self pollinating and likely to yield well without insect pollination.

The study of the effect of three well known mutagens, ethyl methane sulphonate (EMS), methyl methane sulphonate (MMS) and gamma rays (GR) on the yield contributing traits of the urdbean variety TPU-4 were carried out in the M3 generation. Effect of selected mutagenic treatments/doses of EMS (0.02, 0.03 and 0.04 M), MMS (0.0025, 0.05 and 0.01 M) and (GR) (30, 40 and 50 KR) on different yield contributing traits like plant height, plant spread, number of pods per plant, pod length, number of seeds per pod, seed yield per plant and 100 seed weight were analyzed in the M3 populations of the variety TPU-4. Seeds of M2 plants and control were harvested separately and sown to raise M3 population.. Genetic variabilty in the mutagen administered M3 progeny of the urdbean variety TPU-4 was analyzed by employing statistical methods. Data on mean values and shift in the mean of seven quantitative traits was evaluated on individual plant basis. The experimental findings revealed that concentrations / dose of the all these mutagens showed inhibitory effect on plant height, number of pods per plant, pod length and number of seeds per pod. Lower concentrations of mutagens exerted a promotory effect on plant spread, 100 seed weight and seed yield per plant while higher concentrations of these mutagens inhibited them to different extent.

Background. The problem of a deficit in vegetable protein and the need to diversify agricultural produce require involvement of new and little-known crops, such as cowpea, in the production. Cowpea (Vigna unguiculata (L.) Walp.) is a high-protein leguminous crop; its breeding and production have been intensified in Russia only in recent years. The study of the VIR collection, carried out at the Institute’s branch in Astrakhan, makes it possible to disclose the crop’s breeding potential. Objective: Studying the range of variability and tracing the relationships of economically valuable traits in vegetable (green pod) cowpea under the conditions of Astrakhan Province.Materials and methods. In 2008‑2010, a study was implemented at an experiment plot of the Astrakhan branch of VIR. Thirty- three accessions of green pod cowpea from the VIR collection were studied to analyze the variability of 12 phenotypic traits. Positive and negative correlations were identified between the following characters: interphase periods (flowering, industrial ripeness and seed maturation), shape of the shrub, lengths of the stem and to the first pod, length and weight of the pod, number of seeds per pod, presence of a parchment layer and fiber in pod valves, pod yield per plant, number of pods and peduncles, seed weight per plant, and weight of 1000 seeds.Results and conclusion. Medium variability was observed for such characters as the interphase periods ‘shoots–industrial ripeness’ and ‘shoots– seed maturation’, number of seeds per pod, and weight of 1000 seeds: the coefficient of variation (CV) was 15‑18%. High variation was registered for the length and weight of the pod (CV = 26‑32%), shrub shape, stem length, and length of the stem up to the first pod (CV = 35‑37%). The widest ranges of variability were demonstrated in the quantitative yield characters of cowpea accessions: number of pods per plant (CV = 33‑49%), number of flower stalks (CV = 38‑51%), and seed weight per plant (CV = 38‑44%), which means that cowpea yield is quite susceptible to weather conditions. During the three years of studying, the lowest levels of variability in economically valuable traits were characteristic of the accessions of the early-ripening group: k‑668 and k‑873 (China); mid- ripening group: k‑971 (India); and late-ripening group: k‑141 (China). Cowpea pod productivity depended to the greatest degree from mean values of the number of pods per plant (r = 0,73) and the number of peduncles (r = 0,71). The identified correlations in the productivity components make it possible to optimize the selection of accessions promising as source materials for the development of new high-yielding cultivars.

The response of sweet white lupin to several herbicides was evaluated over five years at Charlottetown, Prince Edward Island (PEI) and two years at Cornhill, New Brunswick (NB). Excellent crop tolerance was found to the herbicides: chloramben, ethalfluralin, fluazifop-P, linuron, metobromuron, metolachlor, and trifluralin. None of the above herbicides affected crop grain yield or 1000 seed weight. Sweet white lupin was slightly injured by metribuzin at 500 g ai/ha but yields and 1000 seed weight were not affected. Higher rates of metribuzin reduced lupin yield and 1000 seed weight. Imazethapyr applied POST with 0.25% v/v Agral 90 and 1.0% v/v 28% N fertilizer caused severe crop injury and reduced lupin yields.

