Heterosis and heterobeltiosis in bell pepper (Capsicum annuum var. grossum) for growth and yield parameters

The magnitude of heterosis over commercial check and better parent was estimated to identify best crosses for growth and yield traits in bell pepper. Experimental material included 21 F1 hybrids developed by crossing seven diverse parents in half diallel mating design. The findings revealed that Arka Mohini X CW308 showed best heterotic cross combinations, recorded significantly higher heterosis and high per se value over commercial check with respect to number of primary branches, number of secondary branches, plant height, days to 50% flowering, days to first harvest, fruit length, fruit width, number of lobes per fruit, number of fruits per plant and average fruit weight. The cross Arka Mohini X CW308 also showed high heterobeltiosis for traits like fruit length, number of fruits per plant, average fruit weight and average yield per plant. Hence, this hybrid with high per se value and heterosis can be utilized to obtain desirable segregates for development of superior genotype for improvement of horticultural traits in bell pepper

Combining ability studies to develop superior hybrids in bell pepper (Capsicum annuum var. grossum L.)

General combining ability (GCA) among parents and specific combining ability (SCA) of crosses were studied to identify best crosses for growth and yield traits in bell pepper. Experimental material included 21 F1 hybrids developed by crossing seven parents in half di-allel mating design. Parents and crosses were planted in randomized block design during Rabi 2019 for estimating their combining ability. Among parents, Arka Mohini showed good GCA effects for most of the traits (number of secondary branches, early flowering and harvesting, fruit weight and yield). Among crosses, Arka Mohini × CW308, Arka Mohini × California Wonder and Yolo Wonder × California Wonder were identified as potential one for yield attributing traits based on SCA effects

Bone metastasis in ovarian cancer

Bone involvement in carcinoma of ovary occurs rarely. In a review of 103 patients over last 3 years we have seen 4 such patients (serous-2, mucinous-1, mixed germ cell tumour-1). Patients presented with severe localized bone pain, bony swelling and difficulty in walking. The common sites of involvement were vertebrae, pelvic bones and skull. Radiologically the osteolytic lesions were commonest. Bone lesions were associated with abdomino-pelvic disease in 3 patients. Cisplatinum based chemotherapy in addition to local radiation resulted in significant response in 2 patients; one complete and one partial response. The median survival was 7.5 months (range 6-39 months) after bone metastasis. We conclude bone involvement in cancer ovary is associated with poor prognosis
