recurrent parent,the progeny mean and parental means in irrigated and rainfed conditions for all the characters under study was compared using T statistics between parents and 18 BC2F3 progenies. The mean, minimum, maximum, standard deviation and standard error for all morpho-physiological and agronomic traits measured in all backcross derived lines along with parents presented in table (4.3a,4.3b,4.3c). T-test reveals that mean of MABB derived improved lines were not significantly different from mean of high yielding recurrent parent GW322 and donor HI1500 under stress as well as non stress conditions . The phenotypic performance of improved lines for the traits associated with drought tolerance and other agronomic traits were similar …show more content…

Progeny mean of these lines for canopy temperature at booting was 17.74, at heading 20.78, at anthesis 26.7 and at grain filling 29.67 as compared to parent GW322 with 18.2,22.2,26.18,31.96 and 18.2,24.3,28.4,34.5 at booting, heading ,anthesis and grain filling stage under non stress and stress condition respectively which was comparatively less than recurrent parent. For chlorophyll content measured by ,SPAD was ranging from 49.34 to 44 from booting to grain filling stage in progenies and 47.6 to 44 and 43 to 36 in GW322 under non stress and stress condition respectively. Similarly, NDVI, Vegetation greenness index recorded in booting to grain filling stage in progenies was 0.67 to 0.5 when compared to parent with 0.61 to 0.51 under irrigated and 0.54 to 0.36 in rainfed condition which was not found to be affected due to water stress. SPAD values and NDVI was started declining in postanthesis to grain filling stage in all MABB derived improved lines. Staygreen scale of 2.6 obsreved in GW322 in irrigated and 2 under rainfed condition as in case of progenies it was 6. Mean yield per sq. meter was 582.48 (g) and thousand kernel weight 44.84 (g)
