Morphological Characterization ofNew Parental Lines (AxB) of Rice for their Production Potential (Oryza sativa L.)

摘要

In the present study, eight CMS lines and their isogenic maintainers in rice were evaluated for morphological characteristics to know their production potential in comparison with standard check CMS line (KCMS 62A). The results revealed that A lines took more number of days to 50 per cent flowering (95.37days) than the corresponding B lines (93.75 days). All the CMS lines were short statured (87.81 cm) than their corresponding maintainers (96.05 cm). Number of panicles per plant (14.84) was more in Blines than in A lines (13.12). Higher test weight was recorded in KCMS58A (25.97 g) and was lower in KCMS59A (16.19g). More number of spikelets per panicle was observed in KCMS53A (207). Higher seed yield per plant was recorded in KCMS57A (4.95 g) as compared to check KCMS62A (4.91 g) and higher panicle exertion was noticed in KCMS59A.
