A field experiment was conducted at Institute of Agriculture and Animal Science (IAAS), Bhairahawa during winter season of 2019/2020 to find out the performance of wheat genotypes under timely sown (November 29, 2019) and late sown (December 25, 2019) conditions. The research was carried out in two environments (timely sown and late sown) following alpha lattice design with two replications. Each replication consists of five blocks with four plots in each block. The results revealed that all genotypes performance was decreased in late sowing environment. In late sown condition, there was significant difference among genotypes for all the traits under study and under timely sown condition, there was significant difference among genotype for all traits under study except weight of grains per spike and grain yield. The maximum yield was recorded in NL 1179 and Bhirkuti in timely and late sown conditions respectively. It was found that the mean grain yield in timely sown condition is 90.77 % higher than in late sown condition. The maximum grain yield was recorded in NL 1179 across combine environment. Int. J.

Radicular cyst is believed to be derived from the epithelial cell rests of Malassez. The associated tooth is nonvital, usually asymptomatic, and may result in swelling, tenderness, tooth mobility, or other problems with rare possibility of neoplastic transformation of its epithelial lining. The treatment options include endodontic procedure, extraction of offending tooth, enucleation with primary closure, and marsupialization. The present report describes the case of a radicular cyst of anterior maxillary region in a 31-year-old male patient, with a detailed description of clinical, radiographic, histopathologic features, pathogenesis, and its surgical management.

Glandular odontogenic cyst is a rare developmental odontogenic cyst that bears similarity to several other odontogenic lesions. Till 2017, only 169 such cases have been reported in the literature. Herein, we describe one more case of it occurring in a 35‐year‐old female patient.

Assessment of variability and traits association in crop help to enhance selection efficiency. Therefore, the present investigation entitled “Variability, Correlation and Path Coefficient Analysis for Agro-morphological Traits in Wheat Genotypes (Triticum aestivum L.) under Normal and Heat Stress Conditions” was carried out during winterseason of 2019/2020 at Institute of Agriculture and Animal Science (IAAS), Bhairahawa, Nepal to identify traits that highly contribute to grain yield and suitable for its further improvement. The experiment was laid out following alpha lattice design with two replications. The twentygenotypes of wheat was sown in two different environments viz., irrigated and heat stress in November 29, 2019 and December 25, 2019 respectively. It was found that under normal condition, moderate GCV and PCV were recorded in SW, TGW, NGPS, and WGPS. Under heat stress condition, high GCV and PCV were observed in GY. High heritability and high GAM was observed in TGW & GY, NGPS, WGPS, TGW under normal and heat stress condition respectively. Under normal condition SW exhibited positive correlation and high positive direct effect on GY at genetic level and WGPS at phenotypic level. And under heat stress condition SW exhibited positive correlation and high positive direct effect on GY. Whereas, at phenotypic level, WGPS and PH exhibited high positive direct effect on grain yield. Hence it is clear that spike weight and weight of grains per spike are important traits for grain yield improvement. Int. J. Appl. Sci. Biotechnol. Vol 9(1): 65-74
