'Gonji10ho', a new variety of Neolentinus lepideus, was bred by mating two monokaryotic strains isolated from 'GMNL66037' and 'GMNL66014' in Mushroom Research Institute, Gyonggi-Do ARES in 2012. The optimum temperature for the mycelial growth of 'Gonji10ho' was $29^{\circ}C$ on PDA medium and that for the primordia formation and the growth of fruiting body of 'Gonji10ho' was $20{\pm}1^{\circ}C$. In bottle cultivation of 'Gonji10ho', the period of spawn running was around 35 days at $22{\pm}1^{\circ}C$ and the period from scratching of inoculum to harvesting was 27 days. 'Gonji10ho' had thicker pileus and stipe than control variety('Solhyang'). The number of available stipe was fewer than that of control variety. During the cultivation of 'Conji10ho', the occurrence rate of Trichoderma spp. was lower than that in control variety. In bottle cultivation, the yield of fruiting bodies of 'Gonji10ho', which was 38% higher than that of control variety, was 69.6 g/900 ml bottle, and in bag cultivation, that of 'Gonji10ho', which was 10% higher than that of control variety, was 114.2 g/1 kg bag. In physical characteristics, the strongness and brittleness of the pileus of 'Gonji10ho' were higher than those of control variety. When considered in the period available for sale, the shelf life of 'Gonji10ho', which was 5 days longer than that of control variety, was 34 days.

A new flue - cured tobacco variety KF113 was developed by Nicotiana africana method from a cross of NC82 and Coker 347 at the Suwon Experiment Station. It was tested in the 0fficial Variety Test in 1991-1992 and the flue - cured Regional Farm Test in 1992. KFl13 flowers 4 days later than WC82 (standard variety in Korea) and its harvestable leaves are 2 more than those of NC82. The leaf type and shape of KFl13 resembles Coker 347. It has high resistance to bacterial wilt (Pseudomonas solanacearum) and black shank (Phytophthora parasitica var. nicotianae), and is susceptible to tobacco mosaic virus. It should adapt well to the flue - cured production area and can reduce premature flowering under unfavorable weather conditions. Yield of KFl13 is 5% higher than that of NC82, and nearly equal in value per kg compare with NC82. This variety met acceptable standards for chemical and physical characteristics of cured leaf and for smoking taste evaluated by panel members in Korea Ginseng & Tobacco Research Institute.

Purpose - Recent international studies have largely focused on measuring the welfare gains from increased trade varieties. To adequately capture the variety gains, it is of importance to estimate the elasticity of substitution between varieties of trade goods because it is one of the key parameters to determine the magnitude of the variety gains. Using the import data of South Korea, this paper shows that the elasticities vary substantially across the estimators, which affects the magnitude of the gains from trade. Design/methodology - Empirical studies working on the gains from trade variety have heavily depended on the estimation methods for the elasticity of substitution between trade varieties, developed by Feenstra (1994) and refined by Broda and Weinstein (2006). We estimate and compare the estimated elasticities for 8,945 HS 10 goods of South Korea, obtained from the three estimation methods: Feenstra's weighted least square (F-WLS), Feenstra's feasible generalized least square (F-FGLS), and Broda and Weinstein's feasible generalized least square (BW-FGLS). Findings - Using the estimated elasticities from the F-FGLS, considered as a suitable estimator, A typical Korean consumer saved 228 dollars per year by the greater access to new import varieties. This leads to gains from imported variety of 2.06% of GDP. In 2017, a typical Korean consumer would gain by 611 dollars, compared with 2000. China is the country with the largest contribution (28.4%), followed by Japan and USA. About 50% of all the welfare gains come from the imports from the three main trade partners. The Southern Asian countries are more important to the South Korean welfare gain than the Western European countries. Originality/value - Existing studies have chosen one of the methods without any criterion for the choice and then estimated the elasticities of substitution between varieties of trade goods. This paper focuses on the estimation specifications and methods as the cause of the disparity in estimated elasticities and welfare gains from trade variety. According to the Ramsey RESET and White tests, the F-FGLS estimates are relatively better compared to the F-WLS and BW-FGLS estimates. As another contribution, this paper provides the first measure of the welfare gains from trade variety for South Korea, using the estimated elasticities of substitution between trade varieties.
