“…Maximum broad sense heritability value for the mentioned traits indicates that selection gain to improve this trait would be higher. Similar results of high heritability for 50 % flowering period are in agreement with the observations of Mahendra et al, (2020) in Brassica rapa. Rout et al, (2019) also reported high heritability number of siliqua per plant, Seeds per siliquain Brassica juncea L. The results of high heritability for number of siliqua per plant are in conformity with the findings of MariaIslam et al, 2020 in B. rapa.…”

“…Moderate magnitude of phenotypic coefficient of variation (PCV) was recorded for number of Siliqua per plant (21.8%) followed by number of primary branches per plant (19.8%), siliqua length (16.66%), plant main shoot length (16.6%), number of seeds per siliqua (16.4%), plant height (15.8%), seed weight (14.9%) Similarly, Rouf et al, (2018) reported moderate PCV and GCV no. of seed per siliqua, 1000 seed weight; Mahendra et al, (2020) in Brassica rapa L. reported moderate GCV and PCV for no of seed per siliqua , plant height. High estimate of heritability broad sense (Ã60%) was recorded for 50 per cent flowering period (96.6%) then for 80 per cent maturity period (95.1%), seeds per siliqua (91.6%), siliqua no.…”

Background: Among the North-Eastern states, Assam is the highest in terms of area of cultivation of rapeseed and has the potential to increase productivity to a great extent. To fulfil the increasing demand for edible oils, appropriate interventions must be paid for introduction of new oilseed varieties.The suitable genotype for a particular region has to be identified based on physiological efficiency and yield. Methods: The field experiment was carried out at the Instructional-cum-Research (ICR) Farm, Assam Agricultural University, Jorhat-13, Assam during rabi seasons of 2021-22 and 2022-23. The experiment was laid out in randomized block design with three replications comprising of 22 different genotypes of rapeseed (Brassica rapa, var. Toria), viz., TS-38 (Check), TS-46, TS-67, TS-36, TS-29, TS-75-1, TS-75-1TL, TS-75-2ME, TS-75-2-MM, TS-76-1, TS-76-2, JT-90-1, Panchali, Bhawani, CG Toria-4, TKM-20-1, TKM-20-2, JT-14-5, PT-2018-09, CG Toria-3, Tapeshwari and PT-303. The crops were grown following the recommended package of practice. All the parameters were taken following the standard methodologies. The parameters under study were plant height, number of primary branches, number of green leaves, stem diameters, root lengths and root volumes, proline content, nitrate reductase activity, protein content, oil content, specific leave weight, leaf area index, net assimilation rate and seed yield. Result: The results of the study indicated a significant variation of all the morpho-physiological parameters among the genotypes. The genotype TS-75-2ME and TS-38 exhibited morpho-physiological superiority in terms of number of primary branches, green leaves and SLW. The same genotypes also recorded significantly higher seed yield.

Background: In the North-Eastern states, Assam has the highest area of cultivation of rapeseed and found to be potential hub for increasing productivity to a great extent. To fulfil the increasing demand for edible oils, interdisciplinary approaches including physiological parameters must be paid off. The suitable genotype for a particular region has to be identified based on physiological efficiency and yield. Methods: A field experiment was carried out at the Instructional-cum-Research (ICR) Farm, Assam Agricultural University, Jorhat-13, Assam during rabi seasons of 2021-22 and 2022-23. The experiment was laid out in randomized block design with three replications comprising of 22 different genotypes of rapeseed including TS-38 (Check), TS-46, TS-67, TS-36, TS-29, TS-75-1, TS-75-1TL, TS-75-2ME, TS-75-2-MM, TS-76-1, TS-76-2, JT-90-1, Panchali, Bhawani, CG Toria-4, TKM-20-1, TKM-20-2, JT-14-5, PT-2018-09, CG Toria-3, Tapeshwari and PT-303. The crops were grown following the recommended package of practices. All the morpho-physiological parameters, yield attributes and yield were recorded following the standard methodologies. The correlation coefficients of morpho-physiological characters and different yield components with seed yield were worked out from the pooled values of two years following the standard method. Result: The results indicated that number of green leaves per plant, stem diameter, total dry weight, total leaf chlorophyll content, AGR and CGR showed highly significant positive correlation with seed yield, clearly indicating their contribution towards higher yield in rapeseed. The number of primary branches and SLW exhibited significant positive correlation with seed yield. Among the yield attributes, number of siliqua per plant, seeds per silique, seeds per plant, sink capacity, stover yield and harvest index showed a highly significant positive correlation with the seed yield.
