Abstract
The present investigation entitled “Morphophysiological traits evaluation of wheat genotypes under irrigated and non-irrigated condition” was carried out in rabi season of 2018-2019 at farm of Botany section, College of agriculture, Nagpur, in split plot design with irrigated and moisture stress condition as main plot treatment with eight wheat genotypes viz., AKAW 4739, AKAW 4901, AKAW 5099, AKAW 5104, AKAW 4927, AKAW 4973-2, AKW 1071, AKW 381 as sub plot treatments. Treatment were replicated thrice.
The data was recorded on the basis of different morpho-physiological 45, 60 and 75 DAS, biochemical parameters at anthesis and seven days after anthesis, yield and yield attributing characters at harvest stage.
Data revealed that, wheat genotypes AKAW 5104 (3736 kg ha-1), AKW 1071 (3609 kg ha-1) and AKAW 4927 (3408 kg ha-1) recorded significantly higher yield and found 35.90 %, 31.28% and 23.97 % respectively, higher over AKAW 4973-2 (2749 kg ha-1) and significantly superior for all the morpho-physiological and biochemical characters viz., higher relative water content, RGR, spike length, number of spikes / m2, flag leaf length and width, leaf area, SMC, CCI (at anthesis and seven days after anthesis), CSI and lower plant height, canopy temperature as compared to wheat genotypes evaluated under moisture stress condition resulted in significantly increase in grain yield of wheat genotypes under study.
Among eight genotypes AKAW 4739 (3001 kg ha-1), AKAW 5104 (2929 kg ha-1) and AKW 1071 (2857 kg ha-1) recorded significantly higher grain yield kg ha-1 under moisture stress condition which was 22.89 %, 19.94 % and 16.99 % higher over AKAW 4973-2 (2442 kg ha-1) on the basis of morphophysiological traits viz., higher proline content, CSI, CCI, RWC and lower canopy temperature at anthesis and seven days after anthesis as compared to remaining genotypes and said to be drought tolerant genotypes.
Yield and yield attributing characters indicates that yield of wheat genotypes have shown significantly positive correlation with RWC 75 DAS (0.79), proline (0.81) and CSI (0.91) however, plant height at harvest (-0.56) found highly negative correlated with yield.
AKAW 5104 and AKW 1071 are identified for both irrigated and moisture stress conditions while AKAW 4973 is identified for only irrigated condition and AKAW 4739 only under moisture stress condition.
Description
Wheat genotypes AKAW 5104, AKW 1071 and AKAW 4739 sown under irrigated condition were significantly superior for all the morpho-physiological and biochemical characters. This experiment was carried out at experimental farm of Agriculture Botany Section, College Of Agriculture Nagpur during rabi 2018.
