ROLE OF MORPHO-PHYSIOLOGICAL ATTRIBUTES ON YIELD IN LENTIL (Pages : 42 - 45)

The experiment was carried out in Rabi season (November-March) of 2008-09 at the experimental farm of Bangladesh Institute of Nuclear Agriculture, Mymensingh (240 75´ N latitude and 900 50´ E longitude) to investigate variability and correlation for morpho-physiological, yield attributes and yield in 16 lentil mutants/cultivar. Results revealed that high yielding genotypes, in general, showed taller plant, higher number branches plant -1 , greater leaf area index (LAI), total dry mass (TDM) plant -1 and absolute growth rate (AGR) than in the low yielding ones. In terms of seed yield, two mutants, LM-31 and LM-44 produced higher seed yield attributed for higher number of pods plant -1 and bolder seed sizes. In contrast, LM-135 and LM-201 produced lower seed yield due to production of fewer pods and smaller seed sizes. Seed yield and pod number had highly positive and significant correlation with branch number and TDM, and TDM depends on branch number, LAI and AGR indicating yield could be increased by increasing dry matter production through increased LAI and AGR. Hence, these traits could be used for the improvement of seed yield resulting in the evolution of high yielding varieties of lentil.Download
