The effect of morphological parameters in sweet sorghum hybrids (Sorghum bicolor (L.) Moench)

Abstract

The present investigation entitled "Studies on physiological parameter in sweet sorghum hybrids {Sorghum bicolor (L) Moench}" was undertaken to study the to study the effect of morphological parameter. The experiment was conducted at Sorghum Research Station, Vasantrao Naik Marathwada Agricultural University, Parbhani during the Kharif season of 2022-2023 under field conditions. The Randomized Block Design with three replications was used for the experiment of 32 genotypes of sweet sorghum hybrids. The results revealed that, Among the hybrid genotypes, plant height, leaf area, leaf area index, Specific leaf area and Specific leaf weight were recorded maximum in the genotype IIMR35A×ICSV17472 (339.00 cm), 3026A×RSSV466 (66.6 dm 2 ), 3026A×RSSV466 (3.66 cm 2 / cm 2 ), RMS10A×SSR7 (0.12 cm 2 /mg) and IIMR33A×ICSV17472 (9.77mg/cm 2 ) respectively as compared to all other hybrid genotypes. The various physiological parameters viz., Relative water content 296A×ICSV1502-1(86.67%) and SCMR value was higher in hybrid genotypes IIMR15A x RSSV589 (SCMR value 60) respectively as compared to all other genotypes. Among the phenological parameters viz., Days to 50% flowering of hybrid genotype PMS71A×AKSV473R (94 days) and days to physiological maturity of hybrid genotype 3060×11NRL (131.00 days) was observed late as compared to all other hybrid genotypes. The genotypes AKMS 90A×I-7 (scale 7) and PMS-71A×11NRL (scale-7.13) showed yellow green dry leaves at the harvest stage. The genotype AKMS30A×AKSV472R and AKMS90×SSV74 (scale 3.07) green leaf at harvest stage.