A field experiment was conducted comprising two varieties of mungbean, BARI Mung-5 (V1) and BARI Mung-6 (V2), and five levels of phosphorus fertilizer: triple super phosphate [Ca(H<sub>2</sub>PO<sub>4</sub>)] viz. T1 (control), T2 (42.5 kg P ha<sup>−1</sup>), T3 (85 kg P ha<sup>−1</sup>), T4 (127.5 kg P ha<sup>−1</sup>), and T5 (170 kg P ha<sup>−1</sup>). The experiment was organized in a randomized complete block design with three replications. V1 produced the highest number of pods per plant (7.65), whereas the maximum 1,000-seed weight (49 g) was produced by V2. The maximum plant height (30.89 cm), number of branches per plant (8.55), number of leaves per plant (19.05), number of pods per plant (10.25), pod length (8.95 cm), number of seeds per pod (9.11), 1,000-seed weight (48.17 g), and yield (1.05 t ha<sup>−1</sup>) were obtained from the T4 treatment. The interaction of phosphorus levels and varieties had a considerable effect on the growth, yield, and yield attributes of mungbean. The highest number of leaves (20.44) and number of pods (10.39) were obtained from V1 when 127.5 kg P ha<sup>−1</sup> (T4) was applied, whereas the maximum number of seeds per pod (9.25) and maximum pod length (9.09 cm) were obtained when  85 kg P ha<sup>−1</sup> and 42.5 kg P ha<sup>−1</sup>, respectively, were used. The highest number of branches per plant (8.87), 1,000-seed weight (52.83 g), and the maximum seed yield (1.14 t ha<sup>−1</sup>) were achieved from the treatment V2T4 owing to the interactive effect of phosphorus dose and mungbean variety.

Watermelon [Citrullus lanatus (Thunberg) Matsum & Nakai] is a plant that is widely cultivated and contains important nutritional compounds such as citrulline, arginine, and glutathione. In the last few years, the consumption of vegetables and fruits in Indonesia has tended to increase but cannot be fulfilled by domestic production. Yields are influenced by the character of yield components. This research aims to study the relationship between the character of the yield components on the yield in the watermelon. The study was arranged in augmented design and planting material are 75 watermelons genotypes and 3  checks varieties. The results showed that there are some characters of yield components that correlated with yields. The characters of yield components that have positive genetic correlation and positive phenotype correlation with fruit weight are stem length, number of branches, fruit stalk length,  fruit length, fruit diameter, thickness of pericarp, number of seeds per plant, and weight of seeds per plant. The yield components characters that have a negative genetic correlation with fruit weight are day to flowering. The characters of yield components that have positive genetic and phenotype correlation with seed weight per plant are fruit weight, stem length, fruit length, fruit diameter, number of seeds per plant, seed length, and seed width. The Characters of yield components that have a negative genetic correlation with seed weight are day to flowering and the first female flower emerges. The characters of yield components that correlate with the yield are used as selection markers for indirect selection.

Physiological Characters

To study the genetics of seven agronomic and physiological characters (total dry matter (TDM), number of pods per plant, seed weight per plant, 100-seed weight, number of seeds per pod, pod length and root length density) which were correlated with yield, eight crosses of mungbean were made, and the agronomic and physiological characters were evaluated in the six basic generations (P1, P2, F1, F2, BC1 and BC2) of each cross. It was found that most characters including TDM, number of pods per plant, seed weight per plant and root length density showed additive, dominance and epistatic gene effects, except for 100-seed weight, number of seeds per pod and pod length. One hundred-seed weight and number of seeds per pod possessed only additive gene effects, while pod length was controlled by both additive and dominance gene effects. The duplicate epistasis revealed the presence of a large number of non-additive gene actions controlling TDM, number of pods per plant, seed weight per plant and root length density that may hinder the improvement of these characters, and confirmed that selection of these characters in later generations would be more feasible.
