Inheritance of drought tolerance in cowpea

Y. Mai-Kodomi; B. B. Singh; Tomio Terao; et al. CGSPace A Repository of Agricultural Research Outputs (Consultative Group for International Agricultural Research) 1999

Other claims from this paper (6)

Observation Type I drought tolerance was controlled by a single dominant gene designated Rds 1.
Observation Type 2 drought tolerance was controlled by a different single dominant gene designated Rds 2.
Observation Type 1 was dominant over Type 2 in the allelism test.
Observation The F2 segregated 3 Type 1 to 1 Type 2 plants.
Observation The authors inferred the two genes are allelic or tightly linked.
Recommendation The authors cautioned that both tolerance types may not be bred into the same cowpea line.

Two mechanisms of drought tolerance in cowpea

Other claims from this paper (8)

Observation Type 1 lines stopped growth under drought.
Observation Type 1 lines conserved moisture in plant tissues.
Observation Type 1 lines survived over two weeks under drought.
Observation Type 1 plants gradually dried together.
Observation Type 2 lines continued slow trifoliate growth.

Other claims from this paper (10)

Observation Heritability of drought tolerance in faba bean was 0.51 < h2 < 0.88.
Association Exotic (North African, Latin American) faba bean genotypes were more tolerant to drought than adapted material.
Observation Highly significant variance between faba bean genotypes occurred.
Observation Yw and Yd were correlated across faba bean genotypes (0.77 < r < 0.97).
Association Variance of Yd was less than one-third of the variance of Yw.
Observation Drought tolerance was negatively correlated with Yd (-0.41 < r < -0.22).
Observation Relative reduction of plant height due to drought is a promising indirect trait to improve drought tolerance in two sets.
Observation Heritability was 0.68 < h2 < 0.86 for the improvement of Yd.
Observation The prospects of improving Yd in faba bean are good.
Recommendation A specific cross is proposed to create improved faba bean material.

Comparative water relations and drought tolerance among alfalfa cultivars

D. M. Bonner Mspace (University of Manitoba) 1997

Other claims from this paper (6)

Observation Alfalfa cultivars differed in water relations, productivity and water use.
Intervention effect Pre-stress conditioning benefited alfalfa water relations.
Intervention effect Pre-stress conditioning yielded short-lived osmotic adjustment.
Intervention effect Droughted alfalfa showed osmotic adjustment over 0.4 MPa relative to well-watered plants.
Association Alfalfa turgor pressure was generally lost below 72% leaf relative water content.
Association Alfalfa turgor pressure was generally lost below stem water potential of $-$1.76 MPa.

Observation Heat injury differed significantly by growth stage and peaked at flowering.
Observation Heat injury susceptibility generally decreased toward maturity.
Observation PI 408.155, PI 423.827B, PI 423.759 and Pershing were drought and heat tolerant.
Observation Larger-seeded lines generally failed to germinate at −0.50 MPa.
Association Promptness index correlated positively and significantly with germination stress index.
Association Germination stress index was not significantly correlated with the heat tolerance test.
Observation Six listed lines had high germination stress indices.
Recommendation The high-index lines need further heat stress testing.
